| PANASONIC | TC-20A12 | The device turned on with audio and a flash appeared on the screen, then turned off immediately. I replaced the vertical IC, flay-back and some electrolytic capacitors on these two circuits and nothing. | The defect was in the 140v protection circuit, because when opening the q520 collector track, the TV started working normally again (it is SMD and is located below the board). | This email address is being protected from spambots.

| PANASONIC | SA-AK250 | Crazy display and won't turn on | This sound had a crazy display and it wouldn't turn on. After doing a visual check on the volume board, I saw that tsound were some latches on the board, so I soldered these latches, the display stopped giving those crazy blinks, but now it has the keys. all functions changed, e.g. when pressing the tap key it is the FM that is activated and so on, I went back to the volume plate and realized that it was all dirty with a crust looking like dried paste, so I gave it a good cleaning on the board removing all this crust and then the sound started working properly again. | This email address is being protected from spambots.
