Re: LST04 LCD Screen Tester
Was going to get one but to me it is just going to tell if it is mainboard or t-con/panel problem. Wish they had a tester that could just test the panel itself. But for the price it can eliminate the mainboard as the problem.I assume no responsibility for any stupid suggestions I might post.Comment

Re: LST04 LCD Screen Tester
Small monitors but I don't think you can bypass the t-con on tv's and test just the panel.I assume no responsibility for any stupid suggestions I might post.Comment

Re: LST04 LCD Screen Tester
I believe that you are correct in that it can test laptop LCD panels but TV panels through the Tcon board.
I'll be keeping an eye on it to see how it develops.Willing to help but I'm no expert.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... -
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 -
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 everyone, I’ve just been given a Samsung UE55JU6800K smart tv as it had white spots on the screen due to the led lenses falling off. After refitting them & putting the tv back together I thought it was a nice easy fix for a free bedroom tv , then I tried it before screwing the back into place. I realised that the right side of the screen was darker than the other side, I removed the screen again as I thought the backlights had failed but they are fine.
I put the screen back in place & turned it back on . The screen seemed to be ok again but different screens on the same... -
I have the DA0ZPVMBAD0 rev d logic board and it doesn't boot up. I see all the voltages are okay. So I suspect the issue is bios.
When I power on with fn+ esc the blue light start blinking on mainboard.
I guess its a good sign. As all the voltages are okay and also charging indicates orange light when battery connected, I think it confirm that the EC bios is okay. So I ignored the ec and flashed main bios with 32mb bin file provided in the link below. But the condition is same.
