it could be that the tv convergence circuit is going bad. One shure way of finding out is to go to the tv feature menu(picture,audio etc.) and select the customer convergence setting, you should get a cross hair pattern(cross in middle of screen). that cross should be white and by aligning the red or blue colors they should move left, right, up or down

Fungus in blue crt Akai rear projection

I don't have a pdf file for fungus in an akai, but you will need to remove the 2 tubes from the set, take off the cover for the reservoir and dump out the fluids and then fill them back up. you will then need to know how to do the convergence alignment after you put the tubes back in. This is a involved process, if you want to tackle this on your own let me know and we will see what we can do.

Red and green wavy lines

If the distortion that you see can be described as somewhat of a 3-D picture, the problem is teh convergence circuit and this can be fixed easily. Also, if you can solder, you can fix this yourself. If you wish to do this, please update this and I'll provide you with some instructions.

TV problem

If you cannot converge the red and blue back to the green through the convergence menu, Then you have worn out convergence ICs you will need 2 of them at about 10.00 each. Takes about an hour to remove the old and replace with new ones, but also check the resistors right next to the ICs usually 1 or 2 of these burn out with the ICs. Let me know if you need more information.

Colors red and green overlap

Covergence is off... Check convergence and see which color will not move in the convergence settings... That is the STK that needs to be changed out...
