Re: Misaligned Convergence

Is anenvolved job to repair a convergence problem,the way to go about it is to locate the convergence amplifier IC's,one for each color(red green,blue)check for loose conections at the ic's legs,after resoldering all the legs see if an improvement is present if it gets better you will be able to adjust from the custumer controls,but if no improvement the Ic's will have to be replaced.Some units have a separete board were you can adjust convergence after replacing the Ic's and other units you have to access the service menu to be able to do the adjustments but just doing this adjustments can be very challeging even for a train technician,I would suggest you seek assistance from a servicer and get an estimate.

Color is misaligned on our philips sspp9401 rear projection tv how do you adjust it?

Your problem is called CONVERGENCE. Look at the manual and you will find some commands on your remote that will automatically adjust the convergence to make the picture sharp. If that does not work, your television is unfortunately, in all probability...toast. Replacing the amps will cost what you would probably spend on a new TV. At the cost of flat screens today, you should jettison that old Phillips and break down to get an LCD flatscreen. Good luck. I have the EXACT SAME 55 inch TV...and LOVED IT...but at 700 to fix it...I donated it to a church and took the write off.

My t.v. picture was coming i ghost shade why?

If you are using antennae check the direction. If this is a cable input , then with a DVD , if all these show a ghost image, then the convergence of the TV section must be checked. Possible fault in the picture processing -( Y amp luminance)can lead to ghost images.

A ghost blue color and it will no line up with the white cross.

The convergence circuit for the blue tube has failed. You have 2 options:
1 - you buy a repair kit and you fix it yourself -
2 - you take the tv to a repair shop and they will replace the entire convergence board for at least $250

Projection TV2_bing.gif sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV 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, Samsung2_bing.gif, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith2_bing.gif, and others. You can get a convergenece repair kit from the link below.

Common Symptoms include....
  • Screen looks 3D2_bing.gif
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on - TV may also make a chirping noise.
Here are some photos of convergence problems.


Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash2_bing.gif focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a solution


You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from

Toshiba 57H82 entire screen flickers. Not clear. mult images

Take the television back to where you bought it and maybe they might repair it or swap it. It sounds like a defect in the TV.

BUT! Are you sure that its not just the aerial signal??

The picture has a double image.

All conections to the set need to be check very carefully starting form the cable to comes into the cable box from the outside and the cable that goes from the box to the tv,eliminate the cable box and conect the wire from outside direct in the tv and and see how it looks bring a small portable and conect the cable to it to see how it looks,once all the possibilities have eliminated then consider a problem inside the tv in the tuner area starting at the very conector where the cable conects.All this can help if the double image is not related to misaligned convergence.
