Video distortion


You need to take your tv in and have the picture deflector re-aligned.  This doesn't cost much, My dad had to do that to his a few months ago and it cost 30 bucks.

MODEL NO SP42W4HB PICTURE DISTORTED TOP AND RIGHT SIDE COLOURED SHADOWS COLOURED WAVY LINES TOP THIRD SCREEN PINK AND GREEN


This is most likely a convergence problem. You should see 2 large black ICs in side attached to a heatsink. They will be marked STK392-010. Try resoldering the pins on these ICs first. If that does not resolve the problem, replace them. These parts will be about $20 each.
Keep us posted.

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.

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.
