So I pick up this TV the screen the image flickers. After playing it I noticed that the 12v drops the same time the image flicker. I'm wondering would a bad filter cap sent dirt power causing the issue with the panel?

Re: lg 47LM4600 screen problems
Common problem with tab bonding board on the bottom side of the screen, when people clean the screen or spill something on the screen it will corrode the boards and connection.Never stop learning

Re: lg 47LM4600 screen problems
Yeah it sucks now the panel is junk just part it out since the picture did work just flicker every time it would spark at the hole in the ribbon and recycle the screen plastics of it.
But I did get 3d glass in the box and remote etc with it.

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 -
