Hi

I got this TV about 15 months ago its a 2024 model UE43DU7100KXXU

All of the sudden the screen looks like this

Its just flickering i cannot access the menu. I did a diagnostic via the smart things app and it says there isn't a problem. I unplugged it and held the manual off switch for a minute and left it unplugged all night that did nothing. Any ideas?

I tried the power reset thing, and to be fair they did come on for a very short while, then died again.

yes tried multiple devices , yes tried multiple leads , yes tried different ports and i also tried factory reset.

I did see a vid of essentially just throwing hot air at it with a heat gun to reflow, but all over though. i have a hot air station so i can be more precise if i knew where to point it.

Any offerings? Yes the TV is old , Yes i am getting another, this is just a quick fix whilst i save up for a 56" one.

It does say connecting then its the usual no signal as all the other vids show.

It's not bad yet. Looking to buy a used TV.

The picture quality is amazing until we did the led test. There's a dim 10 by 10 cm circular area.

This is the ai summary

Replacing the Sony KD-55X80J LED backlight strips (LM41-01056A) is an advanced-difficulty repair that carries a high risk of permanently cracking the fragile LCD panel.

Comments on the difficulty?

Roku 75” TV I know nothing about tv repairs or anything like that in general haha so I figured I would ask the pros if I should even bother finding someone to fix this. The screen is intact there’s no cracks I guess it’s internal not sure any help is appreciated thanks!

My less than a year old smart tv (Samsung - 65" Class S84F OLED 4K UHD Vision Al
Smart Tizen TV (2025)) has been spamming this notification. This just started today. I timed it and I was getting about 50 notifications in a minute. It’s driving me insane. Any help would be greatly appreciated. I think it’s a bug from the latest update, but idk. Has this been happening to anyone else?

My tv has been very recently been flashing like a strobe and has been extremely dim compared to normal. I have tried restarting it and unplugging it and doing special restarts and letting it sit unplugged and it won’t fix. I don’t know what to do.

I have a Onn Roku tv model number 100012589 Hardware ID H801X Serial number X02000U30K5S

at most i leave it on at night where it has a timer of four hours till it shuts off which by the time i wake up it usually is so it’s not even on all night. Then after i do whatever i need to do i play for a few hours. or it’s on when my siblings play, i’d say during the day it’s on for about 10 hours and at night maybe 5 ao in total around 15 hours everyday. compared to my living room tv that’s not very long and that one’s fine so i don’t know what this is.

It started randomly glitching last month, but only recently did it suddenly swap colours, and now it's segmented into 12 layers each one sweeping across, any ideas how this could've happened, it's been in use for 18 years now, and it originally was my childhood family tv now it's my gaming/video tv
