My panasonic viera Plasma tv just went dead?


in no stand by power indicator, the first place to be checked will be the power supply board . check for blown fuse but before you replace new fuse you must need to check first bad component like shorted diode, transistor and transformer. then if the power supply board now working good then still the tv won't open check bad component at the SU or SD BOARD.

The power went out tonight and now the TV wont turn on. When the power went out the TV was off. I have tried reseting the TV several time to no avail. The green timer light just keeps flashing. Any ideas...


Either the capacitors are shot or the high-voltage transformer aka power supply is shot. You can test power from transformer to main board with a voltmeter. you can test the resistance/continuity of any capacitor with a mulit-meter in the ohm position.

Sony KT-T25SF8 Dead, no video or audio, low level clicking noise


Most likly the Horizontal output transistor has shorted out because of cold solder connections on the flyback transformer, and or a bad capacitor in the sweep power supply and or, a bad flyback transformer. If the set Did not blow the fuse, then mopst likly you will have a problem in the main power supply where several parts in a kit form has and should be replaced all together.

Totally dead. Vizio GV42L


If the circuit breaker was tripped, more likely the fuse inside the TV power supply might also be blown. If that is the case there might be a short circuit in the power supply components, more likely on a diode or transistor/mosfet.
Contact these website to see if they have the parts for your plasma.
Good Luck.

Tv went dead while viewing, will not power back up


You have a short somewhere in the load for the power supply. Probably the horizontal output transistor and the flyback transformer. You need to have it checked out by a tech. You may want to get an estimate. Stargazer

Sanyo DS31520 went dead


If still under warranty or if you have no electronic repair experience you should take the set back to the shop or to a repair person. Some of the solutions described below can be dangerous, TV's are very hazardous to service. Even when plugged out, TV's can store very high voltages. Squealing noise is from the power supply teling you that there is an overload condiction. The overload is shifting the operational frequency of the power supply into upper audio hearing range. Check the diodes and caps in the supply circuit and the active components in the deflection circuit. also resolder the LOPT, h-output, h-driver, and h-driver transformer. Good luck
