The red and blue convergence ICs are bad. Probably only the red one is bad, but you should change both to be sure the other doesn't go out the following week. Go to tritronicsinc.com for the the replacement chips. The chips should be installed by someone with soldering experience as they have about 20 pins each.

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. Repair kits with instructions are also avail from 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 t.v.focus is like double vision and the color is not right.


convergence failure that tv has 3 CRTs-cathode ray tube- and it has a circuit that keeps each picture projected from the tubes aligned together called convergence. so if you have a picture that has 3 pictures of the same image in red green and blue then it is defintely a convergence failure. the part numbers of the parts causing the failure are STK394-160 and there also can be some burnt resistors in the same circuit.

Picture Problem!! and its not convergence (Double vision except for middle of screen)


Could be pin correction circuit or your picture tubes could be worn out . Sometimes when the crt's get weak the edges seem not as clear as the center of the screen . Give model number if you think the pin correction may be your problem but, the tv is pretty old and avg. life for them is 12 to 15 years when the picture tubes start to degrade . Good luck

Double- Vision


More than likely your akai has defective stk392-040 Convergence chips . it also may have open resistors generally 3.9 ohm flame proff. this board is attached to the top left looking from the back of the set it is screwed on by 1 screw black in the center . after installation this will probably half to be converged dinamically. which means you will half to get to the grid this is done by using the remote press mute 183 quicly to enter numbers on thew remote 2 to adjust red 4 to adjust blue horizonta 6 to adjustred vertical and 8 to adjust red vertical using center button to go up and down

No its a tube and not a bulb. If thew line is green then theres an issue with the red and blue as the green is stationary on most sets unless thers a green centering ? Its a componet on the convergence board thats bad or going bad but if you replace any components on the board most likly your gonna need to do a convergence alighnment I would let a pro handle this repair unless your an experineced repair tech Good Luck
