Re: Lg oled65e6p-u.buswljr
this cant be... R257 are 100, and it connect via jumper J75 to the socket 12VT
please be sure and test the R as the sett off not on and plugged out from wall socket.Last edited by Diah; 01-23-2021, 08:17 AM.Comment

Re: Lg oled65e6p-u.buswljr
R257 is measuring 1K. How about R258? it's measuring 10 ohm. and it's beside J75, but R296 is connected to the J75 jumper.Comment

Re: Lg oled65e6p-u.buswljr
R263 is connected to J75 and it measures 10.3 ohmsComment

Re: Lg oled65e6p-u.buswljr
yes you are correct R263.. then every things okay...
i am just have concern if your measurements had error... so please keep the power boards out side the set and make the 2 bridge and test again the voltage from down side on the boards reference to any GND on any sockets.Comment

Re: Lg oled65e6p-u.buswljr
Not getting any voltage on R263. Not sure where it should come from.Comment

Re: Lg oled65e6p-u.buswljr
SMPS take them out and test them. sorry i dont have schematic to this boards,, but you need to start testing from the transformer line until the sockets, users RJ and budm are better than me in this field to trace the issue with out schematic.. hope they will involve to help you with... until you have all voltage i can assistance you for further steps.Comment

Re: Lg oled65e6p-u.buswljr
hopefully they will step in... Thanks for all of your help.Comment

Re: Lg oled65e6p-u.buswljr
hold on... we have over seen some things... this boards had different function... you still have on the sockets which it goes to main boards one pin with 12VT_ON correct.... i cant see it very well... if yes then need to 3 jumper between 3.5V to this pin... please show clear photo on the pins labelComment

Re: Lg oled65e6p-u.buswljr
yes it had 12VT_ON LOL.... make bridge as i wrote to 3.5V so you will have 3 bridge so you will have the 12V on the sockets.. we are back to work...
after all voltage 24V and 12V at T-con socket OK.. keep the main boards disconnected from power boards and disconnected too from T-CON ( unplug the 2 LVDS from T-CON side )
then turn on show us what you will have on the screen.Last edited by Diah; 01-23-2021, 10:38 AM.Comment

Re: Lg oled65e6p-u.buswljr
Jumped the 12VT-ON TO 3.5V and got the voltages needed. With main board disconnected from T-Con and power supply, but with the power supply connected to the T-Con board with the 12V and 24V sockets, nothing comes on the screen.Comment

Re: Lg oled65e6p-u.buswljr
There is already a photo that I attached earlier. Checking the fuses I see they check ok.Comment

Re: Lg oled65e6p-u.buswljr
I just checked continuity across the fuses. I'm attaching another T-Con photo. Let me know the fuses I need to check.Attached FilesComment

Re: Lg oled65e6p-u.buswljr
Yes... that's the one's I checked. They checked good.Comment

Re: Lg oled65e6p-u.buswljr
nothings on screen? please make dark room or cover your self and the tv with blanket and then plug it in wall socket to see any effect on the screen...if totally no sign of any at the screen.. mean the T-CON dead.Comment

Re: Lg oled65e6p-u.buswljr
Nothing on screen at all. So, it is probably the T-Con board. Could it be the screen? Any way to check the T-Con?Comment

Hi everyone!
I have a Sony KD-65A1 TV with a fault – 4 red LED blinks. After disassembly and visual inspection, I found that the G76 power board and DKA board had been replaced. It is also possible that TCON was replaced, but I am not sure – there are a few marker marks that could be factory-made.
Based on assumptions, the previous service attempted to solve the issue by replacing potentially faulty components. I decided to investigate further, found a service manual, and figured out a way to power up the power supply unit autonomously and put the OLED panel and... -
Full model of the TV is 65UJ6300-UA.BUSYLOR. TV was given to me by a relative as non-operational so I'm trying to get it working so I have a nice cheap upgrade for my living room. This is my first TV repair so if it sounds a little like I know what I'm talking about, I don't.
TV turns on and has audio, but backlight doesn't turn on. Getting 230v from LED+ to chassis. Also can't see anything with flashlight test. Another forum suggested I replace the LED strips because that's the most common failure on LG TV's and the flashlight test doesn't always show results.

My Oled Tv is 55inch tv, 3 days ago I notice that middle of the screen is getting warmer and on picture I have ghosting, missing red color. Color red was still displaying, but it was not so strong as corners of the screen and watching some movies makes me angry.
Then I get an idea to take it apart and clean boards from dust.
In side of Tv was not so bad, I take compressed air in can, and gently blow up.
Also I was thinking to styrofoam sponge to isolate power board from screen that the middle of the screen will not worm so much. Because Led on screen when gets higher... -
I have three identical-spec 820-01700 boards (2.6/32/512), and ALL THREE boards came to us with the same fault, from different sources: The boards don't wake from hibernation with the keyboard or lid, they ONLY wake when you press the power button. I understand this is a very minor issue, but the boards must be fixed!
We will of course begin with the obvious (checking lid signals), but I couldn't help but notice these three boards were all 32GB variants. Has anyone noticed an issue relating to these 32GB boards in particular? I of course don't think it's a RAM issue, but it's bizarre...
