What can I do to fix this ?

My tv keeps flashing on and off with the Hisense Roku logo, I done hit the reset and unplugged it ? Any suggestions

Tv is Hisense Roku
Model: 70A51HUR

It's an intermittent issue that seems to happen pretty randomly but usually after being on for at least an hour.

Is this possibly a loose cable or fixable with a main board replacement? Or am I looking at the main panel being the problem?

Thanks for any help.

I decided to replace the backlight on this TV today because the picture had started looking blue. I’ve never worked on electronics before. The YouTube videos are relatively easy to follow, but there’s one thing I don’t understand: how do I remove the panel? I’ve already removed everything that’s required, including the frame, but the panel still won’t come off.

Hi, I got a Samsung UE70RU7025KXXC 70" TV with this screen problem.

The picture keeps jumping and looks distorted, with lines appearing on the screen. There is also a darker area on one side.

I saw someone mention that putting a small piece of tape on the ribbon cable fixed the same problem.

Has anyone had this issue with this TV? Do you know which ribbon cable I should check?

Thanks!

So I had some white spots developing and went in to the led bulbs and tried DIY to fix it. Sadly some white spots where fix and i ended up with this screen now. Is it fixable and what did i do wrong. I took the screen off on my bed and just flipped it over ... so im curious what I did wrong to get this discoloration

These streaks just recently appeared along the bottom edge of my 10 year old tv. I know it's probably not worth fixing but just in case I thought I'd check to see if there's an easy remedy. From what I've read here, I suspect something has come unglued along the bottom edge as it appears lighter all the way across.

I just bought this 65inch Lg Tv and it has these 3 red dots it’s most noticeable when a darker screen is on and it’s fresh out the box.

Need some quick help/advice. I'm trying to replace my power supply board on my Sony KD-75X85K. I was in a hurry when I ordered the replacement part and didn't realize there were various models. The new board seems to be identical to the older one except for the 4 pronged connector that the board slides into. The solder points seem to be the same, so my question is can I just swap those connectors and the TV will work properly? The new one has pins, while the original has slots.

I’m replacing the backlights on a Samsung **QN75Q70TAFXZA (FB03)**. I have the bezel and side/top retainers released, but the LCD is still attached along the bottom.
The **white bottom frame (BN96-50342A / BN61-16766A)** is still clipped to the **black lower LCD/source-board carrier**.

I’ve already released the white frame from the metal chassis. Does anyone know **exactly how the white-to-black clips release** without damaging the LCD or COF ribbons? Photos/video of the clip mechanism would be greatly appreciated.

I replaced the Tcon board (replacement board from aliexpress) but the issue is the same

Samsung un65f7100af - I started to get weird display issues on my old faithful TV. I took it down and did some troubleshooting with the Tcon, removing one ribbon at a time. One side is fine but the other side is blurry and distorted which matches what I was seeing. Would a new tcon fix this or is my panel toast? This was hella expensive when I bought it so I hate to see it go and I still get compliments on how well it looks, most people think it’s 4k. Maybe it’s time, sigh….

Our TV has these horizontal black lines, and they’re getting worse. Picture 1 is from yesterday, Picture 2 & 3 are today.

If anyone has knows what might be wrong, I just want an idea on whether this’ll be cheap to repair, or it’s less hassle to just buy a new TV.

Model # OLED55C9AUA
55” 7 years old.

I recently purchased this S90FD 65in from Costco and right out of the box it has these uniform vertical lines whenever the screen is gray. It’s even more visible on dark gray screens. Should I return immediately or will does the screen need some time to calibrate itself?

Thanks in advance for any advice.

Model number in second pic, 80” LG.

Was working just fine and out of nowhere the display became distorted. When turning off and back on there’s a brief moment of normalcy and the screen slowly freezes and bleeds (see photo). Sound works fine.

There was no storm at the time of the issue and no physical damage incurred.

Any idea what this could be caused by before we pay a tech to service? Is it just going to be cheaper to buy a new one? Super bummed

hi ive got a TV LG49UG6560, that doesnt play image, when plugged in just turn on the leds and the displays shows "ilumination", my first suspect is the PCB from the panel and my question is if anyone had a similar problem with this kind of TV, thank you

We’ve had this Samsung curved TV (model UN65NU7300FXZA) for 8 years, so it’s served it’s duty like a fine soldier. Especially through two toddlers. However, after turning it on last night this swath of dim light showed up. Not dead pixels or completely black, just dimmed. We turned it on and off but it stayed. This morning, when I first turned it on it wasn’t there for probably 30 seconds, then appeared and has been there ever since. I have zero tv experience so didn’t know If this was a telltale sign to move on or if it’s a common issue with a fix.

Hi My sony bravia x8000e started showing this line at the bottom it comes on and off repeatedly. Can anybody help with the diagnosis so I won't be ripped off by 3rd party repairs .? Thank you.

does anyone have the firmware for this TV to force an update? its stuck on the “Android” boot screen when starting up. In fact, its stuck during the animation, it never even finishes forming the word “Android.”

i cant get into android recovery mode either, holding down the power button only makes the LED blink

any help or tips would be appreciated

My TCL 55C631 recently started showing horizontal bands/lines moving upwards across the screen.

Happens on all sources, including the TV itself and menus.

Much more visible on gre tones

Not really visible on pure black or white

Happens around once every 3 seconds.

Changing picture mode changes how visible it is

Video attached. Any idea what could be causing this?

I have a Samsung LED TV (UN58TU700DF) from 2022. Recently, the TV stared getting stuck in boot loop. Following all the advice on internet, I found out

• Power board is okay because backlights work
• When I tape off pins on right panel connector one by one, I found 2 pins that were apparently causing issues. After taping those off, TV powers up and does not constantly reboot
• I hear the powerup sound, backlights are ON, but there is no picture
• I ordered a new main board from eBay and replaced it, still no picture
• The TV is newer style and does not have a separate T-con board. 1 ribbon cable goes from main board to panel
• There is a bridge cable to connect left and right panels

Any hope of salvaging this? Are there any checks or repairs I can do on those strip PCBs under the panel?

Notice this bluish green line on the far left. Buddy of mine said one of the boards is dying. Bought it in 2023 at Best Buy. Never got any warranty since i usually take great care of my my tech

Came about this suspicious looking fella. Is it a microphone and if so, can I rip it out?

I purchased this TV in January and it has started occasionally dropping the sound. Has anyone else experienced this or a similar issue?
