Question about Zenith IQB50M90W 50" Rear Projection Television

1 Answer

Bowing in the middle like an hour glass

The convergence was set and the picture looks very nice but every couple days the picture bows in the middle the picture is not streched. the picture that can be seen looks good. the viewing surface is wide at teh top and wide at the bottom buttom, but more narrow in the middle and the left side has distinct blue and green lines (thick) and the right side and thick distinct yellow and red lines. this problem goes away on its on and reappears on its own. and while it is gone the picture is perfect. thanks in advance

    update. i can kick the back of the set while it is bowed as described above and most of the time it will go back to normal. However sometimes i have to kick it several times.

OUCH!!!! Don't kick me...would be my response if I were your TV
Convergence amps problem.

If it works after a kick I'd say poor solder joints on the convergence amp leads

Picture problems


Is it one color that has moved? Sounds like a convergence problem. Find a channel with a fixed picture, or if you have digital cable or satellite pull up a guide, something with a straight line across the screen. You will likely see one of the colors is bowed or or shifted. You may be able to adjust that with your remote under the "convergence" adjustments in the menu. If it will not adjust it will need work done to the convergence circuit. Not a DIY project.

We have a Hitachi 53udx10b tv. Recently it was


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.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

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

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped or bowed
*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 Distortion


you have a convergence problem.. If you understand how this works then you can go into the set find the convergence ic's and replace them and sometimes you need to do some alighnment as well. Its always best though to let a service tech do a job like this as he will have all the proper equipment to adjust and troubleshoot the set Good luck
