I was 'gifted' with an Insignia home theater unit [dvd player and amp in single unit] Model IS-HTIB101071 dated May 2005. Friend said unit was dead. I opened it and found main fuse blown [F1]. D4 diode [1N5406] shorted. It's full of samxon 85C GF and GR series caps. I'm planning on replacing all 4 diodes and a full recap with panny FC's. It looks like the board got hot around the diodes.
