There are many circuit areas inside a TV set that can have burning components. Since you describe a colour change, I would think the fault may be in the video processor, screen biasing, or video drive path.

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


Hello
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.

Burning and fan type sound


That is probably the power section about to fail. The burning smell is going to be from overheating components. You will have to take it into either an akai repair depot or a local tv repair and have it looked at. Get an estimate first. The repair cost on this could be cheap if itis obvious and the repair gys are on the ball or it can be pricey if they just replace major parts (typical). Also have a good idea of what replacement cost is so you know if it is worth fixing.

There is a burnt capacitor somewhere in the unit. Look for any burnt or swelled up capacitors. You can also usually locate a bad cap if there is burn marks on the system board. Also test power supply with voltmmeter to make sure it is a constant volt reading.
