So this is what my Samsung 65” displays. From researching this type of image, I’ve seen similar issues declared as backlighting failures. Is that what is going on here? And if that’s the culprit, do I need to buy a complete backlighting set to properly repair this TV? Any guidance in getting pointed in the right direction would be greatly appreciated!

I finally had time to take a good look at my parents TV that was having issues. I have some pics to show what I've tried to troubleshoot it so far. First pics are with both ribbon cables connected to tcon. Image gets more blotchy and washed out over time. Next with left side disconnected. Last set is right disconnected. It works perfectly on half the screen with the right side disconnected. Could this be the tcon or ribbon cable? No physical damage to the unit.

it's my first time trying to dismantle a 55" tv and i want some help with useful methods to prevent the lcd to broke

its a daewoo uhd55

I have a xioami X43 43 inch 4K 2024 TV since purchase it has random reboot issues which service center denied because during their technician visits it would run great

Fast forward i was managing it all until yesterday the TV gave up:

MAIN THING

First it showed green lines all along the screen and started rebooting on the Google TV logo it showed purple lines all along the screen I shut it off

When I tried turning it on again later that day completely dead

Only the white light remains static on the power button no display no nothing

Trying to take off the screen at the moment. I got the bottom bezel to come off, but does the left, right, and top need to come off too? I can't find a guide or video of anyone doing this specific TV

The model for reference is: un82tu700dfxza

Trying to help my grandparents out. They sent me this picture of their tv. They have a static like bar in the right side of the tv. I had a call with them and Samsung support to help with troubleshooting. (Longest call of my life). They said a tech would come out and determine if it was covered as the tv is less than a year old. They said physical damage is not covered and is a $150 fee. I don’t know how they could have possibly physically damaged it and I doubt they did. But does anyone know what would cause this? The tv is mounted and the mount is super tight. The tv never leaves this position.

Thank you for any help

Samsung QLED
Model QN55Q75FM

It’s stuck on a blue screen that says no signal. I’ve tried connecting it to my Roku remote, doesn’t work. I’ve tried switching the channels, it always stays on HDMI2. I’ve tried changing the settings, nothing would really help. How the hell do I connect the remote to a tv that’s stuck on the blue ‘no signal’ screen? It is about 25 inches, zero buttons on the middle where the element label is, and the power cable is connected to the tv permanently. Do I have to buy a different remote? Make and model: element ELEFW328

This is an older model. I unplugged and moved my Samsung Smart TV & it's small gray cable/streaming box today. When I plugged everything back in, however, the TV said "No signal". I entered TV input. It said "PC", but my remote won't move to change it and keeps automatically exiting the menu. This has never happened before.

I tried unplugging the TV again for 1-2 minutes, as well as reconnecting the HDMI cables. Nothing has changed. The TV responds when I change volume, hit the power button, or press "TV input". If I press any other button, no response. It's just a red blink on the signal light at the remote's tip. Am I doing something wrong?

Can anyone help me troubleshoot? Attaching a video of what happens while it’s plugged in. Power recycles every 30 seconds or so, but the screen only flickers. Bought a new power cord and just tried that but no luck. It has been in storage for 3 years but was only a year old. I’m sure it’s not covered under warranty.. do I just need to buy a new one?

In the video, I demonstrate what happens when I remove one of the ribbon cables, how it stays connected, and what happens if I return it. What I didn't show was the boot loop cycle, but I did find several other threads where the OP experienced the same boot cycle I discussed in the video. I got this TV for free from FB Marketplace, and when I took the plastic backing off, I saw that there was some condensation buildup on the back, mainly near the power supply area, among many other areas. It wasn't anything crazy, however. It's worth noting that when the backlight stays on but with no picture (ribbon cable disconnected), the backlight is even, with no dead spots and no visual defects in the panel shown. Please give me some advice.

My Samsung Tv recently started having issues. Its just over 5 years old. I tried shining a light onto the screen and couldn't see any image.

Any idea what might cause this? Or if its worth the repair costs? The TV was $2,600 new.

Does anyone know anything about repairing the horizontal lines on my screen ?

Lg 55lb5900-uv

Every time I turn on my Samsung QE55QE1CAUXXN and adjust the volume for the first time, I get this popup (my TV language is German). It’s basically telling me how to use the volume/mute button on the remote.

I already know how to adjust the volume, so it’s just annoying. I’ve checked all Accessibility settings, everything is disabled, and my TV is running the latest software. I can’t find any option to disable this hint.

Is there any hidden setting to turn these tutorial popups off, or is this a Tizen software bug?

(The attached screenshot is in German, but it simply says to select the volume button to mute the sound.)

i just want to know if exist some solution withouy a technical.

its a Samsung UN40T5290 FHD Smart TV 2020.

This is an LG 50UK6950PLB. The display is white and faintly blue. I connected it through hdmi and red shows as blue, other colors don't really show. Which part has failed?

My Philips 65PUG7406/78 suddenly developed a washed-out, white/grey image. The menu and all inputs are affected. The vertical line on the screen is unrelated and has been there for a long time. Sometimes it gets worse, other times it gets back to normal for a few seconds.

The model: lf320em4a

As above

I have samsung ue55cu8072uxxh, my motherboard died, so I got a new one. Completely same BN94-18058P.
Tv works but picture is not ok. Colors are washed and there are some artefacts… So, I entered service mode and saw the panely type is set to some 65”. I opened tv, samsung usually have panel type written on sticker inside but this model doesnt. I know its HKC panel in it. Anyone experienced which type I need to choose in service mode?
Thanks!

So my issue is a pitch black screen. Nothing with a flashlight either. It started with LED blinking indefinitely so I was thinking about a bootloop, and now for some reason after opening the TV the bahaviour has become normal which leaves me confused.

Luckily I could connect to AndroidTV with ADB accepting blindly the trust prompt, grab screenshots from the home screen and everything looks fine so I can rule out firmware (still did a factory reset with no result). dumpsys display command gives me the correct data.

It has this power supply PCB : 08-L171W94-PW200AA

From my understanding, red connector goes to the motherboard (which works fine) while white connector goes to the screen. Bottom 2 pins on the white one give me 0.4V while all the others are at 0, both on sleep and turned on. But I am not sure if there is supply when the screen is not detected and I could not find a way to measure it while it was plugged on.

Is there any way for me to test the screen's power supply ? I could order a whole new board to test, but I don't want to waste money if it's the panel.

have no idea what happened. we dont believe anything bumped the tv but now I have this problem. any ideas? ONN roku brand.

Looking for feedback regarding my Samsung TV QN65QN85BAFXZA. The backlight sporadically doesnt work. For a few days the screen is dark and I only get audio then a one day it'll work again like there are no issues.

Is this only a baclight issue or whay else could be causing this to happen?

2 or 3 of the lights that illuminate my very old samsung tv have stoped working creating a darker part. The problem came and went but now it's permanent.

Is it the LEDs failing? Or could it be a loose connection or something that can be fixed without special tools or new parts? Is there a big risk of ruining the whole TV by trying to disassemble it?

As it is now it's kind of usable, but also very annoying and I don't want to make it worse, and I'm also skeptical about replacing anything inside it with cheap electronics bought from Ebay or Amazon.

My description is based on what I can see and what I've learned in the last 10 minutes of googling this problem and may not be correct.

Sorry no picture now.

From the menu it says it's a samsung ue40c5100

On the back it says model: UE40C5105QW I don't know whats up with the difference.

Model: Vizio W4K50M-1030

The Issue: I noticed a couple of soft, irregular dark spots on the screen.

What I've Observed: I ran a color-cycling pixel fixer video to check them. From what I can see, the pixel grid itself looks intact and sub-pixel colors seem to show around/through the shapes, making it look almost like a shadow is being cast from behind the glass.

Attempted Fixes: I tried gentle tapping with a microfiber cloth and a small suction cup to see if it was something stuck that would shift, but the spots haven't moved at all.

Based on how it looks in the video, is this a cluster of dead/stuck pixels.
Is that what it is or is it debris behind the outer panel?
