Question about Hitachi 51SWX20B 51" Rear Projection Television
I hope someone can help.
My 51SWX20B has been a great TV but all of the sudden the convergence went out. The horizontal convergence lines are fine but vertical lines are really weird, I run the 'Magic Focus" and it appears to run normally and horizontal lines are still fine and looking in the exact center (vertically) in the screen, as you go out to the right the red is pushed out to the right and the green even further, to the left of center the red is pushed left and the green farther to the left. The horizontal convergence is fine. I can manually tweak it back into place but they all interac t and it's a pain and there are major distortions on the edges of the picture.
Your TV has a convergence problem. Here are some of the most common symptoms.
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.
