GWL Washer won't spin only beeps; Diagnostic lighs:the third light is lit up green in the bank of lights on the left; the first light on the right is lit up orange and the third is lit up red. Thanks,Hepi
The red light on amplifier relates to power supply while the green light is indication of sound functionality. An amplifier that allows sound to generate should display both red and green lights. Howeever, some amplifiers would display only green as long as the sound is functioning.
Solving the problem
First, a red light still on means the power connections to the amplifier is fucntional least requirng repairs.
Second, the green ligh should turn on once the stereo were tuned up to produce sound. If the stereo is still on only least produce sound on the amplifier, check on the connection wires between stereo to amplifier that may have disconnected due to woofing or dubbing sound generals with unfirm wiring.
Dear,
Just disconnect the monitor data cable from PC and see, any cable discunnection message comes in Monotor. If that comes in monitor, there is no issue with it
if its the red flashing light on the tower, its the hard drive activity light.
when the monitor goes on stand by, does the tower retain power? (green light on and flashing red light sometimes?) Does your keyboard's scroll lock/num lock/caps lock keys and keyboard lights work?
This is a case where something that is getting switched on during start-up is causing the power supply to fail... probably due to a short. How ever I believe the short is in the power supply
This is an older HP model ( I have a 530N) with teh same problem. I bought a new power supply and installed it.
I agree it isn?t the monitor but I would suspect the video card you are connecting it to or the PC itself. Generally if a monitor doesn?t detect a video signal it will go into hibernation mode, typically displaying a no signal warning and changing the LED color from green to amber.
When you start the computer is anything displaying at all? Are you sure the PC is powering up and booting?
