Ur tv have a problems it call convergence,it dead.U must have soldering tools,solders,and know how to solders to solved convergence problems.U must replaced 2 STK convergence ICS and some or all it resistors.Tries websites like Tvrepairworld.com,Tvrepairkits.com to buy a convergence repair it ur self.The shop will cost $300-350 for the parts and labors.
sounds like the sensors are out of focus and your red sensor isnt turning on. look in the back of the tv for a master reset button or in your menu screen some sort of "Flash focus" or "convergence". They will realign the 3 sensors.
sounds as if your convergence needs to be set. either through the menu on the tv or remote you need to get to the convergence set screen and you need to line up the crosshairs. this usually happens when the tv is moved or bumped.
This is a convergence problem. Try resoldering the pins on the convergence ICs. These are large black ICs attached to a heatsink. They should have about 15 pins and be marked STKxxx. If the resoldering does not resolve the problem, replace the ICs. These should cost about $15-$25 each.
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
the convergence IC`s and associated resistors have to be replaced, do not repeatedly push magic focus or the alignment after the parts change out will take longer which of course means higher repair bill, good luck
