You can try pulling the AC plug overnight in case the problem is caused by an IC that has locked up but it is more likely due to a main power supply that is not starting up.
This is a fairly common failure mode and often caused by a 20 cent component that should have cost 50 cents. There are points in modern supplies (called 'switched mode') that are critical to operation and the quality of electrolytic capacitors is poor causing them to decay chemically until they can no longer do their job.
You might contact the LG authorized service company in your area and ask if they have a repair or exchange program.

How do i fix a proscan tv to turn, only a red and blue light are on


Well without actually opening it up and determining where the problem is, it's unlikely you will get it to come back on. I suspect something wrong with the power supply but it could be something else also.

Monitor will come on for 1 second and then go blank and the power light go from blue to red then if you cut power back on it will come back on for a second and then shut off


moniotr switches into power save mode when it is connected to the computer and there is no signal for the computer. Try following the steps below which i recomended for another poster as well

Unplug the monitor from the power
Unplug the monitor from the computer
Plug the monitor back in.
Try turning it on.

DOES IT SAY "NO SOUCRE DETECTED" or soemthing like that???

if it DOESN'T it means there is something wrong with the computer.

if it DOES:

plug it back on to the computer, turn the computer power off.
Press and hold the power button on the computer for about 15 seconds.
Plug the computer back on.
Try turning the computer on.
if it's not turning on again there a problem either with your monitor cable, or the plug, or the video card plug. It is unlikely that your video card is broken if you hear no wired series of short and long beeps when you try turning the computer on.
Good luck.

Make sure the headpiece is charged. Turn the headpiece off by pressing the little black button on top of the earpiece and holding for about 5 seconds. Turn the earpiece back on again the same way. You should have a slow flashing blue light on the mic boom. The base station will now try to find the earpiece and within about 20 seconds the red light on the base should be steady and blue light on top should be on.
If this doesn't work you may need to manually pair the earpiece to the base by pressing and holding the Listen Volume Adjust + Button and headset Call Control Button on the earpiece until the light on the mic boom flashes red and blue repeatedly. As above, the base station will now try to find the earpiece and within about 20 seconds the red light on the base should be steady and blue light on top should be on.
