Default Panasonic TX-L32E5E doesnt turn on.

Hi all,
I'm coming to you for advice. On my desk I have this TV that does not turn on. When the TV is plugged into the network and the POWER ON button is pressed, only the red LED is lit.

I checked all the voltage on the P-BOARD:
6V - stynd by
16V
40v backlight

I found out that I can't get a voltage of 12V on the T-CON. Power supply 16V to the circuit IC4101 goes, I just do not know if this circuit controls the processor IC8000. Do you happen to know anyone ?

Thanks for help.

Is your processor chip intact?

Does your led come on in standby? Does it blink when you operate remote?

Do you have data sheet for IC4101. Looks like processor enables it. Maybe heat up processor and try and turn tv on.
