Hello, I have just replaced the LED strips in my Sharp LC-50LB481U. However, the menu/picture is now completely shifted on the screen. Any suggestions?

Re: Shifted Screen
The screen shifted to the right and down and now has lines. Once I started to put it back together, is when the picture screwed up. I had a perfect picture once I switched out the lights and screened it up to see what it looked like. However, after putting it back together is when I turned it on to see the screen. The more I mess with it now, the more the picture becomes distorted.Attached FilesComment

Re: Shifted Screen
The picture is not shifted, you damaged the lcd screen, top left corner and likely elsewhereComment

Re: Shifted Screen
Yep, I agree with RJ. That does suck though, breaking it while putting it back together.Comment

Re: Shifted Screen
Really? The screen looks fine though, I see no evidence of damage.Comment

Re: Shifted Screen
Take it back down so you can see the whole screen and look it over real closely, flashlight laser light magnifying glass or glasses etc. it IS very easy to damage the screen or tabs on re-assembly, anyone who's never broke one is VERY lucky.Comment

Re: Shifted Screen
what do you mean "mess with it" ... what are you messing with? Good chance that if you put on your glasses and check the seating of the ribbon cables at the tcon and panel, you may find the problem. Also ensure no frame members are touching any of the boards in the "wrong places"... also the right length of screw was put back in the right place. Check around the left bottom corner area.Last edited by budwich; 04-19-2020, 01:11 PM.Comment

I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started ‘fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.
I ordered a supposedly ‘new' Tcon board this time, and... -
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... -
Have a Samsung UN50NU7400 which shows a boot screen and a screen saver if left on long enough but no picture ?
Would a moving screen saver confirm that the panel is ok or it could still be a panel issue ? -
Just had a customer bring in a M2 MBA A2681 that had had a screen replacement in April at another repairer. Since then, she has been getting intermittent kernel panics. It's an aftermarket screen, and of course it fails in diagnostics as the calibration hasn't been done. The error in the panic log is "No device added after powering on the rails".
It seems the original repairer has swapped the board and the screen to other MAC's, and said that it isn't a screen issue. From what I understand, by doing a quick search on Google, this is in fact a screen issue. The panic relates...07-31-2025, 08:37 PM -
Hello, I need your help for a failure on a laptop:
It's a Packard Bell Kayf0, motherboard LA-5021P, Rev 1.0 with graphic issue.
I received this pc because it was turning on but not displaying anything, the fans are running normally and all chipsets heat up on startup but no picture on screen, no backlight either. I noticed that ENAVDD and ENVDD are not present and that there is no LCDVDD on the connector. I didn't check the screen because, maybe I'm wrong, but if there aren't these signals, even if the screen is good, it can't display anything? I tried heating the...
