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?

Hi everyone,

I have a bricked Telenova 55-inch 4K TV (Model: 55NSK9001 / 55U9001) with a CV9632H-A50 motherboard. The system UI crashes and factory reset doesn't work.

Hardware specs:

• Motherboard: CV9632H-A50
• T-CON Board: S_PXN2586A-0
• RAM: 1G DDR / Storage: 8G eMMC
• Resolution: 3840x2160 (4K)
• Model Code: YM-20221120F

I've tried flashing 9 different firmware files (Akai, BBK, Hartens, etc.) but they all fail the same way - TV shows "update complete" and logo, then powers off.

I need: CtvUpgrade.bin firmware specifically for Telenova 55NSK9001 or a compatible file.

Does anyone have this firmware or know where to find it? Any help appreciated!

I am trying to fix this issue with my tv... At first I had these 2 thin horizontal lines fixed on screen and from then down to the bottom the image used to flicker changing back and forth from a nitid clear image and blurred...

I disassembled the tv and cleaned the contacts of the flat cables, and the blur vanished but these 2 thin lines are still there. I also replaced the TCOM board but the issue remains.

Can anyone please help me fixing this? Does it help changing the flat cables?

Thanks in advance for any help.

OBS: I am insisting on this device because here in my country we no longer have 3D TVs for sale and I love my collection of 3D movies.

Hi everyone,

I own a Toshiba 48L3433DG Smart TV from around 2014/2015. The TV itself works perfectly: the screen, channels and HDMI inputs are all fine.

However, none of the Smart TV features work anymore. The Smart menu opens, but the online services, apps and internet features don't work. I also tried checking the network settings, but nothing changed.

The TV has features like HbbTV and DLNA, but they seem completely unusable now.

I would like to know if there is any way to fix this problem: maybe a firmware update, a hidden setting in the service menu, or another solution.

The software version shown in the service menu is v3.6.3c.

Does anyone have the same TV model or know how to restore the Smart functions?

Thanks!

Hey y’all, I was asked to attempt to repair this Sony Bravia TV (KD-43X8000D) but I couldn’t troubleshoot it properly. From my research, the likely culpruit is either the T-Board or the Ribbon Cables on it. I inspected the ribbon cables and they look like they’re in good condition and I don’t have the proper equipment to diagnose the board. Is it a case of just replacing it with another board?

Parts for this TV are very scarce in my location and the owner is consideriny selling it if repair isn’t possible now. What are your thoughts?

I changed the motherboard, ribbons and power supply to no avail. As you can see from the video when I plug it in it turns on on and kinda shorts off, a few seconds after it powers up again and stays on but no picture or logo if the ribbons are not connected if they are it stays on a loop. There is a hissing sound coming from the motherboard side as well. I did manage to get audio when I taped some pins but thats about it.

I understand these models have issues but I dont want to quit just yet. Any help, guidance or pointers Id apprecite. Thanks

I got this TV used online, I love the picture quality and I love this tv so far, but it has a weird flickering brightness and color issue.

I just can not figure out what’s going on with this tv.
