Question about Zenith IQB50M90W 50" Rear Projection Television

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.

Convergence amps problem.

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

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

I have a JVC 48' widescreen tv approx. 7 - 8 yrs old. the picture is now extremely bad all of the colors seem to be out of wack and the picture bows inward toward the middle at the top and bows inward...

There's a miror or one like this might have a ''aluminium sheet'' miror.
Open the upper back cover to see what going on there, pretty sure something run out of place...

Problem with convergence

Try re-soldering the circuit board that contains the STK convergence modules. They're on the center circuit board attached to an aluminum heat sink that's about 8" long and 6" tall, about dead center in the circuit board. You may be able to recreate the problem (hour glass effect) by gently moving the heat sink (which the modules are connected to). This gives the hour glass effect on the picture and the advanced convergence screen. This is an indication that the modules pins aren't solidly connected (meaning soldered) properly. Remove the circuit board and clean the old solder off & resolder the modules pins to the circuit board reconnected the board and then retest by again pushing on the heat sink. This is a caused by a minimum effort (a.k.a. minimum cost) solder job, probably done in some 3rd world sweat shop. The "factory" job was good enough for 3-4 years but the heat (and these modules do create a lot of heat) and stress created from repeated use eventually takes it's toll, weakens the pin connections and our problem occurs. take the appropriate cautions working around the high voltage of the set & use a non-conduting piece of wood to push the heat sink when we doing tests. Best of luck, hope ya fix it.

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
