I have a LG 65 inch tv. When i turn it on it has a blue haze and slightly noticeable white vertical lines. I am wondering if this is the t-con or the panel tabs?

Dunno about the white lines but LGs (and others) have problems with the leds going blue instead of white. -

Ahhh I see.... the blue haze is from the bad backlights.
I am guessing that the white vertical lines is most likely the panel.Last edited by blake.s; 08-04-2021, 01:57 PM.Comment

if you have a backlight tester or power supply you could try lighting them up .Comment

Hello, I have a screen in where sometimes when I open it pop-up vertical multicolor lines (I would say the most of them are green). If I tun off and turn on the screen the lines dissapear or if I leave open the screen after approximately five minutes the lines gone. I measured the below voltages on the main PCB and on the T-CON board and the voltages are the same when it doesn’t display the vertical lines and when it displays the vertical lines. Also, I cleaned all the connectors very good with IPA. I moved back and forth the connectors and the COF tabs but the vertical lines didn't displayed... -
I picked up a Vizio E70-E3 for free that shows Vizio logo and then goes to a black screen. Original owner said he started having wifi issues and then he tried to reset the TV and that's when it wouldn't boot up any longer after his reset attempt. I picked up a replacement main board from eBay that matches the same model # board as the original from the TV.
Original main board - Shows Vizio logo when TV powers on, then goes to black screen. Doesn't boot up. No screen issues with any lines on start up Vizio logo.
Replacement main board - Boots up fine, but starting... -
Hello there, ive recently found an older 55inch Samsung SmartTV.
Sadly it has vertical lines at the left and one line in the middle-right.
I have already tested out the connections and have looked at the soldered ribbons of the LCD panel to see if some contacts got loose by pushing them a bit but with no success.
I have factory resetted the TV as well but also with no luck.
I am afraid that it is indeed a LCD Panel issue but there are NO scratches or any impact-marks..
A similar issue has been posted as well but also with no actual response ...Today, 04:19 AM -
This "free from a friend who was going to recycle it" SONY BRAVIA XBR-55A8H arrived with the bottom center RED LED repeating a four flash pattern. It was treated with kid gloves and was reported to have "just gone dead" and the OLED panel has no dents in the metal frame or cracks.
Thread https://www.badcaps.net/forum/showthread.php?p=1091829 helped in proceeding as follows:
1) Unplugged, then plugged set in while holding the remote VOL- and Power to factory reset.
2) Waited 30 seconds, then pressed remote Power button and "Select language"...01-30-2023, 05:01 PM -
