Lg oled burn in repair11/5/2023 How long does it take to start producing that line? (Main board disconnected, Just 24V connected)Ģ.Reviewed by Adam Graham remodeling expert. Using your method to manually force the TCON do the scan&refresh cycle. (One minute because my tv goes into protection)ġ. At least the line isn't visible after 1 minute when I disconnect that 12V connector. Your method to do the scan refresh cycle with disconnecting the 12V doesn't work here. Like the scanning does work, but the compensation doesn't.īut for now I'm not completely on with the next step. I repeated this 3 times and there's totally no difference. Not easy to see he adresses the whole WRGB, or only the white ones. It's a very thin line, but in my opinion it seems like it's just white coloured. The colour on the upper half of the screen is the same. This mean you take out MB (main boards) totally as i described it at my post 15 yours got it direct from PWB as well the 24 volts. as the set mentioned before it got the 12v feed via LVDS from MB. !!!īack to yours mention on my post yes the idea are the same. so i don't know how its look like at top half.!! ( one color as it show or it was with some red color points ) remember the effect (burn you think ) you have it at this top half screen. its look to me it look one color however you recorded it after it was at the half of the screen. I filmed the last part of iĬould that be the bar, I had to see after disconnecting the 12V plug? After a while I got a small moving bar from top till bottom. So if nescessary I'll do it later.įor now, I forced a JB-compensation in the service menu of that tv. I understand this is the way to check the status of my pixels, right?įor trying that I have to move the tv to my cellar, because all the tools to do that are located in that part of my house. I read your suggestions like you described here: How long after providing the 24V does it take the bar becomes visible? If the software in that T-CON does that procedure without the influence of the tv, it could be solved like that. When I completely disconnect the tv’s Power Supply and the signal board, but I let the 4 ribbon cables connected and I provide 24V on the black connector (but no 12V on the other), does it also do the procedure you told me? A critical error means Standby and that’s it.īut maybe another solution: I understand from your instructions, every LG OLED T-CON board has to do the measuring/calibration procedure with the horizontal bar, when there’s JUST 24V provided and no 12V. They don’t know blinking red lights etc, to display an error. I don’t know why they choose that name, but if you select it ‘ON’, no matter what the previous condition was, he boots and stays on after plugged in into the wall socket.Ī disadvantage of Loewe is the lack of error codes. In every Loewe service menu, you have an option “Warm Up Mode”. That’s the way for example Philips works. leave it discharge and plug in back the white socket and test your picture. and please don't use the remote control at all. ![]() leave it 5 minute out from wall socket ( discharging ) and repeat to plug it in wall socket with out feed 12 volts to t-con.ĭo it for 3 time are enough. ( scan and refresh pixel ) if you do it just keep the set on for 5 minute. the set will remain working and at every start there will be horizontal line show on screen moving from top to down. If you disconnected the white socket ( 12 volts feed ) from T-CON driver and power boards. and please compare one end of ribbon cable if they have 2 wide pins from left and right. Look at my post over here ( ribbon cable photo ). ![]() So the module and the t-con driver from LG If zoomed, the part numbers are also visible. It should be possible to see what kind of T-Con is used. I had do made several photos of the T-Con, because Loewe decided to add a lift mechanism on the screen.
