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?

Re: LG 65UJ6300-UA has blue haze and small white vertical lines
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... -
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.

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 -
Hello,
i order a t-con because i had bad colors on my SONY KDL-40V3000 :

Is there a way to fix the vertical lines on the new t-con ?
Thank you for your help

Thanks for offering your assistance with this. I'm an electronics enthusiast with moderate level of competence (have a decent lab with two power supplies, microscope, DSO, hot air, good iron, can competently work at a component level on SMDs, design and solder own PCBs etc). I really enjoying fixing things and learning new stuff so took up a free 58" LED TV and have been googling and watching Youtube videos to see if I can fix this! I am happy to go down to individual component replacement/strip replacement etc - it's all in the name of learning.
The issues are as follows: the...
