Akai large screen T.V. color problems

Just yesterday our TV started having troubles, almost like tracers of some sort. For instance, when there is a face on the screen, next to it will be an outline of that face in blue. When the kids played video games the same thing happened. There is double of everything but it's only an outline, located an inch or two over from the origional picture and in blue. Does this mean my color os going out? Is there anything I can do to check it before having to pay to take it in. I'm not a TV mechanic in annnny way. Thanks a bunch!

I have a similar problem with my AKAI 42 inch plasma, now my whole tv is purple. all you can do is contact akai warranty and have a service provider come out. but let me tell you, it is not an easy process if the service provider cannot help you. after the service provider told me that my tv was a goner. it took me two months to get a box to then send the tv back to an akai service center. now i have to wait a month or so, before i get it back. i wish you good luck.

Akai 52" rear projection...colors are off and screen is washed yellow


Sounds like the blue gun has died. I would say that you should call Salvation Army and have them collect it for you and buy a new LED flat screen TV to replace it.

When I leave my TV plugged in too long the color goes out and everything is red. What causes this?


Depending on the age of the TV it sounds like its over heating after being on for a certain amount of time. If you can hear the tv start to make different noises/get louder over time then it would confirm the over heating. If it is over heating you can attempt to remove the back panel, or place the tv in a more ventilated area, or even place a little fan blowing into the back of it. A lot of large TV's can have over heating problems due to the large screen.

Hope this helped.

All projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.

Common Problem #1) Convergence has gone out

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 pics of convergence problems.

Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

You are going to have to look for open PICO fuses along with bad bias resistors close to the ic's. You should have close to +27 and -27 volts of B+ on the chips to start with. That will ensure the fuses are good. Then trouble shoot the convergence circuit from there.

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 Sony2_bing.gif,Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer2_bing.gif, Hitachi, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links below.

  • Screen Looks 3-D
  • Colors wont align
  • Screen may look distorted or warped
  • No Audio/Video - makes a chirping sound.

Hi I have TV AKAI start projecting a red


rear projection tv can be crt or dlp, if crt, try to adjust red color using the customer convergence feature, you will find it in the customer menu usually under advance feature or video settings, some tvs will just give the convergence caption right on the menu listing. If this does not help then the tv might be in need of some convergence circuit repair, probably one of the power outs is damages and needs to be replaced. If it is a dlp if the red shade extends all over the screen or located in a certain area of the screen then i would have the tech check for light engine trouble, this is a common problem on some dlp systems.if i answered your question satisfactorily please leave your positive feed back. thanks

My big screen tv show snow on all channels.


ok.

if you see only snow on the regular screen, might as well check the connecting antenna at the back since you mean all snow on all channels.

hope this helps.

Yes, you have a size problem you have horizontal and vertical size. Either its' in the service mode or somewhere on the set, with this set it's probably in menu. Must be set too high. I will look for menu codes! Is this an Akai or Panasonic set?
