    Panasonic TX-65DX900E
    Good day
    I need help.
    When I turn on the TV, the green diode lights up; no picture. After a few minutes it turns off — turns on. Again the green diode for a few minutes. Then red 13 times.
    Thanks for the help

    I did some measurements.
    question cf7101 D4DAY470A037 is a ptc or ntc thermistor ?

    Chassis LA65 TNPH1142. Damaged motherboard (A BOARD). There are companies that repair this board. But the cost.

    Hello fellow repairman. You can start by reading the IC9600 SPI and reprogramming a new one.
    Good luck!
