Question about Sony KP-53S25 53" Rear Projection Television
This unit has CRTs and does not have a lamp. Most likely you have a problem in the high voltage section. This can be checked with my tip at http://www.fixya.com/support/r4916941-diagnose_repair_projection_tv_high which explains the problem although it was written with a dead set in mind. It also tells you where to get the best price on parts. There is an outside chance that you could have a video drive issue. This problem would be on the other board (not the board with the high voltage). There really isn't a way for you to troubleshoot this board. If you do not find any problems in the high voltage circuit I would replace the small signal board. Available from http://www.encompass.com.
Thanks for using FixYa and for the generous rating.
