We have a Hitachi projection tv maybe 54" that worked fine yesterday but today has shadowing/ghosting in pink & green. Wondering if there's something easy to try to fix? If not, is it worth getting it...


The most likely cause is shorted convergence chips and possibly a few pico fuses.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony,Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer2_bing.gif Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2
Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Picture is OK, but colors are off and there is a blue star background that shows on dark colors.


Hello, With most rear projections there is usually an alignment to do with the set up with your TV. This is so the red, blue and green projectors align together to give the correct colouring. This sounds to me what may be causing the outlining of the blue. This can also make it seem off colour. Look in the set up menu of the tv and see if you can find this alignment feature. Usually a cross will appear and you move a blue, red, and green cross with the arrows on your remote to align over the original white one. If this does not work, it may also mean that one of your projectors, that is the red, blue or green one may be failing causing the off colouring. Hopefully this alignment may fix it for you.

Color Alignment


the most common problem when the tv felt is the shadows all over the screen (maybe the tv didnt show it imm but looks like now is there the problem)
second:there is a circuit in the tv that works when the tv turns on every day. prevents the tv showing shadows on the screen.
the answer is this: if that system that prevents shadowing is working then the CRT is broken and say bye to the TV. But if the expert tech can make sure the D' gauss system is not working and can repair it then you get tv back.

Arched pink lines across screen. Now green and pink double stacked wording.


Projection sets have two very common problems.

The first common problem is convergence


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.

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.

IM HAVING A SLIGHT PROBLEM


You need service. Sounds like the convergence is out of adjustment. As the picture is formed by a tri- gun arrangement (one for each colour), if any of them is not correctly aligned, you will see shadows on any sharp line like text, or blurring on a picture. The shadow or blurring will often be one colour i e. red, blue or green.
