    Hello.

    As in the subject of TV after connecting to the network and connecting with the button on the tv ... starts, shows what the AV input is and so it lights and works 26 seconds, then turns off for 5 seconds and turns on again and again. Does not respond to the pilot. The LED is blinking and the signal from the remote control is being sent.
    Any suggestions? Thank you in advance.

    Check the electrolytic capacitors in the power supply.

    Capacitors replaced in red, not listed in white due to lack in store.

    Do I have to change the rest to do anything else?

    All voltages are 3.5v 12v 24v

    After feeding 3.5v on PWR_ON the power supply does not turn off:


    ERROR - 50.8mV
    PDIM - 3.11V
    ADIM - 3.22V
    INV_ON - 3.1V
    NC - 1.7mV
