My husband & I have a Sony Rear Projection. The green color was off and we replaced both ICs. We had a professional solder them and double checked the connections.
And now we have a blank screen. No picture whatsoever. The light does blink and I read somewhere that this can help diagnose the problem. We have 8 blinks when we turn it on. Then four quick blinks and approx. 2 seconds of nothing. Then four blinks again, nothing, etc. What does the four quick blinks mean. Should we just be junking the TV at this point?
Thanks for any and all help you may give us! You have all been so helpful!

Okay, I thought to look at my service manual (duh). And the four quick blinks supposedly means that vertical defection has stopped. It says that one of the reasons could be the +/- 15V is the D Board. Any ideas of how to fix this? Thanks!
double check all connectors you unpluged to get at the ic's you had replaced, very common to get them pluged in wrong spot or not at all.
