So are improved sockets available. The bypass in post #42 looks interesting, can someone explain the procedure.

he took thick wire and connect the +24V from boards to boards to reduce the load on the socket

Exact same problem here, and same solution

cheap socket material... good job

The connector becomes very hot, more than 60 celcius, I had to pass a wire to remove the heat stress on the connector

SOLVED: Panasonic Oled TX-65FZ800E

So you were right to start by make me change all that burned stuff and now I wonder:
1- the failure is over and due to too small wires so it will happen again in 3 years.
2- there is still a component which want to die but slowly.

What do you think ?

thank you for yours nice PM.. and thanks for following up..
the common failure even professional repair persons fail with... when they ignore any socket warm up or cable too or at least color change. any of those material if there shape / color change mean the Resistances has being changed or leak accuse. and this was yours case.

human Temp 37.6° more or less for good health comparing to ... cable drives OLED cells after 10 minuets you recorded just 37° degree. this is a record better than Chinese design 1000000%

I would like to add SOLVE a the tread title but do not find how to do it.
Some help welcome.

I made a new test today, let the tv on few hours and the temperature stay stable.
So I consider the issue solve and want to thanks the strong support of Diah and lotas on this very helpfull and fruitfull forum.

I solder a new connector on the inverter board, the new one is a bit too big but after removing some pins to let only the 15 required, it fit well.
I remove the connector on the T-CON board.
I get a 24 wires cable from an old LG TV I had, exactly the same wires 24AWG, 105C, 300V.
I solder the wires on the T-CON board.
When checking the old cable wires, I discover that three 24V wires where cut. That means, 5 wires over 8 left for the global 24V power.
I made a test with a video on HDMI1 and all is working well. I checked the temperature of wires and after 10 minutes, they are warm (about 30 degres) and the main T-CON component about 50degre without the metalic plate.

So you were right to start by make me change all that burned stuff and now I wonder:
1- the failure is over and due to too small wires so it will happen again in 3 years.
2- there is still a component which want to die but slowly.

Re: Panasonic Oled TX-65FZ800E, no picture, red led blinking every 4 sec

just write the link where you find it. other wise we need the chart lable of the powerboards socket which it go to MB

[Tof]

Re: Panasonic Oled TX-65FZ800E, no picture, red led blinking every 4 sec

The service manual is a 26MB pdf file and 19MB is the maximum allowed.
Is there another way to upload it otherwise I split it in 2.

Re: Panasonic Oled TX-65FZ800E, no picture, red led blinking every 4 sec

OK I will solder wires directly from EVDD inverter board to T-CON board tomorrow to get good connections. I will go back to sockets later.

[Diah]

Re: Panasonic Oled TX-65FZ800E, no picture, red led blinking every 4 sec

the 12V are VIN. so next time please called it so. the t_CON had EVSS to montore EVDD 24.V and VIN 12V via VIN - & EVDD - so now you need to jumper direct from EVDD inverter boards EVDD + and EVDD - to the T-CON EVDD socket. notice use neu cable strong enough.. dont use any of the burned socket before.

Re: Panasonic Oled TX-65FZ800E, no picture, red led blinking every 4 sec

I removed the burned connector and plug the board again.
I plug video and audio on HDMI1, switch on the TV but no sound.
The 12V(SVDD) is switch off after 1 sec, even if I push the standby button.

Re: Panasonic Oled TX-65FZ800E, no picture, red led blinking every 4 sec

I will come back to you tomorrow for a new test result without the socket.
Diah, lotas, thanks to support me so much.

not at all from my side ... but dont do any thinks more or less as i asked you before for test pls.
