Thanks for the feedback. I'll attempt to cut the frame and look for bad caps. I'm a little worried I'll damage the ribbon cable in the process.... -
I assume the panel buffer boards are between the panel and the metal backplate. In which case, it's not easily accessible. I would be ok to use the tv with the white lines, if I could reverse the discoloration caused by pixel cleaning.
If I got a used C1 TCON board, how can I prevent the pixel cleaning feature from running on it....Leave a comment:

The tv is a 55C1. The pictures from post #18 are with the C1 main board and TCON. The pictures from post #19 are with the A1 main board and TCON. Hope that clarifies things....Leave a comment:

For comparison, here is the same menus with the A1 main board and Tcon. Notice that the vertical white bars are much less viewable. I didn't run the pixel cleaning on the A1 board.Leave a comment:

I didn't see a E-Z adjust option, but I saw a Service menu. Here are the photos from the service menu and In Start menu requested....Leave a comment:

I didn't know if the A1 TCON would work with the C1 panel, just had one lying around so I tried it.
Do you recommend leaving the tv on with the original C1 TCON and main board for a few hours with changing bright images? I can try that if it will bring the picture quality back. Is there a way to disable the pixel cleaning feature?...Leave a comment:

Do you think the white bands are areas of short that need to be blocked or repaired? Are those areas with high current?...Leave a comment:

Yes, the A1 board and TCON was from a cracked screen tv.
The vertical lines were there with the C1 and A1 board and TCONs. The change in picture quality (decreased brightness, crushing black, and blotchy picture) was after pixel cleaning was performed. That's why I'm hesitant to run it again with the A1 board and TCON....Leave a comment:

So if I keep running the tv with the panel defects, it will kill the TCON?
Attached is the picture of the cable with SOS signal blocked....Leave a comment:

I tried disconnecting the TV from power overnight and that didn't bring the picture quality back.
I tried disconnecting the EVDD and kept the 12v VCC connected then powered on the tv to refresh the cells. This also didn't work.
I tried swapping out the TCON with one from an A1. This didn't power on the tv. It tried to turn on, but all I saw was a faint light all across the screen.
I then swapped out the Main board with the A1 board. Then the tv turned on and the picture was much better. However, this meant that I was downgrading the tv. This combination of...Leave a comment:

I have a Main board and TCON from an A1 that I will try....Leave a comment:

Thank you for the quick response. I'll try to disconnect the EVDD cable and leave the tv on to try to trigger the cell refresh without VCC.
Did the other member post any pictures of the process of cutting out the frame and performing the repair?...Leave a comment:

LG OLED C1 Pixel Cleaning Made Picture Worse
Hi,
I'm trying to resurrect a LG OLED C1 TV that has some panel banding. I used the TCON error bypass to get a picture. I was able to update the firmware as well. But when I performed a pixel cleaning to try to get the banding out, it made the image significantly worse. I tried to undo the effects of the pixel cleaning by performing a factory reset and IN_Stop, but that didn't work. Any way to reset pixel cleaning data? -
