Re: akai pt5499hd just shut down

If you are electrically inclined, there is a power deflector board that may need to be replaced. This deals with the high voltage part of the TV, so I am not responsible. The part number we had to but and replace was BP94-01289A or about $130.

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.

Heard a pop, tv went off, then doesnt come back on

Your unit has some sort of PSU fault, or a problem that is shutting down the Power Supply Unit, PSU. This happens so that no further damage, and possible fire will occur. The sound is it starting up, shutting down, over and over.

You need to take the unit to a reputable service centre/man and ask for a firm "Quote" for the work to be done.

Akai PT5499hd that has suddenly lost color alignment

The most likely cause is shorted convergence chips and possibly a few pico fuses.

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,Pioneer2_bing.gif Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links below.

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

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*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

Akai PT50DL24 50 in DLP Rear Projection TV-NO PIC OR SOUND

check for popped or raised tops on caps in power supply. also try unplugging set for 5 minutes and resetting it. How about does your color wheel spin up? if your color wheel don't startup then your tv will also shut down. also check all fans they all should be running at turn on. if all fails i would say its your light engine.

Akai PT5598HDX/SMS won't turn on

Just a thaught, I could be wrong, maybe a problem with the power button on the remote ? It might shut the TV off, and when you do keep pressing the remote button, the red light on the TV will keep flashing like that also. Ive seen this prob on a few other blogs, so seems to be pretty common. I know I like to keep the remote pointed at the TV all the time, maybe try pointing it away for a while, just to see.
