Hello Techs, This unit came in with Q600 and Q601 shoted and R615 open. I replaced these to no avail , the self diagnostics blink 5 times. I have replaced IC 600, IC707 and Ic561. The 7 volt standby is OK but none of the others even try to start. Has anyone seen this problem? Thank You, Barry MacInnes Television Service Clinic W.
