Hi!
Got an 70 inch Philips tv model 70pus7855/12 from scraps and I decidet to give it a go. I'm an enthusiast but no porfessional in the electronics.
Found some advices watching youtube nad came up with this:
It came with no picture, after diagnosing it I found out that the right side of the T.con board was faulty.
I taped down the clock signals and I got a picture but the left side of the panel has less pronounced colours. Only the right 3rd side of the panel has good colors.
See attached picture.
I tried a few combinations to block individual clock signals on the ribbon but I am not getting any impovements. It wroks only if I block at least 6 out of 8 clock signals.
Is there a better solution to this. I have a spare t-con board an a spare main to t-con board cable, replaced them and stil no good colors on the left side. (is this a LCD panel issue or maybe a mainboard failure)
Thanks for suggestions
