I am working on LG 47LH55 with Horizontal lines and white screen after a minute on top of the pictures, so I did not see bad tab (press on them made no difference) on the panel yet, clean and re-seat the T-CON cable, no luck. There is no active components on the LCD panel board either, check MLC caps for shorts, no luck. I will be ordering new T-CON, TV is only 3 years old.
I check the LDO RT9183-12 (1.2V) check OK.
Another thing is that I did not find any Source/Gate drive for the TFT on the panel itself which is why I do not believe it is bad panel to have that many X/Y drivers to go bad on the whole screen.
I need to look up the spec on that large IC on the T-CON to see how it works.
