Hi guys, went on a call for a mits that's in shutdown, found the set will remain on if in an unused video input or if the pix is a dark scene. traced the shutdown to the x-ray protect ckt. IC5A01 is triggering from pin 1, found tracing back to the flyback pin 8 at low bright or no video pin remains at 6.5 volts, pressing the menu changes this voltage to 2.5 volts and causes shutdown. I have checked All the common tips D5A22, D5A09, D5A21 and all the transistors around the HV monitoring ckt. Wondering if anyone had a bad flyback cause this symptom as I believe the flyback is bad. thanks Tony Saracco TCS ELECTRONICS 406 Andra Ct.
