Got an akai pt4299 and it wont power on. red light goes on in front and stays on and thats it no sound or picture. anybody help?

Whn you try to power it up does it attempt to power on before going red or does it just stay red? If it just stays red then its definitely a case of faulty power supply board. The easies way to resolve this problem would be to replace the power supply board, which can be obtained for about 50-75$ from shopjimmy.com. So let me know if you wish to fix it yourself

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

Please post back what you find.

Hello,


Is it a CRT or a DLP/LCD projector? If not a CRT, a worn-out projection lamp can cause this symptom. When it is a DLP projector, a faulty Colour Wheel sensor can be the additional problem. If it is a CRT projection unit the High Voltage and deflection circuit must be examined...

Please tell me more about your unit...

Check the picture tube it likely needs to be replaced.

Mine is the 5volt regutator. It works fine untill I put a load on it then it craps out. Need to know what the 5v regulator part # is.

The power supply board needs to be replaced or repair. No other quick fix is available. Thanks

won't turn on, green light comes on and them click sound and goes red, never a picture. continues to cycle through this every ten seconds or so

ordering a power supply from either vancebaldwin.com or partstore.com

Nothing worked, so I bought a new camera.

Thanks...Carole

I have the same problem. My Akai 27" flat screen shuts off inconsistantly. Sometimes it will stay on for hours and then we have to turn in on every 2 minutes. It seems to be getting worse. Is there anyone who has found a way to fix this?
