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.

Burning smell and picture is distorted.


Projection sets have two very common problems.

The first common problem is convergence


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

NO DIGITAL TV SINGAL, WITH ANTENNA


You will need to connect to a satellite or cable provider that will give you a signal box and remote to pick up digital signals and your favorite tv stations. Everything is turning digital.

I just replace convergence board on my akai tv and


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.
