    Hello.

    I have a problem with LCD TV Technika 32c-914 it won't turn on when it is hot (several minutes after switch off, blinking led and won't turn on). But when I turn on energy save mode in picture menu TV starts without any problem also when it is hot.

    In power supply board was changed every capacitor for new and TV software was upgraded.

    Can you help me what else can I try?

    Thank you.

    Hi, I think you need the service manual so that you can see what Energy Save does on the power supply.

    Hello. The inverter may be damaged, disconnect it from the power supply and see if you get the same effect, if not, the power supply itself may have a fault. Check if you have PFC voltage, if any, it's best to give the model of the power supply.

    Sorry for late reply but I disassembled TV today, power supply board is 17pw25-4 and main board is 17mb62-2.5.

    I added photos of boards.
