Have a akai tv that's has a green or yellow tint

Check the picture tube base card for any loose solderings. Your TV lacks Blue colour putput. Check all the solder points on this board. Resolder all the susepected solder terminals [especially take care to blue output section], by applying a little more solder. Check the base connection solder terminals of the blue output transistor. It might be loose, or transistor is defective.

Television picture colour

This is because you have something emitting an electric magnetic pulse close to the TV. Like a large unshielded speaker or large Battery. First thing you need to do is move anything near the TV away and see if that correct the issue. Next would be to degauss the TV. Unfortunately the TV probably does not have a built in degausser.

A degausser is an electro magnet in a circle. you plug it in and run it around the surface of the TV.

Picture fuzzy

I would suggest to unplug the tv from the wall for about 15 minutes and then plug it back in,and turn it on,this should reset the microprocessor and realign the colors back to normal.let Us know how it goes and if you need more help.
