I have a 56" samsung rear projection tv that won't turn on. the red standby light is lit and when i push the power i hear two clicks and the green timer light flashes quickly then the green led stays lit...


I suspect you probably have a bad LED assembly. It could be either the red, green or blue that is bad and give you the same symptom. The problem is locating parts for it as it looks like the light engine is no longer available. I would have a technician look at the TV to verify this and what parts are needed for repair.

Tv wont turn on get audio then tv shuts off timer lite blinking


If TV stays in stand by with audio but no video, then common faults are the ballast board, or a fault on digital board.

If the led stays blinking , and tv turns off then the TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

Akai PT4298HD problemo


I'm not a repair guy, just happen to have one of these TV's. Seems to me that unplugging the Convergence Board removes it from the equation and suggests something else might be the problem. I got most of my help from here and also from this thread:

http://www.tv-forums.com/forum/TV_Equipment_C4/Projection_TV_Forum_F24/Samsung_42_Convergence_problem_P4569/

The samsung TV is the same TV as this Akai, it's just a rebadged Samsung.

One important difference in my TV from yours. I did have a timer light, and with the back off, I could hear it power up when I plugged it in and turned it on. The timer light would flash then it would go off.

When I removed the convergence board, I could clearly see burn marks on the bottom of the board where one of the amps was soldered on. That gave me some piece of mind in ordering the part. I just scanned that other thread but remember some people talking about the power supply failing as well as the main board, you might pursue those avenues.

I wish you luck in fixing this!
