Question about Hitachi 51GWX20B 51" Rear Projection Television

1 Answer

Hitachi 51GWX Scrambled Picture

Our HDTV picture suddenly went haywire - multicolored horizontal lines that move vertically across the screen - no recognizable picture. If this was an old tube TV, I would reach for the vertical hold control. It is the same for all input sources. The TV menus are recognizable but also are effected by horizontal dark lines that flow vertically.

Owners manual doesn't help at all with identifying the issue. What is up?

Line across middle of screen, rest of screen black


The problelm is a defective vertical deflection system. Could be the amplifier, vertical output driver or whole printed board that supports the vertical deflection activity. It is considered to be a serious failure.
The cost of repair will be around $200 to $300.

No picture or just one line across screen on hitachi ultravision rearproj.


Could be a loose connection on the printed circuit board in the Vertical deflection circuit.
You would have to have a qualified technician to repair this problem.
A intermittent connection in the circuit described can cause a horizonal line across the screen.
You have to be careful and not leave the TV on for a period of time with a bright line, as it can actually burn a line on the CRT screens, which is permanent.

Hitachi 51SWX20B Convergence problem


Solution:

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.
