Akai rear projection tv suddenly stopped working.


This set with Akai is actually made by Samsung (they own and use the Akai name).

If lamp light etc and you have heard a cracking sound it may be the color wheel.

You can remove the lamp and look where it faces--look and the wheel can be seen----is it shattered or missing plastic pieces?

The wheel commonly fails in this fashion and is turning at over 12,000 rpm. The set will detect if the wheel is stopped or moving too slow and just what you describe will happen.

Wheel is widely available and You Tube has video instructions for replacing them by model number.

Questions?

You have a good eye, that would be the color wheel. You can call samsung at 1-800-samsung to find a repair center, it is not an easy job to replace it yourself.

If you had a picture, even briefly, after the sound you heard then in all liklihood it's the color wheel that broke. Not a DIY friendly project unless you're very good with electrical/mechanical repairs, especially small fragile items :(

The buzzing sound is usually the color wheel gone out. Remove the bulb and housing and look behind it, you can see the color wheel, it may have shattered and there will be glass on the bottom of the tv, or it just may not spin. You can repair it yourself, just put make model and replace color wheel into google and instructions will come up.

This is undoubtedly a broke color wheel. The wheel is made up of four small slices of colored glass, Cyan, Magenta, Yellow and Clear. Each slice is fixed into a groove on a brass hub. The high-pitched "whirring" noise that you hear on start up is the wheel spooling up at high speed. If one of the "slices" comes loose from the hub it can break, bind or start scraping. Regardless, there is a sensor that reads the speed of the wheel and won't allow the unit to come fully on if the wheel doesn't come up to speed (which it no longer can). Bottom line...Game Over. It's simply too expensive to fix. I personally am hoping for a class action suit on this obvious piece of junk retailed by Dell. But think of all the extra money they are making from people rushing out and spending up to $300 for a bulb that won't solve the problem. Ahhh...gotta love free enterprise!

Dark band at top of screen...now whole screen


Pop sound is probably the Lamp or maybe the color wheel. When you unplug and try it on do you hear a whirling or winning sound ? Is it followed by a slight ticking sound ? If you get the whirling and a ticking sound it's probably a bad lamp. If you don't hear the whirling sound you may have a bad color wheel. The parts are both made of glass. The pop you heard was one of them breaking. If you can't tell, order a lamp you will need to change it eventually anyway.

Remove the lamp and look into the left side of that compartment to see if you can find glass/color wheel bits and pieces. I just recently had this happen and when I turn on the tv the red power on indicator blinks twice. Check to see if you have power to the tv
