I have a Sanyo 42 inch DP42D24 serial number B4460185601150 numbers

I have a 42 inch Sanyo TV DP42D24 serial number B4460185601150 numbers on TCon board 42 6871L 3398EDKARVW13062 that suddenly the left side of the screen went black. I cleaned the cables and it worked perfect for about 3 days and it did the same thing. Tried cleaning the cables again and the wires started to crumble on one of the cables. Sanyo tells me the T Con board has been discontinued. I have great sound but no picture at all anymore. Help
