    I do have the correct remote for this. I have done the self focus but nothing is happening.

  • joshy621 Jan 31, 2010

    The red is really off and it bows down from the top and bows up from the bottom. How can I adjust this.

  • joshy621 Feb 01, 2010

    Yeah it looks like the top picture. The model number is: 5299HD. Where can I order these from and about what do they run for price. Is this something that I can install on my own?

If it is an Akai it was made by Samsung----and it should have two ways to adjust convergence-----both require a working original remote for this to be done.

If you do not have the correct remote almost any Samsung remote will work in the customer menu.

Confirm actual model number on the back of the set and if you have the correct remote---

IF convergence will not adjust in the customer or tech mode you have a problem in the convergence circuit.

Let me know what you do or do not have.

    In the customer menu there should be a setting for CONVERGENCE, it will allow you to attempt to adjust the convergence at 9 points on the screen. Is the model number indicated the correct one for this set?

    Entry into the tech convergence mode should be mute, 183 but if it will not adjust in some way in the customer menu--it will not adjust in the tech menu.

    If it is bowed like in the photos attached---one of the two convergence IC chips this set uses is bad. Both chips and any protection parts taken out would have to be replaced. Confirm actual model number on the set and I will tell you which chips it uses.

    That model shows as using Two of the STK 394-250 convergence chips---depends if you can locate them inside the set and get at them--each is soldered in and has 18 pins---there are sellers on Ebay that have them for about 10 dollars each---local places will get 2 or 3 times that for them.

    It can be a do it yourself job but this model is not the most easy to do this on.


    If you want general instructions----take a good digital photo of the inside of the set and post it here for me to see so I can tell which version you have and direct you as to how hard it will be and what you will need etc.

Horizontally the picture is distorted (doubled). Sound is ok. we have a 52 inch RCA big screen tv.


Projection TV 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, Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit from the link below.

Common Symptoms include....
  • Screen looks 3D
  • 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 flash 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 www.TvRepairKits.com

You have a problem with convergence and all you may need to do is replace a fuse. Look up convergence for your tv model and hopefully you will get an answer as to where the fuse is located and how to replace it. Very common for RCA tv's
