Re: Sharp LC-70LE640U weird screen issues
my guess its the "standard panel / tab" issue. The tabs on one side are causing issues. They can be removed and the set will operate normally in a "saved" fashion.Comment

That's what I thought. I'll pass. Thanks.Comment

Re: Sharp LC-70LE640U weird screen issues
I think you misunderstood. The set can be "repaired" for $0 by removing the tabs on the appropriate side. A steal for $100 imho.Comment

Re: Sharp LC-70LE640U weird screen issues
No, I understood. I've read the long thread on the 70" vizio but it seems in the past week there have been two posts now saying that that fix finally didn't last.Comment

Re: Sharp LC-70LE640U weird screen issues
I also have played with a 70" vizio a few weeks ago and performed the repair however in my panel, I think the owner had run the set for hours and hours with the panel being bad and may have affected both sides. When we first got the set we had the classic no picture. And after removing the tabs on one of the sides we had picture but very poor quality. It isin't always a slam dunk, but a fun project for sure. If you don't have a spare $100 to loose then I wouldn't do it due to risk but if you do it is worth it.Comment

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... -
Another TV topic!!
I got this sharp TV that when I first plugged it in it showed the sharp logo and then went to the input screen. This was about 30 seconds and then it showed white screen. Now I can't see anything but white screen. This has a separate TCON and Main.
The TCON is getting 12V and several parts are as well but the VGH line is only .5Volts which I thought is totally incorrect.
Am I on the correct assumption that the TCON is bad somehow if I'm only getting that voltage or is there something else I should check?... -
I have a MBP A1502 (early 2015, 820-4924) with a screen that will not turn on. I have swapped screens with a cracked test screen and the computer boots and the cracked screen works for both backlight and image. The black/blank screen appears to do nothing.
I have collected resistant data from the cracked screen connector pins and submitted to OBData server:

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 -
Hey everyone.
I have a 820-3787-06 board from a MBP A1398 which has a screen issue. The problem starts with a bit of noise just like old TVs when booting and when the OS is on, screen jumps are added to the little noise on the screen. The jumps are millisecond and go back to the original place.
Since there's a little crack in the corner of the screen, I thought it has to be the display. But to my surprise it wasn't since I tried it with a fully functioning screen.
The same issue isn't happening with an external display. I did a gpu/cpu stress test on external...02-07-2024, 05:56 AM
