Accidentally damaged COF Ribbon

Can this be fixed or does the whole display have to be changed? the guy from samsung said, he can get it fixed but take the whole TV with him and it's very risky. i got a 65 inch QLED tv, Samsung Q60AA 65 TV. Can this be fixed? he said samsung will charge 375$ to fix this but the COF can be fixed by a third party for about 50$, saying this type of fix is very risky. What should I do?

LG C1 55” persistent issue

Hi all, my TV has been messing about for a while, seems to be getting progressively worse though. I turned off HDR yesterday and got almost a full day out of it with no trouble.

I’ve just come back and had a mess around with the picture settings, turned to vivid and played about with the sharpness etc. and it did this.

It’s been doing whatever that is to a lesser extent for a while, but as I say; it’s getting worse.

More than likely going to take it to a repair shop soon as am at my wit’s end, unless anyone here has any ideas, whether it’s something simple enough to fix myself.

Sony KD 55x9000h TV won't start

I've had my Sony KD 55x9000h for around 4 years. I recently went away for a month, so I unplugged the TV before leaving.
When I returned, I plugged it in and used the remote to turn it on. It seemed to take longer than usual to display the home screen. I turned it off with the remote. Later when I wanted to watch it, the TV wouldn't start. So I tried the button under the Sony badge. Nothing.
I tried a different power source, unplugged the soundbar and tried all the youtube solutions. Nothing works.
Any suggestions before I get an overpriced serviceman in?

Samsung G70B repair question

So I bought this G7 (LS32BG702ENXGO) for $20 knowing it was broken but willing to gamble on a repair. Here's the issue;

Pic 1; it comes on and has a large black bar and artifacting across the bottom, resolution, refresh rate, and input method don't change it majorly, there're some differences like the speed at which the white lines flicker and where they are but nothing that comes close to fixing it

Pic 2; once the monitor warms up the bottom of the panel actually does display color but still has the vertical lines and takes about 30 seconds to 5 minutes to change color

What do you guys think, failed panel and bin it for parts or could it be a t-con/mainboard failure and fixable?

Insignia TV takes time to start

I have an old insignia tv. Takes time to start, like 5-10 power button clicks or 2-3 mins. Eventually works though. I opened up the panel to check if any capacitors are plump, but they all seem fine. Anyone see anything weird on these boards? Or maybe the buttons panel is to be changed?

Got the mainboard replaced today, then turned off after watching for a few hours, and this happened and it won’t turn on anymore

Failure or damage?

I own (and love) a Hisense 55 U8K TV. Recently a small black speck appeared on the display, that I attach pictures of.

Do you think that is a display failure of some kind or was it physically damaged? Asked differently, is it a warranty or insurance claim?

Thank you so much for any advice.

Constant pressure on LCD

First of all, I'm sorry if it's not appropriate to post this question here; it felt like the right place, but I'm not sure.

I just bought a tablet and a mounting arm/clamp to go with it. The issue is that the (padded) jaws of the grip are ever so slightly narrower than the tablet's thickness (given the specs, it's 10 mils/¼ mm, but that's counting the padding, which is a ~1 mm thick silicone-like overmold), therefore putting a tiny bit of pressure.

Once mounted you can see an ever so slightly grayer blotch when something black is being displayed (and I mean _slightly;_ in a fully dark room with maximum background broghtness it's barely noticeable).

I wanted to take photos, but the effect is so tiny it's impossible to capture.

My question is: would this damage the LCD in some way over time? I know that a hard hit or large amounts of pressure will irreversibly damage an LCD (and I obviously don't mean by cracking it), but IDK if such tiny amounts can have a similar effect.

Can this be fixed?

TV came with the house when we moved in, it has a black bar running down the middle that is permanent. I don't need the TV necessarily but if it were possible for it to be fixed I'd prefer for that to happen

Can anyone tell me, what's Technically wrong in My TV, i am including details that will surely help you, help me!

My TV was barely used and has no water or physical damage. One day it started showing vertical/horizontal lines that gradually got worse. It now sometimes shows a normal picture but intermittently glitches, blacks out (screen goes black but sound/OS continue), or shows heavy line artifacts.

What I found and did

  • Opened the TV and found dead and live cockroaches inside; there was some droppings on the PCB. I cleaned the board with PCB alcohol and brushed away the droppings.
  • Cleaned connectors and ribbon contacts, reseated ribbons.
  • After removing and reinserting the two ribbon cables, the TV boots but now glitches every 5–20 seconds (previously it glitched every second and never showed a stable image). Sometimes the screen goes black but returns automatically. Sound/OS remain running.

Would it help to know, that these were the voltage readings on the Tcon board. i am just a noob, who got a multimeter and normal stuff. The TV model is Mi 43 4A 2018 model.

  • VGL = -5v
  • HVDD - 7.9v
  • VDD - 16.2v
  • VCOM - 6.17v
  • VGH - 28V

Can anyone point me in the right direction? can anyone read these symptoms and predict where the problem could be coming from? is the panel shorted? or the Tcon or the main board, is this issue from any particular electronic component? if you want to instruct me to check exactly what with my voltmeter and where.

if you will tell me, i will follow your instructions and comeback with my findings. 🙏🙂

No Power Sony XBR-65X900H

Hey everyone,

I’m working on a Sony TV that won’t power on at all (no lights, no response).

Here’s what I’ve done so far:

  • Verified ~120V AC at the power input (CN6101)
  • Checked the fuse on the power supply board (good continuity)
  • Tested standby voltage (STBY3.3V) → reads 0V
  • Tested using chassis ground and GND pin directly
  • Confirmed multimeter is working correctly

I replaced the power supply board with a known replacement (APS-435), but I’m getting the exact same result:

  • 0V on STBY3.3V even with the board fully isolated (only AC connected)

I also checked:

  • Different grounding points
  • Multiple pins on CN6401
  • BL_ON shows only a few millivolts (~40mV)

At this point I’m trying to figure out:

  • Is it likely I received two bad PSUs?
  • Or could something else (main board, etc.) be pulling standby down even when disconnected?

Any ideas or things I should test next would be appreciated. I feel like I must be missing something. I can provide more photos if needed.

Thanks!

I ordered a replacement T-Con board for my 55-inch Philips TV, but the screw holes don’t line up with the original.

The upper one is the new one. What should I do?

OneplusTV has sound and faint image, but no backlight?

Hi everyone, I’m running into a common issue with my oneplus TV, The TV turns on and I can hear audio, but the screen appears black. I performed the flashlight test and I can clearly see the UI icons and images behind the screen, which confirms the panel is displaying content.

Does this point specifically to a failed LED strip or a faulty LED driver/power board? Any advice on a repair path would be appreciated!

Samsung S95B

Does this look like physical damage to anyone? Trying to help a friend with fixing it but he tells me he never hit it or anything. Could it be a main board issue or did something physically damage the screen?

Samsung TV

red power LED blinks red at random times and it won't power on. the LED acknowledges when I press the power button on the remote, but nothing pops up

I don't have the model or anything, I've worn myself out trying to isolate the issue. If I am told I need the information then I will look for it

Picture distortion

Have a client that her backlights were clearly out, the TV was super dark. Put in new backlights and she was floored about how vibrant it was, but then this happened (see top distortion). What I wasn’t aware of, is that apparently she’s familiar with this failure mode, just a much darker version. It starts off ghosting for a minute but then stays like this. She didn’t tell me in advance because she thought that was another symptom of the backlights that would be resolved. Is potentially this a panel problem, or a board problem..? She runs her cable through HDMI, not sure if that’s relevant or not.

I feel bad cause she was using it before, albeit dark, but fine in her world.

Any help appreciated, TIA.
