Question about Sony STR-DE635 Receiver
My sony str-de635 led display goes dead after being on for several hours. Is there any fix for this as I am an electronics technician. Thanks
I suspect intermittent 31V supply, filament supply or bad connections on fluorescent display.
Check Q801 31V reg , R802, zener on base of Q801 located on DC board. Inspect all boards for bad solder joints, reflow and tighten pcb grounding screws.
