8 blinks in KLV-32S400A shows Audio Error
Check audio voltage supply from power supply board, if OK, replace GP Board (main board)
and if audio volts are not available, check/ replace power supply board.

This seems like a T-con board problem as its responsible for several picture functions including color convergence. Or it could be a bad LVDS cable (inside the TV) I can ship you a new T-caon board for $150.00 or take it too your local shop repair shouldn't cost more than $250.00....
