Free TV I just got a TV for free. It is a Hitachi Ultrascan HD. The picture is only red, a wavy picture, and it is missing picture in the top right corner like a piece of broken glass.

It probably has a broken mirror or somethings inside the set blocking part of the pic. Now for ther picture all red. If your not a tech I highly advise you going insidew this . Unless you know about the saftey issues and the HI voltage issues. Your problem could be a shorted Picture tube all the way to na bad distribution block . Good Luck

Tv suddenly started being blurry with red double images real bad in top half of screen. its a hitachi ultrascan hd about 10 yrs old.

You need the convergence ICs replaced they are soldered in so its very technical , a repair shop will charge between $230 and $400 to replace them. you can try the autofocus or manual adjustments, but probably need the ICs and possibly a few resistors too.
(2)STK392-110 or kit # X480293 comes with 2 ICs and some resistors

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.

I am told my Hitachi 61SDX01B (UltraVision/Ultrascan) has "Green Geometry"

Sounds like a convergence promblem.

Here are some of the most common symptoms of a convergence problem.

Screen looks 3D
One or more colors can't be adjusted when using the convergence menu.
Screen is bowed in or warped.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence or magic focus section.

Try to adjust the convergence.

You should be able to move them up, down, left, and right.

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

Its a fairly easy fix on the Hitachi sets.

You can get a repair kit that includes all the parts from www.TvRepairKits.com. The kit includes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc.
Everything you need to fix it yourself.

Hitachi 61SDX01B

The problem is called green geometry.There is nothing wrong w/the green pix tube.It is critical to get the green geometry

accurate because the red and blue convergence overlays on

the green.If you have more than an alignment issue,that will need

repair before adjustments are attempted.
