Red Lens off on Hitachi projection tv Model 43FDX01B

I have tried everything I can now! My hitachi TV has a problem I can't align the red lens with the blue and green lens. The problem is the Red lens is shifted too far left of center. i can't adjust it with the standard convergence adjustment on the tv. Therefore I am getting a double image. I love this TV but it's really bad. I need help otherwise it's going to get trashed.

You should rotate the purity rings untill it has shifted into the proper place.

Re: Red Lens off on Hitachi projection tv Model 43FDX01B

I had a toshiba like that where the digital convergence didn't get close enough. Worse case scenario - remote the screen and loosen the red crt (don't loosen lens for there is liquid coolant in there) and put a couple washers under it and reinsert the bolt or screw. Worked for me and saved a TV from the landfill!!

Color has changed to green tint

    According to the system the problem in your projection is convergence and the solution is to replace the IC STK's.The part Number is CZ01341. Change the IC STK both and your TV work fine again.And for parts please see the link below.

The red and green convergence are not in sync

Projection TV sets have several common problems listed below.

Problem #1) Convergence


  • Screen Looks 3-D
  • Colors wont align
  • Screen may look distorted
  • No Audio/Video - makes a chirping sound.

Lot of red streaks across screen.Try to adjust convergance, blue aligned perfect but the red didn't

possible fuse. if the red is curved or bent, if the red is straight try covering tv with blanket so the sensors get a good reading. again if the red is bent, and fuses are good..... bad convergence ic's.... local service center

Red and green waves...double vision 43FDX01B

Try adjusting the convergence. If it won't move see below- (or hitting Magic Focus for some Hitachi’s)

This sounds like convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually $200-$400 Be sure to vote/rate me if this helped Thanks!
