You need to adjust the Green Screen Drive Located on the Focus/Screen Control Block Their will be 3 on Top to adjust Focus to each Tube R/G/B and under it is 3 Controls to adjust Screen Drive to each Tube R/G/B . Cleaning the mirror and Top of Tube Lenses will help improve Picture also if they are Dirty. Control Block is Located behind Front Bottom Panel Pull it off and you should see it.

I have a HITACHI 60in. LCD rear projection tv (model 60v500). I'm getting 2 large oblong red areas in the center of the picture. Is this an adjustment?


Hi,it seems you are experimenting a light engine problem.This is how your tv works: http://www.youtube.com/watch?v=ZLLHnQ4y-wo So basically the 3 Lcd chips that create the colors and image is going bad and thats why you get that color discoloration.Contact Hitachi or look for your light engine online.God bless you and your house!

OUR HITACHI 50V500A HAS COLOR PROBLEMS WE MOVED IT


This is an LCD rear screen projection TV. There is a Red, Green and Blue LCD pallet that is mounted on what they call an X-cube. If all you are getting is Red and green then something happened to the blue pallet. Either the Ribbon connector came off or is loose or something worse. How hard did you mover it?
Another thought. How is it hooked up. If component then this may be the issue as component video connections are Red, Green and Blue. Just a thought.
Let me know.
Blessings always,

PICTURE NOT AS BRIGHT AS I WANT HAVE TRIED ALL . TV IS HD REAR PROJECTION . I HAVE TRIED ALL AJUSTMENTS,COLOR,TINT,FORMAT,SHARPNESS, BRIGHTNESS ETC. LAMP ONLY ONE YEAR OLD.


Unfortunately there are 2 IC's and a capacitor that can cause this set to be really dark. Without proper troubleshooting it is impossible to diagnose. Have a shop check it out for you. Thanks

the more the tv remains on the picture gets out of focus mainly in the midle of screen. Sure sounds like tv needs some light engine repair or replacement.

Green line running vertically along the edge of picture


If its a LCD projection TV (such as Sony Wega, Hitachi, Epson, Philips, and some Panasonic, some Mitsubishi), and the green image is in the whole screen or just one part as a blob or a line. Is most probably that one of your LCD Color Filters is damaged (burned out or starting to get busted), I don’t know if you can just replace the color filter, I believe you need to change the whole light engine system or the optical block. There are some places around, I found some on ebay but you should definitely try on discountdashmerchantdotcom their price range $260.00 - $330.00

Hitachi 52 projection tv


use the advanced options page and reset the factor blue and red convergence defaults then do re apply the auto color defaults color at first it seemed very red (which is good because red was the missing factor in the green picture) but after reseting all the color and tints to the normal ranges I then reset the color auto correct again and all seems fine.
