LG 47LV5500 Strange Problem.

[Ambrosity]

Last night in the middle of watching a movie, my TV screen all of the sudden started showing weird colors. I tried everything I could apart from taking the dang thing apart to try and fix or diagnose the problem to no avail, so I started to analyze what was happening. The problem is mainly seen in white and black parts of the TV. Black parts are showing green and blue strips of pixels, while white areas are showing strips of pink. I broke down and finally decided to just open the back up on the TV. My first suspect after some research online was a bad T-con. After re-seating several cables I decided to turn on the TV while unplugging each cable to see what changes happen to the screen. When I unplug the left ribbon on the T-Con (in the attached picture, the one I unplugged is the left one that is missing from the picture), the colored strips of pixels go away, and are replaced with vertical black lines exactly two pixels in width and occur every two pixels as well (See attachments). Having seen this, I think I sort of narrowed it down to either being the main board, the T-Con board or the left ribbon connecting the two. I am not positive in how correct I am on this assumption though and would hate to purchase a new board only to have the same issue, so I figured I would come onto this forum for some advice if anyone else has gone through this problem

NOTE: I am having issues with uploading photos to my post, so here are links to the photos on Imgur:

Did you resolve the issue? What was it? My LG 47LV5500 appears to have the same issue.

LV series has BGA issues. Try heating with a hair dryer before plugging in. There are repair services on ebay. Ignore the repair kits since the BGA needs reballing.

as above try heating the mainboard with a hair dryer this should prove if its a bga issue no harm in cleaning and re seating the lvds lead too (lead between mainboard and tcon)
