Question about Hitachi 50V720 Television

Blue Cloud in center of tv after changing bulb

A large blue cloud appeared in the center of my picture approximately 1 month after replacing the lamp. I read on a Sony blog site that I could remove the rear panel and just adjust the blue knob. Is this true? Also, where can I find a diagram on how to remove the rear panel?

id guess your set is like a 50v500 or 50v720 its a lcd rear projection
the blue cloud come from a warped lcd plate in the optic engine and would require replacment to correct this problem
if you have a extended warranty you would want to contact them
if not you might contact hitachi consumer affairs and ask them if there would be any assistance with this repair

Blue area near center of screen


Uh Oh! blue screen of death. Your light engine has warped a little from overheating and is distorting the picture.

My suggestion to you is to get on the phone with hitachi and start complaining, then keep complaining until they agree to pay for it. You may have to get the problem diagnosed by a pro before they agree to pay for it though.

Check the optical block repair at sony's warranty website...
Could be the problem they have been covering it under a recall of sorts. $1250 for the optical block and they are only doing it until the end of the year so don't waste any time
