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.

Picture suddenly appeared out of focus, with different colors not lined up as they should be. A horizontal line shows up as two parallel ones, one red and one blue. This all happened to the accompaniment...


This is a model first sold in 2000---if convergence is skewed and will not align in the customer menu:

It uses two of the STK-392-110 convergence chips--I suspect if you smelled something that when the chips went bad one or more of the protection resistors around them toasted--burned to protect the set from the short.


Both chips and any bad resistors need to be located and replaced--parts cost On Ebay would be less than 30 dollars--I can tell you the best seller there.

If you or someone you know can do the repair you can save the set and a lot of money--Most shops are going to charge at least 300 for this kind of repair.

It should be able to be fixed right in your home--I know as I have repaired hundreds of sets with this problem.

If you need help or advice--let me know--I am here to help.

Burning smell and distorted picture


Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV 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, Zenith, and others. You can get a convergenece repair kit from the link below.

Common Symptoms include....
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on - TV may also make a chirping noise.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a solution

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from www.TvRepairKits.com

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.

Burning smell and distorted picture


One of the components in the horizonatl deflection circuit went bad like a capacitor,the price will depend on the actual part that went bad and your location,the service call in NY could be 300.00 but in pittsburgh might only be 150.00.I still belive is wort repairing.
