    I have severe double imaging on my screen. Please provide a solution. Looks like gun alignment. How can I re-converge since the "Magic Focus" has rtun out of tricks. It appears to be the blue gun primarily at fault.

    i have a 2002 hitachi ultravision hd projection tv. everything works
    except the pic has a blurred double image. i've been told it could be a
    convergance problem. and it would cost about $200 to fix it. if that is
    the case would it even be worth fixing? i just don't want to take it
    some place and get screwed cause i'm a female.

T
your convergence ic's are Shorted

They have a kit for this tv it is available through local parts distributors
If you can't find it locally just Google HITACHI CONVERGENCE KIT

If you are not good with de-soldering and soldering do not attempt this repair. Remember to replace all the resistors in the kit

If you are not sure about doing this repair you should have your local tv guy do it for you

Picture has shadows with different colors (red, yellow, green)


Sounds like the convergence needs adjustment. You can do this through the menu-follow the on screen instructions. The idea is to line up the red, green, & blue.

Red color not lined up


You can try making adjustments to the convergence in the user menu. If they still will not line up you will need to have the convergence ICs replaces along with a few resistors in the convergence circuit. Fairly common in many rear projection TVs.

Blue and Yellow shadows


Google "HItachi Convergence Circuit" and you will see that it is a very common problem. Looks like TV repair guys get $400 to fix it. The parts will set you back $15-$50 but there is some complicated soldering to do.

I am going to repair my own...but I have a lot of experience in soldering
