Question about Hitachi 53UDX10B 53" Rear Projection Television
Hi, I was given a Hitachi 50UX22BA. It has a very dim/dark/shadowy picture. However, if I stand in front of it, at just the right angle, I can see a picture through the middle. Although the picture is grainy and saturated with strange color. Could this be the convergence problem that many of the Hitachi have? Also the sound and the remote is not working. Not sure if it is related. By the way, I checked for any bad or bulging caps, but all look good.
Well excuse me but if you got the esquematic lets analyse this problem, first we got signal(you can see the picture) if got picture the sound signal is there (they tavel both the same way audio in a sub)then we got swept both vertical & horizontal (you see the picture) what we dont have? asignal amp,(thats the snow) good control of the 3 canyon so thats a comun problem for all 3 canyon, then we have to check for voltage reading in video amplifire it are not working ok and check for a leak capacitor in coupling circuit in the amp circuit what else ? did I over pass something? hope help you ...good luck... post back
