Re: LG OLED 55EC930V Horizontal flashing lines problems
There's an adjustment that can be made from the service menu but the service menu can be tricky to access.

Re: LG OLED 55EC930V Horizontal flashing lines problems
Unfortunately, even if the flashing lines are currently part of the full image, is not possible to glimpse the menues options. But I'm almost certain I already disabled the dynamic contrast years ago. The lower part of the screen is ok for about 5cm, the rest is black with random noise lines, but them never appears in the same place.

Can you get the menu up?? If you can, turn off the Dynamic Contrast- Picture- Picture Mode Settings -Expert Control- Dynamic Contrast.Last edited by nomoresonys; 04-24-2020, 06:12 AM.Leave a comment:

LG OLED 55EC930V Horizontal flashing lines problems
Thank you for your gorgeous forum.
I have a LG OLED 55EC930V, that worked perfectly hanged on the wall for more than 5 years, now, after a initial screen dim for 30 seconds, I cycled power it, and now I have this strange problem that was filmed on this short youtube video.
https://youtu.be/vgF_kTjzEe8
Since the TV in background works, it respond to the remote normally, audio works, and after reading similar posts on this forum I understand it can be the TCON board (please help me to understand if it is a defective panel instead) I found two part numbers for this TV, one, the oldest version (6/2014) have a FPGA chip, the second one (11/2014) seems to have a custom chip instead.
Original part number: 6870C-0555A
Possible improved (?) compatible part number: 6870C-0477C
With your kind help, I just want to understand:
- If behavior in the video is a panel issue
- If the problem caused, can be addressed by replacing the TCON, and if the "improved" TCON can be a better solution if compatible. (less heat)
Thank you very much for your time and your help!
1. "improved" replacement found on ebay
2. same model replacement fount on ebay
3. original part

All left and right refers to looking from rear of TV (or looking from front with TV upside down)- TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
- Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault

I am in the jungle visiting family and I always try to fix all their electronics while I am here
A few years ago I gave a family a TCL LED55P65US tv, and now i am back and it is having some issues.
There are constant, shifting horrizontal lines across the screen and the screen flashes every 1.5 seconds or so, as seen in the attached gif.
Ive been through a few troubleshooting steps and no luck so far.
Does this seem like a possible T-Con board issue or does this seem unrepairable? The tv has been in a high heat and high humidity area, and the...04-02-2024, 01:36 AM -
Hi guys
I just started fixing 4k TV few months ago. so I am still learning a lot
I got this tv from friend complaint is ghosting or horizontal lines on image.
never saw the original symptom but I took the tv back home. the funny part is that after bringing to home, the tv worked fine no issue for 3 weeks.
then it started to show the ghosting white image.
I started using the tape method, but this tv does not have a T con board and it has only 1 ribbon cable from main board to the tv panel.
it has 3 thin small boards at the bottom of the... -
Hi, I have a Sony XBR-65X750D that has horizontal lines at the bottom 6 inches of the screen. These lines appear to be every other line because the picture is still quite visible behind those lines. The lines appear all the time with a few other lines above and below the 6 inch level blinking on and off at about 2 second intervals. I'm not sure if this is a panel issue or power supply/main board problem. I did replace the T-Con board without any change in the problem. Any suggestions you might have would be greatly appreciated. Thanks, -
5.5 year old 85 inch Sony Bravia X950G started showing gray horizontal lines across the bottom of the screen and the picture shifts slightly vertically when it happens. The lines sometimes get bigger/smaller vertically and bounce back. See the video for the problem. It seems to be happening after it warms up after an hour or so. Happens regardless of source. Right now there's nothing but power cable connected and it's happening. We did hook up a new Nintendo Switch to our HDMI switching receiver today, and played for a while with no issues, but this problem didn't occur til a few hours later while...
