Sounds like a classic convergence problem. most likely bad connections on the bottom of the stk's. If a repairman were to do this for you it would run $300-$500, if you were to do it yourself it would run less than $100. Bad connection on the vertical IC can cause something simular to this as well. If you need more help or would like to fix it on your own please let me know

We have a 1998 Toshiba tv. Its a 50" screen with


Hi,

This is an indication of out-of-regulation in the power supply section. This is cause by leaky/dried electrolytic capacitor in that section. It will dropped the supply from normal voltage and will disable the unit.It needs a little warm-up to make itself stable but the symptom will get worst until the unit will not even power up. Sometimes it has a bulged/dome at the top but not all, it is better that you have acapacitor checker/tester to determine its condition. Your unit will back to normal again if the leaky/dried capacitor is isolated. If you don't have a capacitor checker, replace all electrolytic capacitor in the power supply section, it will not cost you much because this is one of the cheapest part on that board. Watch this video for more info regarding electrolytic capacitor.

If you don't have necessary tools and test instruments, and can't do the job yourself, I would advice you to look for a professional to troubleshoot the problem. Don't attempt to work in the power supply if you don't know the safety precaution of handling it, there some stored electricity enough to hurt you with a little mistake only.

Hope I helped you.

Have a nice day!

Thanks for using Fixya.

Red green and blue colors do not overlap. Looks like a 3d movie without the glasses


Projection TV's sometimes need a "Convergence" adjustment. If you do not have the manual and/or cannot find the option in your TV menu, here is a link to help. Follow up and confirm this was your problem.

Have colard shadows hit side of tv comes back in focus


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

Alot of rear projection t.v.'s have a convergence option in the menu on the t.v. There you can set the try to set the colors back how their supposed to. Mine has a cross in the middle of the screen and you just have to try to get all 3 colors to line up. Unfortunately, the actual lens inside mine has to be aligned so it doesnt work. Just something to try though, hope it helps.

Strong colors, specifically those in the red


it seems you are experimenting a light engine problem.This is how your tv works: http://www.youtube.com/watch?v=ZLLHnQ4y-wo So basically the 3 Lcd chips that create the colors and image is going bad and thats why you get that color discoloration.Contact maker or look for your light engine online.

Looks like watching 3D movie(colors) and rounded


This is a convergence problem and is either bad connections on the convergence ICs or defective ICs. If you feel that you can solder, you should be able to repair this yourself. First try resoldering the pins on the convergence ICs. If that fails, replace the ICs. These ICs are large black ICs attached to a heatsink and should be marked STKxxx.
Keep us posted.
