Hey guys,
I recently purchased an LG 32 inch tv with a bad screen for 20 bucks. It had a bad lcd, but that did not bother me because I had another one in the shop that was brain-dead.
The one that I bought worked fine except for the screen which had streaks across it horizontally near the top, I assume data lines broken or something. I took the other set apart and got a real surprise. The main boards looked identical, but the power supplies were totally
different. The one I bought seems to be a combo power supply and back light inverter, where as the one I had already had a seperate power supply and back light inverter board. Also the one I had already, had a standard tcon board, but the one I bought had a strange el-cheapo tcon board attached to the lcd. There is only 3 months between the manufacturing dates on the backs of the sets, and they looked like identical sets. When I switched out the main boards, the set came on, and I thought all was ok, then the screen blinked off, then back on a couple of times, and shut down. I noticed that the screen was about half size, both horizontal and vertical.
Nothing I do can change anything about the on-off pattern.
The crazy part is that the main board worked fine in the other set, and seems to be the exact same board, with just a few differences in the model numbers.
I am attaching a set of pictures of the boards in this set. Pictures 1 thru 4 are from the old original set, and pictures 5 thru 8 are from the new set I bought.
If anyone has any idea of what to do to reset this thing, or maybe reload the software or something, please advise me. thanx...........
