Hp desktop blinking green light won't come on

mine does that when it's in stand-by mode. I just push the power button and it comes on....

Assuming you've already tried that....push and hold the power-button down for 5 seconds and the power SHOULD go out. *IF* it does not, then disconnect the power cord in the back for 1min....then reconnect and try to boot. If it *DOES*, then do the same...unplug the power cord for 1min and reconnect and boot.

Carrier outside Unit will not power on. Every 45 sec's to a 1min it will make a humming sounds like its trying to power on but wont. The fan unit inside will come on but will not disburse cold air

You probably have a bad run capacitor in your outside unit. You will need to cal a service tech to test and replace it, until then turn your system off until it is repaired. Continuing to try to run it will over heat the compressor and fan motor and cause them damage.

Turn monitor on picture stays on for about 30 sec to 1min then goes off.

If it is just the screen going dark then your backlight controller is faulty and needs repair.

My tv will turn on there is no picture and it


The only two parts that can cause scratching sound are the color wheel (if present) and the cooling fans.

The TV must be taken apart and tested by a technician.

To get in touch with a qualified technician ring the number listed on the user manual or check your Mitsubishi support website.

My acer monitor shutdown after 1min on

Look inside to see if it has any bad caps in the power supply, also look for 5v and 12v in the power supply, 90% of failed monitors are due to bad caps, see examples here:
