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.

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.

its size and the shape of it and pin amounts.. on lg could be find at power borads too
take alook here

lotas provide the right schematics and that is exactly what I just test with my multi meter.

we have risk at the socket PIN 7 (-) & 8 (+), they are up and down same level
you need to plug the socket out under any cost.. its not hard work at all.

edit... we can run the tv with out socket.... when the fault clear you can diy it as you like later

24v schematic

thanks you lotas,,, if you have it why you make my eyes hurt lol

so we have only + &- but we have 2 caps 27585 27587 1000p 50V on half way of +

if one of these caps leaked then we should have F go out on seconderay and this is not the case..

we need to take the socket out.. under any cost.

I have got the service manual of this tv with all schematics except T-CON board if it can help.

okay thanks evdd on now confirmed.. still the socket down photo not clear to my poor eyes,,,LOL .. test with your DMM peep ton mode between the raw up 1 to 2 down , up3 to down 4 up 5 to down 6 until the end up 15 down 16 to see which are share same line

then the up raw 1 -15 between them which are read one line and the down raw from 2 to 16 which are read one line.

Here are the pictures with a closer focus on burned socket down side and EVDD_ON socket.

[Diah]

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

okay thanks... but can you please upload focused photo closed only on the burned socket from down side we cant see the green circuit chart layout ,,, and on the top right you have one socket with one cable ist EVDD ON ?

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.

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 ?

yes of course this boards are EVDD inverter boards.. i would suggest you better things.. first take the boards out and let look under side whats going on there before we do further things. always please yours photo let it focused with high resolution. so we can read any label or the soldering diagram chart

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

There are 16 pins plug.

later when he take the the i´´EVDD PCB inverter boards we will see each 2pin up & down are soldered together.

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.

turn on with remote maybe it went to STBY ... and we said from PCB pluf it out.... if now you have short on this damaged socket... the matter will be bigger

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 ?

friend.... need from PCB because later i will tell you how to repair this socket if our first test run successful

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

You first of all need to eliminate these contacts on the connector, when a large T-CON current is consumed with a bad contact, the T-CON power connection is lost and an error is triggered, you need to cut these burnt wires, strip and solder them on the other side of the power supply.

you right.. they are 8 wire the 4 burned i think they are all + and the other 4 chassis but still the middle one close to the chassis one.
