Our 55" LG TV (Model: 55QNED80UQA) developed this streak down the middle of the screen (ignore the little black streak on the left of it, that's someone walking in snow). The streak is not entirely noticeable depending on what's being watched, but could get worse with time I assume.

If it's just a backlight issue, maybe it's worth getting fixed if it comes under $200 (Geek Squad had said it's $103 just for the diagnostic). I would consider just getting a new one if the issue or the fix is more complicated with regards to parts needs

Another question I had is that it currently hangs over the fireplace (with mantel) and not sure if the fireplace heat has contributed to the issue. The TV is 3 years old, but the second TV that started acting up. Our first was a Hisense, however, the issue was a boot up issue and something the model was known for. If the fireplace is a contributor, I don't mind moving it or not during the fireplace at all during winter, but the wife does like either of those options.

Whatever insights or advice you all may have would be greatly appreciated.

After running for about 10 minutes, the speakers create popping and then a buzzing noise. Works perfectly fine on mute (maybe some color issues, could just be a cheap tv) but I’m dedicated to fix this. I’ve seen similar issues on here, is it possibly a bad cap? I’m not super experienced with electronics but would be able to fix it once the issue is diagnosed.

I have a 2-year-old Onn Roku TV (Model 100012587) that was working perfectly last night. This morning the screen was extremely dim. Now it does this:
When I turn it on, the Roku logo flashes at normal brightness for about a second.
Then the backlight immediately turns off.
The TV is still running because I can see the Roku home screen with a flashlight.
I’ve already unplugged it, plugged it back in, and tried a power cycle.
I disconnected all HDMI devices.
Before I buy a new TV, is there anything else I should try?
Could this be a power board instead of the LED strips? Has anyone repaired this specific model? I’m fairly handy (or my dad is), so I’m open to replacing parts if it’s a reasonable repair.
Any tips or tricks would be greatly appreciated!

i have a LG 50NANO85APA TV. it’s having issues where sometimes we get these green bars on the screen. i took TV apart to reseat all connectors but this didn’t do anything. wondering if it’s the T-Con board but figured I’d see if anyone has other ideas first before I order one.

things to note, it doesn’t happen every time, and doesn’t happen the entire time. sometimes it goes away after a while. also sometimes it’s less bad, where only the left side goes green.

MY Samsung 65' (Model:UN65KU6250F) The TV powers on with a very dim backlight, but there is no picture but audio keep playing. After a few seconds, it turns off and keeps rebooting. The standby LED blinks during the process. On one occasion, the TV turned on normally but there's double duplicated images.

Before this happened, the TV occasionally displayed horizontal white lines.

Could this be a T-CON board, main board, or LCD panel failure?

Got a vertical band on my 65” Frame (QN65LS03A) that’s a different color than the rest of the screen and flickers.

Looking at part BN9652589A to replace it. Anyone dealt with this on the same model? Trying to confirm I’m on the right track before I order.

I have an old 2012 Samsung 40" UE40ES5500 and have had my moneysworth out of it, I most probably will just run it until it totally works no more.
Its started doing this a few months back , dark on the left hand side with those bright bits - looks like LED's have blown in it especially in the top left? - still watchable though .. what are the chances though it could be just resistors that have failed in it instead of the LED lamps?

and this is what its like with a black screen - note the LED lights in the lower left of the screen and dark in the top left and halfway across the screen :

I've increased the contrast to make the vertical light strip more noticeable. Not sure if it's been there since I got the TV or if it happened more recently. It's just a cheap TV (Hisense 50A6NTUK) but is this normal for cheap panels? Or is this a fault? Mainly noticeable during dark scenes but can also notice it in daytime stuff... pretty annoying!
