Won't stay turned on.

Look for a thermistor near the lamp and ballast

Shut it down by holding the power button until the screen goes black, don't tap the power off button, wait for the black screen. Then let your phone charge for a few hours (maybe over night) with power off and see if that helps.

When the CPU in the computer or laptopoverheats then it will shut down (i.e. thermal overload) and won't boot upagain until it has cooled down. If this is the problem is not fixed then theCPU will eventually fail.
A faulty fan causes this problem or the fan and heat sink assembly are cloggedwith dust.
Check the CPU fan to see if it spins freely, if not replace the fan. If the fan and heat sink is clogged withdust the remove the dust and make sure the vents are clear and dust free. Use acan of compressed air to do this.

Hold the power button in for a few seconds it will shut down. Then unplug system and push the power button down with it unplugged then replug it in and power up again. Then do a proper shut down again to see if the problem fixed. I hope this assisted you. John

Ok, another words, monitor powers up for few seconds and shuts down by itself. If green LED on the front panel turns off as well or stays on?
If stays on, then inverter turns into protection mode because of old backlight lamps.
If it turns off in same time with an image on the screen, then there are some bad electrolytic capacitors in the power supply.

disconnect all of the speaker wires at the amp and turn your system on -if the amp stays on then you likely have a roasted coil in one of your speakers somewhere and causing a short which is shutting your amp down into protection mode-if the amp wont stay on with nothing connected to it then you have probably roasted something inside the amp and uhhh good luck bro

You may need new inverters, CCFL's, or your power supply is not [providing regulated 24 volts...

Inverters

We have these Akai boards in stock if you need them.....

Hello, The blinking pattern you're observing is a result of a heavy current load on the power supply. The power supply could be defective but more than likely the scan or sustain boards have a direct short on them causing the power supply to shut down and display the error. A technician will be able to determine where the load is coming from and replace the appropriate board or component. I hope this helps you. Joe Weibel CustomElectronics.Org
