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

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.Leave a comment:

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.Leave a comment:

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....Leave a comment:

Re: Panasonic Oled TX-65FZ800E, no picture, red led blinking every 4 sec
OK I will remove the socket tomorrow at work, I have all the requested stuff.
Do you have a socket reference then I could by one on Farnell or RS web site and replace it by a new one.Leave a comment:

Here the pictures of PB-board. I add one picture showing the PCB wich has burned a little bit between 24V pins on PB5 connector and D7553. I check the D7553 diodes which have the same behavior than the others....Leave a comment:

Re: Panasonic Oled TX-65FZ800E, no picture, red led blinking every 4 sec
I am afraid I did not understand your remark Diah.
When you say disconnect from PCB, you mean from PB-board, the board with the burned white connector ?Leave a comment:

Re: Panasonic Oled TX-65FZ800E, no picture, red led blinking every 4 sec
I disconnected the black connector to remove the 24V and inject an audio/video source on HDMI1.
The result is no picture, no sound.
I checked the 12v (SVDD) and this one is switched off immediately.Leave a comment:

Re: Panasonic Oled TX-65FZ800E, no picture, red led blinking every 4 sec
Thanks Diah for the help.
I could disconnect the full black connector on the T-CON board, no signal will miss for the test ?Leave a comment:

Re: Panasonic Oled TX-65FZ800E, no picture, red led blinking every 4 sec
I did not repair the connector for now, I checked it and it was OK even if the plastic is in bad shape. I will do it after fixing the T-CON board.
About the overheating, I was surprised to but nothing obvious between a test with only the OSD and the full picture. However I am not very confident with thermal camera so I will do some new tests.
What about the Q6004 mosfet, is the mosfet here to switch on/off the 12V ?
I am interesting by any block diagram or schematics if that exists.Leave a comment:

Hello everyone, here is the issue I am facing with my Panasonic Oled TX-65FZ800e.
When the TV has not be used for some hours, I power up the TV with a video input and the image is displayed perfectly for 30seconds and then the TV switch off with the red light blinking every 4 seconds for ever.
The service manual explanation: EVDD_SOS (EVDD 24V error) with check point (oled panel, P board, A board, T-CON)
I opened it and found a burned connector on PB-board on the 24V pins.
The 24V wires have change a bit of color due to the overheat and the corresponding... -
