    What are ICs? Can a layperson open up the tv and replace them? What does it usually cost?


  • Mthorn Nov 20, 2007

    The tv guy came and said that it is the red lamp and it would cost too much to replace for the part and the service. He said that there was a glob of something in the red lamp.

    Any opinions?

  • Mthorn Nov 20, 2007

    Thats good to hear but my dilemma is that this tech was the Samsung contact. He says it is not worth repairing and since it is 3 yrs and 2months old it's not covered.

    It seems that my only choice is to buy a new tv during the holiday season....

  • Mthorn Nov 20, 2007

    Sadly this is the person approved by Samsung. He feels it would be too costly to repair. It's hard to find anyone in my area. It seems that all I can do is buy a new tv. Mine is now 3 year and 2 months it is out of warranty.

    Obvious "the tv guy" is not a senior technician........

    If there was a "glob of something" in the red lamp,how is it possible to have linear double-images?? Wouldn't you see an

    effect equal to the blob of something ??The truth is often based on logic and reasoning.....Please consider = self-employed,

    your disposal here at Fixya! Our mission/compensation??

Akai rear projection tv...picture is not deformed....however there are images (Ghost image) in separated 3d

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

Akai 55

I used" Silerado 1st" solution. I have an Akai pt5598hdix/sms.
I had ghosting.Like 3 colors side by side.
Silerado said with TV off press "mute,1,8,2" then TV on.
I didn't see anything like a menu.He warned to write down any setting you saw before you change anything.But for me nothing came up. So as he said the next step try with TV "on" press "Mute,1,8,3" this is another set of adjustments for finer detail. I lined/overlapped all the lines up or down or side to side useing the channel and the volume buttons and then held the enter button down until the TV flashed 3 times.Then I shut it off and when I turned it back on It was perfect.

Your set has what is know as "convergence problem" because of the bowed lines and ghost in different colors,is really not an easy solution,the set should have 3 amplifiers(one for each color)and they need to be replaced with an exact replacement,sometimes just by replacing them the aligment should be close but soemtimes you nned to get into the service menu to do some adjustments,the amps(IC's) are mounted on heat sinks and all 3 have the same part number on its face,they normally read STK--- ---,every set uses different amps,If you are familiar with tv service you have now a place to start working but if you are not too familiar be safe and call for help from a servicer.Let Us know if you need more information.
