Mom called with a Sony TV problem. Pressing local start causes relay to click and thats it!.No picture...no sound. Noticed that when set was unplugged , could hear degauss circuit go active when plug was reinserted. Also noted that remote will not turn TV on but if local on button is depressed and relay clicks, then remote can deenergize start relay. Any idea's.....cheaper to by mom a new set?? Thanks
