I am unable to adjust the red color in the convergence adjustment on my IQC50H94W 2000 Zenith 50". From everything I read I believe I need to replace my Convergence IC Chips, however I am not 100%...


Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from www.TvRepairKits.com and do the repair yourself. Its a fairly easy DIY fix.

Samsung PCL542R the Timer light is on and TV will not turn on


TV is in shutdown, may be caused by a shorted convergence amp IC. Also could be caused by any short in secondary B+ supply. Unplug supply to converg amps, if TV comes on, but out of convergence then you have a shorted IC, STK-392-010

Mistubishi Convergence/video display problem


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,Pioneer 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

You can see some more examples and find a fix herebb0cf99.pnghttp://www.fixya.com/support/r2861467-solution_video_looking_whiteish_dull

If there is no high voltage and you changed converg. amps, then there are still fuses on converg side that could be bad. Also Horizontal output could be bad. If set is dead or just will not come on and has little sound. These could be 2 different problems.

MY ZENITH MODEL # Z60Z83R8 BOW'S VERTICALITY


You have a problem MOST LIKLY!!, that happens to almost if, not to all projection tube sets ever made. Its the old bad convergence IC falure. It's not something you can do unless you have had exstensive electronic training and soldering skills. There are no user replaceable parts inside of this set so please call out a pro to repalce the convergence IC for yop! A repair such as this should cost around 250 to 400 bucks, depending where you live..Good Luck
