Hi i have a Lg 55uh661v with a black screen. Ive tried removing each tab which goes to the screen as it doesn't have a Tcon. Ive been told this can be fixed is that right? I know I've had a main board cause this fault but only as it was the incorrect one fitted by the factory

Re: LG Blank screen
Removing the TABs was not a good idea. To replace them you would need a Tab Bonding Machine......Maybe those who told you it was easy to fix have the skill and precision machinery to re-bond TABs to the screen. An incorrect Main Bd fitted at the factory......hardly likely yet possible......Then there would have been a recall of that Brand and Model.....I haven't heard of any..... -
Re: LG Blank screen
I meant the ribbons from the mainboard not the actual tabs on the screenComment

Re: LG Blank screen
Can we at least see the pictures of the whole back side of the TV showing all the boards so we can see what we are dealing with?Never stop learning

Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!
My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.
This time the original cable broke too close to the screen, it can't be fixed without tearing the screen... -
Hi all, I’ve got a problem I hope someone can help me fixi.
I have a Panasonic TX-48CX350B tv , it powers up ok but the screen is blank, the backlights are working, there’s nothing else though, no picture or sound. I’m not sure what the fault is called whether it’s BLANK/ BLACK/ or WHITE SCREEN I’ve actually came across this before on a similar tv but just ended up scrapping it, I will upload pictures of the boards etc , if anyone could help me I would really appreciate it...01-11-2025, 03:18 PM -
We have a Lenovo IdeaPad Slim 5 14IAH8 - Type 83BF for repair. The original issue the OLED screen is blank.
We have replaced the OLED screen with the exact model, also we replaced the LCD cable, but no luck.
I think there is something with the motherboard. I don't really have experience with OLED screens so far, so not sure how it should work. I have seen some laptop comes with a separate controller board, but this model does not.
Also, there is an error in Windows device manager - This device cannot start (Code 10) - Intel(R) Serial IO I2C Host Controller... -
Hi,
I have a iphone XS that came in for a screen replacement, the screen was badly cracked, and inside missing scues, on the back of the screen still the blue protector, the screen was a LCD. So we replaced the screen and all good, installed the screen and we noticed that pressing the screen with a bit of force but not excessive, the phone dies. After plugging the charger it turns back on, but again if you press it it dies. I open the phone again, and I can't see anything major, with the phone open, if I press on the logic board, battery, charging board, or even putting pressure on... -
Hello,
I am having a problem with a ASUS VH238T.
The monitor started by just going blank, but the integrated speakers, and the backlight worked. The OSD didn't pop up, neither did the messages of DVI No Signal, nor the Asus logo.
Turning off the monitor, and turning it back on made no difference. But leaving the monitor off for a few hours returned the monitor back to normal. The problem will eventually return after a couple of hours.
Today, it started exhibiting another symptom: the display started showing a white image, that didn't take the whole screen....
