Question about Akai PTH5498 54" Rear Projection HDTV-Ready Television

4 Answers

Akai PTH5498 54in, red and blue all over the place.

I have double images, and the red and blue are all mixed up, I tried setting the Red Convergence but nothing happens, the book says to use the remote, but when I try this nothing moves. I can?t set the Red or the blue. Is there a problem with the convergence not working? This just started this, and now I have no way of setting the convergence. Any help will be greatly appreciated Thanks Pete

I have seen this problem before. Look at the convergence amp. section of the set. at the bottom of the heat sinks . there are 1 fuse at the bottom of each on the board they look like resistors they are 3.5 amp fuses, i believe, that blow. no way to tell except with a meter. try this first if it works you got it, if not truy replacing the amplifier ic's and fuses again if they blow. Good luck

If you cannot correct the problem in the customer conv adj menu, or by pressing an auto focus button, then you have a defect in the convergence circuit...don't attempt to enter the service menu (the other guy has incorrect info) You'll only make the repair more difficult for the trained technician...Good Luck

I had the same problem. you have to type in a code to bring the color grid up then adjust them left right up or down...But I lost the code and i need to do it again. So if anyone knows the code it will help us all out. It was something like mute-0-8 then click 7 for red and so on but I cant remember. I got the info from a downloadable repair manual it was very is to understand and read.

Double image and 3d color


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.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

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. Power light will blink. 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. And you should be able to get the grid straight.

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 fix

Samsung HCM5525W TV red blue outlines on images


The Samsung has bad convergence IC's most likly. This should be repair ONLY by a trained technician as a TV set is not a place to experiment or tinker with because of the extremly high voltage inside. This repair should cost you in the range of 250 to 400 bucks . Good Luck
