Question about Sony KV-36XBR400 36" TV
I have a problem with a Sony KV-36XBR250 TV. I recently moved it and afterward, I found that I had sound but no picture. I can also change the channels. When I turn it on I get no static on the screen. The light on the bottom blinks continually. I have read that the blinking means. No reply from the jungle IC301 (data bus is busy, shorted to ground or held high), IK video path is defective. Does this mean that I should find IC301 and replace it. I think that it is on the ?B board?. (I have a service manual and schematics for the KV-36XBR 400). I left it unplugged for several hours and retried it with no luck. I have taken the back cover off and pressed down on some of the connectors hoping that something may have come loose while moving it. I had no luck with that either. The back of the tube does not turn orange when on. I really want to fix it myself. I don?t think that it is worth a large repair bill. What else can I try or replace? Which board should I look at first. I do have some electrical repair skills, a meter and a lot of patience. Help please.
Thanks, I had someone here fix the big board. It seems that when we lifted it with the hand truck we broke the board. The unit is so heavy it is hard to hand carry upstairs. The repair was just under $200.

New D board, the cheapest way out.
