Check pico fuses f9a04 and f9a05. They will prob be open. if so, repl conv ic's qty 2 stk392-570 . you will need pico fuses 5A heat compound, solder and iron. also check caps in dm module. if swollen, then repl. there's 4. 4700uf 50v i believe. Also check to see if there looks like something spilled on the circuit boards. if so, your picture tubes red/green or blue may be leaking coolant oily substance. If this is the case, try removing the pcb and cleaning with 97% alc. They make good cleaning sprays too. The boards may be shot. good luck to ya.
