Question about Hitachi 50FX48B 50" Rear Projection Television

1 Answer

Hitachi projection screen 98modle

My projection screen that I bought new Model # 50FX48B Vin# V8K015438 Chassis # AP62P 194W, 2.6A has a picture that is narrowing from top to bottom 10" from left edge. This of coarse causes the whole screen to be blurry.
1. removed back, cleaned out moths & other bugs from camera's.
2. placed paper plates over each camera and removed them one @ a time. narrowing was never affected. All camera's seem ok.
3. (marked all knobs first) tried adjusting the 50+ knobs on the pannel behind front speaker cover to ajust out narrowing. All I did was make the middle of the screen clear and the outside blurry...and vis versa. I could expand the projection, but really made no affect on narrowing problem.
4. Years ago I had a reset button installed so after black-outs and power blips all I had to do was reach in the back and push the small button 3 times and presto... everything was ok. button still installed.
5. I can only see one area all three cameras splice together and attach to a board. I am hoping yall know the name of that board and it is replaceable.

Thanks in advance

Have a 50fx48b Hitachi TV, screen flickers, gets wavy and goes to horizontal line, smack top of tv and it goes back to normal.

This problem is a couple of bad caps in the vertical and horizontal sweep area, just can't remember which. It use to be a 220uf cap that needs changing.

Have a 50fx48b Hitachi TV and screen flickers and then goes to small wavy horizontal line. smack tv and it goes back to normal.

If your TV looks 3D, warped, or distorted it likely has a convergenge problem.
If however it just looks dull, washed out, redish, greenish, or blueish or if it looks like objects on the screen have halos the fluid in the lens has soured.
You can search google for parts or you can get the parts with repair instructions from sites such as

Go to this link and click on the contact linkon the lower left side of the home page and leave the measurements of your screen top to bottom and side to side. They have used assemblies just measure what you see right up to the edge of the frame and they will add the extra 1/4 inch for whats inside the frame.
