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.

Hi guys
I'm trying to fix this laptop screen

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.

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...
