You have bad convergence IC,I'm afraid. You will need to have both of them replaced. this job should run you about 300 bucks or so to have them replaced and the set realigned. DO NOT try to adjust the convergence inside of the set before replacing the IC's, as this will only make the job cost you more. Good Luck

Hitachi LCD M50VS810 -- picture gradually darkened up over the past 4 days and now picture won't come on. Replace bulb?


If it uses a lamp that is possible---sets with a lamp will often dim down just before the lamp fails in a total way.

Green bulb-or lamp on ultravision hitachi 57uwx20b does not work how much to replace?


On a projection television you will have to replace all three(red,blue,green) projection guns in a matched set, the reason is if you replace just the green gun, your picture will be over saturated with green light making your picture look green,because the new gun will be alot brighter than the red and blue guns.
With that said, repair will cost approx.$400+, I've heard up to$600. Good luck !

Yellow and blue color ruins total picture on 50" tv,can't get rid


lupe0112,

I'm no expert, but I think that you have a problem with the convergence of the 3 color guns. I've been working on a similar problem. As a first step, have you tried "Magic Focus?" The Magic Focus button for the Hitachi 53UDX10B is at the left of the small front panel controls that also include your RCA composite and SVideo connectors. Let the set warm up for about 20 minutes (as recommended by the user guide), and then press the Magic Focus button. When you press the Magic focus button, the set will auto align the 3 color guns. If this doesn't fix your problem, unplug the TV for at least 4 hours and try again.

Projection TV red is drooping


Do an internet search on "Hitachi Convergence Circuit". This apparently happens all the time. TV repairmen charge about $400. Parts are less than $50 but you would have to be an expert at soldering electronics circuits to replace it yourself.

My TV had the Blue misalign instead of the Red. I ordered the kit #9 from http://www.bdent.com/search/part.jsp?partnum=KIT9

DO NOT ATTEMPT IF YOU DO NOT KNOW HOW TO SOLDER. YOU WILL PROBABLY RUIN YOUR TV.

Hitachi 50 rear projection


Just curious... since the Hitachi 50UX57B projection TV does not have any lamps in it, exactly which "lamp" did you replace? Did you actually replace the entire blue CRT itself?
