Double images and bright pink and green colors


Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded over.

Green and pink double vision on my tv


This is a convergence problem. Try resoldering the pins on the convergence ICs. These are large black ICs attached to a heatsink. They should have about 15 pins and be marked STKxxx. If the resoldering does not resolve the problem, replace the ICs. These should cost about $15-$25 each.

Hitachi ultrascan hd 42 in


The problem you are facing is a common problem in all rear projection TVs. It's called convergence. If you go into your menu there is an adjustment for it. if it doesn't move back into alignment then you have a more serious problem in the convergence circuit which will require replacement of components.

Ultrascan hitachi 43" hd tv


Marcus,
What you're describing is convergence and the amps need to be replaced... IK04 and Ik05 are two STK392-110 and Hitachi suggests replacing them with the STK392-150's for greater reliability..
If you're not too capable in electronics this is one to leave for the professionals. But at least you can call around and ask what each shop charges for replacing the convergence amps in this unit...
Hope this helps.
