I inherited this tv, the complaint is that a horizontal line was on the screen. Upon inspection the "line" is while running at 1080i, the bottom half of the screen is squashed to be about 1 inch high, then there is a lot of noise after. The top half is perfect. Any other resolution is beautiful(coming from my laptops HDMI) the component input is perfect as well. I was wondering if this could be a cap issue? I find it odd that it only does it at that resolution, and only the bottom half of the screen. Any suggestions would be appreciated.

doesn't seem like a cap issue, not sure what it could be though.Comment

Re: Westinghouse LTV32w6hd peculiar behavior
I'd guess the problem lies somewhere on the mainboard. If it were the LVDS cable, T-Con board or panel, all resolutions and inputs would have behaved the same.A working TV? How boring!Originally posted by PeteS in CAComment

I also found out connecting it to the Roku, it says invalid format for 720p, and loops flashing snow, then the image, while at 480p.
I tried heating, nothing changed, i dont have any freeze spray at the moment.Comment

Re: Westinghouse LTV32w6hd peculiar behavior
I'm thinking that too, I was just wondering if anyone had any idea as to what specifically was causing it. I'm trying to avoid to paying for a new mainboard, hopeful it's an easy component fix.Comment

Mainboards as a whole are difficult to diagnose and repair. Check all voltage regulators for proper output first.Comment

good night! I have this screen that looks half black and half white. the tcon gives a low vgh value (5-6v). the rest seem fine. I first removed the flex from one half of the panel and then the other. Removing the left, vgh increases it to 25-26v. I think the problem is in that area, but there are not many elements on the integrated controller board. there are no shorted capacitors. could they be a cof? Some help?
By the way, now the entire screen is black. Maybe some flex was not connected correctly... I have exchanged the flex and there are no variations, I don't think they are the... -
I found another post on this site the other day which has been very helpful in troubleshooting this issue I am having with my tv. The left half of the screen is dark, and the other half is VERY slow to generate it's image - and it only generates part of its image at that.
Based on this yt video, I have narrowed it down to an issue (short?) on the left side of the display, somewhere in the system of ribbon cables.
when I remove the bezel and the rear cover, I can get the image to display correctly by manipulating the ribbon cables on the left side which connects the left lower display... -
The 55" LG has been in the basement for a few months without being used. Turned it on yesterday, set came on as it should and showed a complete screen for about 5 seconds (was on a broadcast channel but no antenna was connected), then the screen went mostly dark with about 1/3 of the screen on the right lighting up with brighter lines in that lit part (sorry, no pictures of that). Power LED was cycling too, preventing the TV from fully powering up.
Pulled the back off, all boards looked OK. Pulled the LED connector, turned the set on to see if it would power up but I don't belive it... -
Hi
I have a QN65QN90A which was purchased around launch I guess making it about 1.5-2 years old... had been working fine until a few days ago, simply went black and would no longer turn on (at all). No standby light and no typical PSU relay click etc. Absolutely dead.
Pulled it apart without doing much research first, suspecting the power supply as it had a faint buzz (I guess due to the forthcoming found short), investigated PSU for some time and concluded there was no fault that I could spot with the board removed.
Came to learn after a bit more research... -
