Cara Servis Printer HP 3535, 3420, 3920, D1360, 2466 Catridge Head Bergerak Kekanan Secara Keras

Friday, 30 April 2010 di 12:54 0 komentar

Kali ini kang Eko mencoba untuk sharing pengalaman tentang Cara Servis Printer HP 3535, 3420, 3920, D1360, 2466 Catridge Head Bergerak Kekanan Secara Keras. Mau tau caranya ....?

OK langsung saja yaa... berikut indikasi permasalahannya ....:

1. Head Catrid bergerak cepat dan keras sampai kadang terdengar seperti nabrak-nabrak casing printer. "glodak ,,, glodak ,....glodak ...."

2. Head Catrid tidak mau bergerak hanya ditengah saja atau kadang hanya dipinggir kanan saja.

3. Head catrid bolak balik ke kanan ke kiri dengan suara keras tapi nggak mau ngeprint.

Jika anda mengalami salah satu kejadian di atas, yang harus anda lakukan adalah :

1. buka printer HP anda ...

2. bersihkan bar encodernya dan encoder sebelah kiri yang berbentuk lingkaran ( kadang ada yg menyebut timing disk

3. bersihkan dengan lembut jangan sampai tulisan / baris kodenya hilang.

4. Selesai ...

Encoder adalah penerjemah program ke gerakan motor printer, jadi kalau kotor atau ketutup cipratan tinta atau kena minyak, biasanya akan menyebabkan printer seperti kondisi diatas.

OK demikian, semoga manfaat ........

Cara Service Monior LG 505G bergaris-garis horisontal

Thursday, 29 April 2010 di 16:53 0 komentar

Kang, Monior saya LG 505G kenapa ya kok begaris-garis??? permasalahanya ada dimana ya??? Tolong dibantu ato kurang jelas nanti saya upload Gambarnya....

Begitulah kira2x pertanyaan yg disampaikan ke kang Eko.

Cara Service Monior LG 505G bergaris-garis horisontal

Monitor LG memang sering banget terjadi kerusakan muncul garis-garis horisontal, kadang nggak muncul kadang nggak. Kerusakan seperti ini tidak hanya terjadi di monitor LG tapi juga terjadi di monitor GTC, Samsung, dll.

Kerusakan monitor muncul garis-garis horisontal atau bahkan kadang layar hanya menampilkan satu garis putih horisontal di tengah layar saja, penyebabnya adalah di bagian blok vertikalnya terutama IC Vertikalnya.

Biasanya terjadi keretakan solderan di IC vertikal ini karena panas. Jadi solder ulang aja biasanya sudah menyelesaikan masalah.

Tapi kalau sudah disolder ulang kok tetep sama, maka coba cek ELCO di jalur vertikal biasanya melembung / kadang nggak melembung tapi rusak.

Dan kalau semuanya sudah dilakukan kok tetep sama, berarti kerusakan ada di IC vertikalnya.

Demikian sharing pengalamannya, semoga manfaat.....

Kenapa Head Printer bisa buntu ?

Wednesday, 28 April 2010 di 11:40 0 komentar

Jika hasil cetak printer anda putus - putus, atau bahkan tidak keluar sama sekali, maka kemungkinan besar head printer anda buntu.

Kenapa Head Printer bisa buntu ? Berikut ini penyebabnya :

* Printer jarang di pakai / jarang di gunakan.
* Jarang sekali melakukan maintain ( misalnya print head cleaning ).
* Sering berganti ganti jenis dan merk tinta.
* Terlambat untuk mengisi ulang tinta, sehingga terjadi overheat / kepanasan.

Maka printer harus dirawat dengan baik. Cara untuk merawat printer anda bisa baca di sini.

Secara technical atau detailnya kita bisa ambil contoh merk epson,
Printer epson mempunyai resolusi printing yang tinggi , satuan resolusi ini di sebut DPI ( dot per inch ), artinya head printer epson di design sedemikian rupa sehingga nozzle pada head lebih kecil daripada head printer merk lain.
Ukuran lubang pada nozzle ini jauh lebih kecil dari pada diameter rambut manusia, bisa di bayangkan, berapakah diameter nozzle ini ?

Sedemikian kecilnya, maka kemungkinan head ini bisa buntu besar sekali.

OK demikian pelajaran singkat blog ini semoga bermanfaat

Cara Merawat Printer

di 11:25 0 komentar

Ada pepatah mengatakan "Lebih baik mencegah dari pada memperbaiki !!"
Pepatah ini sangat perlu di lakukan, karena apabila head printer anda rusak , maka biaya untuk memperbaiki printer, hampir sama dengan anda membeli printer baru.
Jadi untuk itu kita harus bisa merawat printer kita dengan benar, Merawat printer ternyata caranya mudah sekali, hanya di butuhkan beberapa menit tiap minggu nya, maka printer anda akan terhindar dari masalah-masalah kerusakan printer.

Untuk menghindari dari kerusakan kerusakan printer :

1. Pakai Printer secara teratur dan berkala

Permasalahan yang paling sering kita hadapi adalah kwalitas cetak yang buruk, ada garis putih yang melintang , warna yang hilang atau tinta tidak keluar sama sekali.
Dengan pemakaian Printer yang teratur, maka kita tetap menjaga agar tinta mengalir dan membasahi permukaan nozzle.
Apabila kita jarang memakai printer, usahakan minimal tiap 1 minggu sekali kita melakukan test print.
Dengan demikian dapat mencegah agar tinta tidak kering pada permukaan nozzle.
Jika anda tidak melakukan ini, maka head printer anda akan lebih cepat buntu, dan ini berlaku untuk semua merk inkjet printer.

Tips : Anda bisa letakkan catatan kecil di depan monitor anda untuk mengingatkan agar selalu melakukan pencetakan setiap minggu secara rutin, baik untuk warna hitam maupun warna yang lain.
misalnya : lakukan pencetakan halaman web yang kaya warna atau foto ukuran kecil yang kaya warna.
Cara ini lebih efisien dari pada anda melakukan head cleaning pada printer anda.

2. Mematikan (Shut Down) Printer secara benar

Jangan lupa untuk mematikan printer anda jika tidak di pakai, cara ini juga dapat menghindari ke-buntuan nozzle pada head anda.

Penting : matikan Printer dengan on/off button pada printer anda, jangan mematikan dengan cara mencabut kabel printer anda.
Karena bila anda mematikan dengan on/off button, akan mengaktifkan mekanik capping yang akan membantu untuk mencegah nozzle mengering.

3. Jangan menggunakan kertas yang kotor atau berdebu

Jika Anda mencetak dengan menggunakan kertas yang berdebu, maka mekanik penggerak kertas atau roller paper akan lebih cepat kotor.
Jika ini terjadi maka roller paper anda akan lebih cepat aus/rusak, efeknya adalah printer tidak dapat menarik kertas.
Bagaimana bila roller paper anda kotor ?
Anda dapat bersihkan dengan Dura klin, caranya : Teteskan Dura klin pada kertas HVS polos, kemudian print halaman kosong pada kertas tersebut, lakukan 4-5 kali, atau gunakan tombol tray pada printer, untuk menarik kertas keluar.

Penting : Jangan pakai Vacuum Cleaner untuk membersihkan printer, dapat mengakibatkan short/korsleting dan terbakar pada board di dalam printer.
Tips : Jika anda tinggal di tempat yang berdebu, pakailah cover printer agar printer anda lebih terhindar dari debu, cover dapat berupa plastik atau kain.

AMPLIFIER TOA problem

Monday, 26 April 2010 di 20:37 0 komentar

Hearing the words TOA, our minds will definitely fixed on a brand ampilfier who once branded the country Indonesia, in addition to local products, amps ioa is also a topnotch amps are often used for public purposes in masarakat. but since large numbers of cheap china product entry to Indonesia, it seems that manufacturers of brand ioa is trying to compensate for their price (China) by using some components cheaper .. who as a result, now is not got amps toa more. year old home in the mushola2, seminar rooms, a stage amp dll. Now toa not as tough as before, just because of one thing: the product output ioa began the 2000s using a transistor-type C5199 .. final result if the amp is getting hot / increased temperature .work this transistor .. if you have shaky voice amps ioa "new" defective / cracked and very feeble .no problem. replace just need to type the previous output of type D1047 .. (do not forget the original, not imitation), you'll be dashing back toa ..

Sharp TV Troubleshotting

This tutorial discusses how to deal with issues / problems on Sharp TV (Silver Boxes series) more quickly and save time.
Jump at the core of the discussion:
Every time you get to the reparation. First sharp tv you have to clean it first with a brush or brush mainboardnya truncated approximately 2cm, to see and ensure there is no good who soldered joints, because the point of loosened solder who will be moved and you can see it clearly. Use high gloss paint thinner liquid (good quality and quick-drying) to clean dirty or stain on the mainboard.
Once clean, check all the solder points on the parts: supply-Flyback.blok Vertikal-Regulator/power this is the most often occurs because of heat damage to the solder point that ditimbulkannya.terutama solderan check in the feet and the vertical IC resistornya. care in the process workmanship, because this part is sensitive, even if you turn off the power was still remaining voltage on the vertical suplly elco (C: 470uf/63v).
Replace the IC if you believe the vertical or also damaged in the resistors marked with the changing colors vertikal.kerjakan carefully.
Try to turn on the TV and watch, if you still do not want to start normally, follow these steps:

If the flame-red LED to the green and stop being yellow, the damage occurred in the IC memory (24c04-24c16), replace it with baru.Setting who returned parameters used in the service menu.
If the red LED continues to die, the damage occurred on the main IC (TDA 938psxxx) or loss of voltage on the regulator 3.3volt, check the power supply.
If the green or red blinking, there is an error in the memory IC (internal error), you can reset it or replace it reset IC (IC reset the memory sharp tips will be displayed in a special tutorial).
If the LED is green for 50-10 seconds and back in red, there is a failure on the horizontal section, check the flyback (remove the scale and measure with a multimeter 10k on foot toward the ground and the leg TR.output horizontal collector, if it moves even a little means have short flyback . Also check the voltage of 180V to block the RGB, is common damage to the resistors of its boundary.
If the LED is not lit at all, check that the input power supply, check 6553/6554.ganti STR if they are damaged and do not forget to check the resistor boundary (6.8/10watt).
At the turn of 6553/54 IC STR check all diodes are mainly two diodes fruit corners, replacing them with the horse's mouth, if not STR certainly be damaged again, and this often terjadi.Bila you do not get the same diode bertype who, taking two diodes IN4007 connected in series and installed to replace every single fruit such diodes.
Conclusion:

SHARP TV series that uses the main IC TDA 938PSxxx, general and frequent damage to: SOLDE THE LESS GOOD, THE VERTICAL IC, MEMORY IC, flyback and regulators.

damage to the IC memory is varied, because there are damaged and some are because error.Pada cases caused by error or corrupted, can we overcome by logging into the service menu.
In other cases, for the Sharp series of black box that use your main IC TDA 8361/8362. broken standby often occurs on the 9V regulator, replace the IC 7809 and its twin capacitors and two resistors (18 ohm). Check whether elco 100-220uF/160Volt- IC broken .Check vertical and horizontal TR and fix all the points solder.and tips for this type if there is protectionism or tv do not want to start and only on the position of the middle leg standby.Remove the solder on reset IC is IC KIA 7045 program (disconnect the ground path her). IC serves to give the voltage on pin reset 5volt in IC program (on type SHARP 51R500) NICAM / IGR this part number: IC1003 (KIA7405).

PROJECTOR TOSHIBA Problem

di 20:14 0 komentar

projector brand: Toshiba TDP-1000.in by.indikator stand-power LED (red) lights up as it should .. if the power on, this projector does not budge at all.

After I disassembled, its voltage drop condition, it's small regulator IC are still working normal soon .. I check the feedbacknya, and not one of his optocoupler .. (I forgot type) broken. so that can not regulate well soon .. I change, and it turns out, okay.
We also never found a case of this type. you can produce images through the lenses, with normal working conditions of the voice .. you simply replace its DSP IC LD type his 1000. about you must order before to toshiba, because in Indonesia, service center not provide this type of IC.
Be careful in the process of change, because this IC position on boardnya very hard pressed.

LDP SHARP XG-MB55X-L problem

di 20:02 0 komentar

projector (LDP) brand: SHARP-MB55X model xg-L with a total death complaint, neither the indicator LED lights up / standby (complaints that are generally very liked by the technician). But not all so easy any devices ..

1.Buka five bolts at the bottom, four on the corner, one in the middle
2.Buka cover / casing above, it appears the board control panel.
3.Buka four bolts on each corner of the block regulators from the top, lift a little and opened an adjoining metal casing bolts on the side.
4.Lepaskan all connections soket2 (4 to a blower, a power cord, a circuit protector, an output regulator)
5.Angkat blocks / modules are hati2 control panel, since it deals directly with DSP blocks the light.
Of course the first time I checked was the power block suplly; fuse his condition was still normal, signs that the TR / IC switching regulatornya not short.
Blocks are divided into two regulators, one for the main circuit blocks / block to supply the mainboard and lamps.
Once the regulator turns out to observe its standby system does not work, the results of these measurements turned out regulator using IC STR-W6575 to its standby system.
Although there is no component who looks short / burnt, along with the turn of this STR IC Resistors supporters and a few small elco (10/35-22/35) .. make this device can "start" again ..
But wait, after all installed neatly back, watch your power cord when the cord input voltage / PLN, how the flame condition led indicator led his Standb? ..
1.Bila still not lit, try to confirm his position circuit protector (located on the front side of a red light, when terprotek, just press the little red button again
2.Bila red LED continues to blink / flicker, make sure all the sockets are properly installed, especially leading to the lamp socket (AN-XR20LP) and blocks of DSP (Digital Signal processor)
3. When the LED is green, back to red, check the circuit block lamp, block elco regulators.
The rest you just wait for the release of this kind look on your wall.

Note, you should never unplug the power cord when you turn off / shut down the LDP before the red standby LED indicator, even though its lights were dead.
If you have problems with its components, especially IC, it is better you contact the vendor, unless the lamp can be replaced (when forced) with Ben-Q brand.

Computer Power Supply Modification

Given the current high price of travo, so to save costs, there is no harm we use this trick to fulfill our will kebutuhun power supply. In addition to the cheap trick can also produce large ampere power supply for us. This trick is very useful for colleagues who are hobby ngebrik (istilanya) both in the 2 meter or on FM. We all know that the plane was membutukan kosumsi transmitter power supply with a large current. Hopefully this trick bermaanfaat for us all.
First we butukan is Supplynya computer power that has been unused. We can buy flea ditukang (rosokan). the most cost about 10 thousand. Please note that the Power Supply current computer is a large discharge voltage of 5 Voltnya. While the 12-volt current is rather small exit. While we need is a voltage 12 Volt. For that we need to modify in the following manner:

Search rasistor on pin number 1 IC LM 494 leading to the 5 Volt output tegangang rasistor replace with the value 18 to 22 K, connect with the 12 volt output.
Replace the R pin number 4 of IC LM 494 is to ground with 47 Ohm R
Diodes with the symbol -> <- located belt replace with 12 volt output diodes associated with a 5 volt output. Since this determines the size of the ampere.
Replace the coils on the ring with wire rod Ferrite large email.
The latter, usually disposable twin transistors replaced by C 2625 D4242
For his on swit jamper green wire with black cable.

After that modification process is complete, we stayed test results. The way most young people is by shorting the poles - the poles + on 20 ampere fuse. if you can break means the modification work and ready for use. We just attach accessories that we are good at power supply so that seems cool.

Advance monitor 15 new black

di 19:37 0 komentar

Advance monitor 15 new black indeed different from the previous series. Monitor this series using the heater voltage (tube lights) is always on even if the monitor off but still connected to PLN's power cable.

So you've Although powernya and monitor key punch die, keep the flame heater. It gives the tube to work on, like a lighted lamp kept Bolam certainly will be short lived. Eventually the tube will look dark even though the brightness and contras was 100%.

If you encounter problems like this then you should do is:
off the heater voltage of 6.3 volt power supply.
replace with 2 coil clockwise on Flyback, which one can be foot Ground and the other connects to the heater directly.
With built like this then the heater will automatically turn off if you press the power button offnya although PLN power cable still connected, so the age of the tube will be longer.

Sharp TV 25 "with dark damage

di 19:35 0 komentar

The TV is a Sharp 25 "with dark damage but the picture also looks discolored. Want to know How to Service TV Sharp 25" Black Images fade?

First of all I do is to disassemble the casing TV Sharp 25 "is. And then I immediately try to turn the screen on the flyback. Screen Manage this function is to monitor light from the darkness of the flyback. But after I try to play, Sharp TV picture" of this 25-inch tetep have not changed it was still dark and discolored.

Finally, I suspected flybacknya which leads to damage in the flyback this screennya. I've lost the original cables from the flyback screen and then I try to create their own path of the pin screen Colektor Flyback (these pins connect with the Horizontal Transistor Colector. The circuit is monitored and used to plug my work properly. Fig circuit enhancements as below:

I love VR 2MOhm intentionally to get the right light. After I connect the circuit and I try turns out the picture was still dark. Finally, I try to play his VR 2MOhm to get a screen with a higher voltage, I turn slowly and turned the TV Sharp 25 "This picture was suddenly bright and there are oblique lines to suggest that setting the screen is too bright. Finally, I try return the original screen from the flyback into the jar and TV Sharp 25 "it's my turn. and it works with a normal flame.

Why is this so? It turned out that this TV has a short tube which is between the screen with the Brightness G1 G2, and when I play this 2MOhm VR, which means I give a high voltage to the G2 Screen tubes and high voltage is what to release / free up short (konslet) between G2 and G1 this.

Here's How To Monitor LG Flatron 775FT Service Screen Parts
Top Striped and Scrolling:

1. Unloading the monitor with the opening of four screws in
close the monitor casing.

2. Open Board Monitor foundation made of iron.

3. Monitor LG Flatron 775FT damage the Upper Screen
Striped and is caused by rngkain Scrolling
vertical impaired. Then I try to check
Combination vertical all turns out ok. I check
physical components, it turns out that there elco
swell (broken) at the output of 40 volts Flyback.
Apparently the voltage was 40 volts required by the
vertical series to open the screen vertically
perfectly apart from the power supply voltage 15
volts.

4. Then I replace the broken elco (this elco
as a filter voltage 40 volts). Then my monitor
switch was still the same. Then I try to sort
This 40-volt circuit there was a safety resistor
with the size of the burned 0.1 ohms. This resistor as
fuse. The breakdown was caused by elco resistor which
been damaged so that the voltage overload.

5. Then I replace the damaged resistor with
size of 0.1 ohms. And try to turn my monitor, and
Monitor returned to the normal flame
