I just recently bought a replacement 9200 with a s2 plus board off ebay. It works fine other than a quick flicker on occasion on the bottom half of the tv screen which looks like color bars or a test pattern. It is only there for a fraction of a second. It is gone so fast I can barely describe what it is. I know there are some heat concerns with the 9200 with the board installed. Anyone ever seen or heard of this? My dead 9200 never did this with the standard s2 board installed.
