Hi Chris,
Here is a list of screen faults that I have not been able to fix for long term reliability.
1 The thin line fault above. You can apply a bit of preasure to the IC but after a few weeks the IC will die, result is a few centimetres wide black line, screen U/S
2 The black line you get on certain 40" AU Optronics screens is poor vcc connection, ie power to the data driver. If you put too much preasure on the IC it will catch fire for a few secounds and burn the film connection to the Matrix and your (finger - ouch, a bit like catching your arm on the anode of a PL509.
Screen faults I have fixed in the last few years are...
001 Left side screen slow motion.
002 Left side screen dark.
003 All screen dark a bit like very low luminance and slow motion.
004 White screen
005 White and blue washed out screen using LG panel used in 42LG3000, right up to 2010 LH/LF range.
006 White and blue washed out screen using AUO panel used in 42LG3000, right up to 2010 LH/LF range.
007 Grey screen all LG models from 2007 to 2010. Mainly 42" AUO
008 Chi-Mei 26" panels grey for first 10 minutes to 2 hours.
009 White screen AUO 315XW02 range.
010 Chunghwa Dead on right side.
And many more.
When I get the chance I'll write down a "how to bodge these defect panels".
Regards,
UGM.
