    This also happens to me. I turn on the TV and you can hear the sound of it turning on, then nothing happens except the timer light blinking.

Sounds like your convergance ic's shorted on you.
you can replace the fuse in the power supply and disconnect the conv board and see if it comes on. if so order new ic's and check all resisters for the correct values.
good luck

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?

54 inch Akai Tv makes brief siren noise when plugged up.


I have had a few of these with similar symptoms. In one case the set had a coolant leak onto the circuit board. The way I found the problem was to unplug the power and removed the front cover.(most models you can remove speaker grill and access panel) Make sure power is unplugged. When I looked in using as much lighting as possible I was able to see small puddles of coolant that had dripped onto the circuit boards from the picture tubes above. The other one as I recall had an arcing picture tube which caused a screeching type sound seconds after plugging in, then it would go into protect mode and just have a blinking light. I'm sorry to say but in both cases it was deemed unrepairable due to expense or lack of parts. Although, in many other cases I was able to clean the leaks and circuitry to restore power. Keep in mind this is just an educated guess. Good Luck, Russmann.

The STKs are common and if you have an experienced electronics tech around they can replace them for much less money but the tech must have advanced soldering and IC exchange experience.

The STK ics, two of them, can be purchased on line for around $20 to $40 each.

http://www.partstore.com/GetModel.aspx?MfgName=Toshiba&BrandName=Toshiba&ModelNu...

Partstore has two models available - one for around $40 and another for around $55.

The part number is STK392-110 and if you google you can find them for as little as $6/each but I don't recommend the cheap ones as they are not reliable.

It takes a good tech around 3 or 3 hours to take the old ones out and solder in the new ones. Also, it is likely one or two resistors are burnt and will need replacing as well.

Picture went off still had sound then i turned off at panel now only red timer/standy stays lit sony 61" projection


First plug in again and look at led light, the amount it blinks tells what is wrong. Then if it stays lite it tells something also. You can try Display-channel 5-volume +- Power(service mode). Then Channel 8-enter(test reset). If this doesn't work then you will have to replace somethings like F601, R607, Q601, IC601, R612, VDR601.
