Question about Mitsubishi WS-55513 55" Rear Projection HDTV
On the signal board there are 4 surface mount transistors. I would replace them all but the culprit is probably is a transistor on the lower right of the signal board ( BA06) its right next to the input board, check the caps close to them also. If you look closely you will probably see cold solder and flux around it and the board will look browned there. This transistor when bad you will get wavy lines on the screen and they will go away after 3 min or so. It it has totally failed the set will come on and you will get no picture, but the OSD will work fine.

board problem = less $ and easier to sub than signal PCB.......T.
