Your convergence ICs need to be replaced. Its an easy job if you can solder. Let me know if you need any more info or a link to where you can order replacement ICs.

    It usually is. Some times its the circuitry that powers the ICs but 95% of the time its the ICs as they run at such high temperatures they are prone to failure on a regular bassis.

Your green gun in our tv is misagligned/out of focus. Your tv uses red, green and blue guns that layer in different shades and mix to create the different colors. Your green is a little off so the colors aren't mixing right which explains the green haze and the shadows. A tv repair man can fix this problem pretty easily and it isnt expenisve.

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
