Re: LG 60PB6650 plasma**PINK DOTS ON SCREEN
Take a look at the back side of the board and see if you can find cracked solder joints on the Y-sustain. Take a look at the inductors. They look like coils. -

Oh those pictures are great!
Ok so you actually also seem to have a washed out picture. What that means is you fixed one problem but not all of them. You probably still have a shorted or low ohm transistor on your Y-sustain that is not allowing the board to work 100%.
Do some more checks on the board to check for shorts on the Y. If you don't find any, you may have to take them out of circuit and check them individually to see if some are really low in ohms.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 -

This laptop has dots that show up once on the windows login screen. The bios menu and windows loading phase doesn't have them.
What I have tried:
change screens but it's not a screen issue as they show on internal and external display.
Changed SSD and Windows
Wrote a new bios
Inspected if there is anything unusual on the board, none
Has someone seen this before, what could be the issue...03-21-2025, 11:32 AM -
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...
