The constraints that are often experienced by sharp tv model is protected. stanby live awhile ago. such damage is caused because the voltage on one circuit there is a drop. try to pull the pin voltage solution in each circuit, eg voltage vertical IC, tuner, video, chroma IC could also be from the heater voltage. If the above steps have been done but sharp tv blm also try hanging flame ground pin on IC601, usually turn on the TV series CD90RDA1 ago. if tv sharp flame under normal circumstances can this IC should be replaced. nice sharp tv again.
