Hi

Thanks for using FixYa. The issue you are facing occurs due to Power supply board failure. You'll need to check the power supply board for swollen capacitors. Also check that the fans are working and there are no loose connections inside the TV. Also make sure the connector cables to and from the power board are firmly connected.

Please remember that the TV contains very high voltages even when it is in OFF condition. So, please make sure that you don't touch any unknown component/ component connections on the board.

Please do accept the solution if the issue is resolved or else revert for further assistance.

Thanks
Rylee

I think TV has weak electrolytic capacitors in power supply board that need to replaced with same value. Please check swollen top or leaky electrolytic capacitors in power supply board and replace them all but make sure replacement must be same value (that is capacitance in MF and its working volts) and put them with correct polarity pins (capacitor has plus and minus marks on it)
Thanks.

    Alright, It is weak or leaky capacitors problem in power supply board and it is not user level repairing.
    I could not understand why you rejected my assistance.
    Any way, good luck.

Why won't it cut anymore?


Not a lot of information here so I'll take a guess. If the chain isn't turning it can be frozen in the bar. The chain can also be too tight that keeps it from turning or your oiler may be plugged and not working and without lubrication it will slow the chain down.

hold down tv button and power button together until the lcd light turns on. then press the play button every 5 seconds until your tv turns off. press reverse every 2 seconds until it turns back on. press stop to save the programming code.

Everything slowly went wrong


Most likely you have a locked up micro on the main board. You would need to have the main board replaced. If the set is not under warranty your cost to repair would exceed your cost to replace.

PANASONIC CT-36SX12 IT FLASHED ON, TURNED OFF, AND NOW DOESN'T WORK AT ALL


If you're lucky, the main fuse just opened up. It takes a 6.3 Amp slow blow type. Otherwise, it could be a defective voltage regulator and related parts in the power supply I would guess.
