    came in with HOT shorted, HV cap in front of HOT burnt hole in board, some caps in power supply were bad(puffed out), changed all, fixed the hole, still no power. i have the manual. i troubled shoot all the way to IV400 on ssb, not geting horz drive signal, went through all voltage checks and flow charts, problem appears to be on ssb. has anyone ever successfully repaired the ssb? i thought about just changing the iv400, but i am not convinced it is the chip or something that is causing the chip to shutdown. the ssb is $300, customer of course cant afford that. anyhelp appreciate.
