Answer to: Vertical color lines at startup of lg 37le4500.zaHi Folks, just an update from me. I have been in the repair shop with the TV and they told me its bad and they were very willing to through the TV away for me. OFC I said no. Went home and look inside by myself. I have removed the main board and cleaned all the contacts and voala! The picture was back on! I suspect two things: 1. Overheating (when all the covers are put back on its happening again after it was working fine for couple of hours)... 2. The contacts are too damanged on the board (I have seen a couple of contacts in corners (those connected to the main body with black color on it - like from burning). I have scratched the black color off and cleaned that with Plum Brandy :D and when it was put back in place the picture was working).
