SOURCE: akai tv went blank

if you purchase a nine pin RS-232 connector cable with a male end and a female end you can hook your TV up to your computer. You can actually run a diagnostics program, and tests on your TV! The cable is like 5-10 dollars depending on length and is availible at most local computer stores. Just hook the cable up to the data port beside your PC input on the back of the TV. Good luck! (just saved you 100 tv repairman bill) and also check the bulb to make sure it is still good! The service guide to this TV has ALL the answers to your TV at www.nodevice.com , search in service manual and it has all the codes to reset your tv and counters for the bulb for $10..(for the manual that is you just download it to your computer then print it off)

SOURCE: PDP4247 Akai. Cablevision powered.

The tv goes into standby. 2 possible causes:
1 - the power source has aged and the voltage it delivers to the other components of the tv (in particular the control processor) is no longer stable: if the voltage drops below a certain level the processor just shuts down, putting the tv in standby. The power source will have to be checked and the aged components replaced (it's most likely the capacitors).
2 - there is a power fluctuation on the mains power line - the others don't shut down because they have a lower power necessity and they are able to coup with that.. The only way to test and fix that is to run the tv thru a UPS.

This is a sign of a lack of the luminance signal which may denote a problem with the chromanance signal ariving fast to the screen then the Luminance signal this is video problem. You will need to have a qualified TV technician look at this.

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.
