Bought a Sony DAV-S800 a month ago and on the whole have been pleased with it. However I have noticed an annoying fault? with it. After 20 -30 seconds the picture will increase in brightness then after another 20-30 secs the picture will dim down again. This cycle continues constanly. The increase / decrease is small but enough to make your eyes readjust and like anything when you notice something you can't help but look out for it, to the point that my viewing experience is being affected by it. I am using a standard S-video cable to connect it to my Toshiba 2505db 25" 4:3 tv. Anyone have any ideas if it is a player fault or down to quality of cable? Any advice appriceated kovo.
