Panasonic plasma TV (TC-P55VT50) is blinking 7 times. I’ve already replaced the SC, SU and SD boards. Info I’ve found online indicates that the P board or A board may also be the cause. Hoping someone can help me diagnose whether it is one or the other. I’ve got a basic multimeter to take measurements but I’m not very experienced in using it. Any help would be appreciated. Thanks, Jerry
@jerryyng there is really not a whole lot left for you to do. Since you already replaced all those boards that are usually repsonsible for the 7 blink error code: 7 blinks: Driver SOS2 (SU/SD Connector DET) (SU/SD Scan and Logic IC) The only thing left would be the panel. Since you already replaced most of the boards and you want to try to replace the last two as well, it is not going to hurt it any. Just purchase those boards at a place where you can return them just in case it is the panel.
