Here some info what to do before sending it to the shop
Open the back cover, check while the ptv is on if it is arking, I would suspect bad horzontal flyback, this would difenatly cause this,
Another issure is this the last person before you play inside the ptv on the focus block or tampered with the crt, well don't this is the worse move you can do.
Does it look like or tring to explain it is not our of focus but out of alinment, well is so your totaly in for a different ball game, it is convergence problem, this or the two big ship's that everyone just loves so deapely that they just want to scream, this ic's again or assesabel by the back only and has the part % starting with STK , if the picuture is diffenatly out of focus then this is not your problem.

Last take a long coffe brake and try by alimating what could cause this, I can almost garranty if it is out of focus then I would suspect the horizontal transformer you should know by the noise it is making, arking.

If you need more info just recontact me

Color shadowing on screen


I had similar symptoms about a year ago. Also came on sudden. The red convergence chip had burned out (poor heat sinking on this model Hitachi). Replacing the color convergence chips fixed it. ($50 for parts.) First, however, have you tried the "magic focus" function? That's explained in the manual, which is available online IIRC, but I'd have to look for the link if you need it.

Color red seems to be more prominant...than other


I've had this problem with my projection TV recently. I would say your lens/lamp is to blame. It might be time to change it, depends on the last time it was changed, most of the time, the TV will tell you that it needs to be changed, but not always. I think your best bet is the TV lamp.

My picture is shadowing itself like dual images and the colors seem to be separating, like the red from green. Is this repairable and is it worth it?


Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projeciton sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you are handy and can follow directions. You can get complete repair kits from TvRepairKits.com or click here. They have put together DIY repair kits that include the OEM parts and step by step photo instructions for each repair. If you are not handy or can't follow directions we would suggest calling a shop.

Your green gun in our tv is misagligned/out of focus. Your tv uses red, green and blue guns that layer in different shades and mix to create the different colors. Your green is a little off so the colors aren't mixing right which explains the green haze and the shadows. A tv repair man can fix this problem pretty easily and it isnt expenisve.

Focus problem


If it's under warranty call the manufacturer, in every case I've seen this it turns out to be the Optical Engine. Which can be a very expensive part to replace not to mention quite labor intensive. but it definitely sounds like the OE is dead or not calibrating properly.
