I have Akai 50" plasma that don't work, I was told it needs new main video board, first I was told it needs main board but when I got it didn't help so now I am looking for main video board to see if I could bring it to work.
One source for parts is Discount Merchant dot com. I bought a part from them and then canceled and got a no hassle refund. Other than that, I can't say much about them.
