How do i remove the green haze

one of two issues are possible here:Model indicated has a convergence circuit= colors are skewed or even 3d looking is convergence problem. Set has Akai name but is made by Samsung--if a convergence issue can be a do it yourself repair.I can explain what is needed if that is the problem (see some attached photos).The other issue seen is if on a black and white picture (color turned off) stand back and look at the screen= is it yellow looking or gray?If yellow looking the Glycol (a cooling fluid in each tube) is contaminated- usually in these sets the blue is first= no real blue leaves a yellow screen.Look at the photos and try to tell me which issue you have. 4_1_2012_6_39_23_pm.jpg4_1_2012_6_39_46_pm.jpg4_1_2012_6_40_11_pm.jpg

My 52 inch akai i bought used at a lawn sale now

If it is simply a matter of the colors not lining up it may just need the convergence adjusted, but if one color is missing altogether (sounds like maybe blue is gone) one of the CRTs might be faulty. If this is the case then it will be more expensive to fix than it is worth. Even though Akai made high quality audio products in the 70s and continues to make quality recording anf musical equipment the fact is that their TVs are very low quality I am afraid.

Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Below are more details for both items. Also, complete repair kits with instructions and repair support are avail from site such as www.TvRepairKits.com

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.

My tv does not come


The power supply board is dead, do you know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

Hoping this help to solve the problem...

This indicates a fault on the Power Supply.

Do you have the technical ability and equipment to open the unit and look at replacing PCB components that could have failed?
