Check on the processor installed inside the computer's motherboard, it might be loosen and make sure it is properly locked. Also check for the fan. Make sure the cpu is properly ventilated to avoid overheating that might cause the shutdown.

If its a flat screen monitor ?

eMachines flat-screen monitors offer high quality at low cost. eMachines flat-screen monitors are compatible with most brands of PCs. Issues with eMachines flat-screen monitors can arise from faulty power sources, cable problems and incompatible settings. These issues can be resolved by testing step-by-step each possible cause.

Plug the computer's power cable firmly into a working AC outlet. Press the computer's power button.

Check the LEDs on the front of the computer case to confirm that the computer receives power. Plug the eMachines monitor's power cable into a working AC outlet. Press the monitor's power button. Check the LEDs on the front bezel or power button of the eMachines monitor to confirm that the monitor receives power. Orange or blinking LEDs indicate low power or no signal. Green LEDs denote a working connection.. Perform a monitor self-test. Switch off the monitor. Unplug the video cable from the monitor. Press the eMachines monitor's power button. An eMachines logo, Windows logo or "no signal" message indicates that the monitor is working properly. Plug the eMachines monitor's video cable into the video port on the computer. Attach the monitor's included DVI-to-VGA adapter to the monitor's VGA cable if your computer has a DVI port (15 or 25 pin-slots with 1 side slot) in place of a VGA port (15 pin-slots, no side slot). Press the eMachines monitor's input button to change the monitor's setting to match the computer port used. Set your monitor to DVI if connected to your computer's DVI port. Set your monitor to VGA if connected to your computer's VGA port. Connect the eMachines monitor to a known working computer with a known working video cable if the problem persists. Contact Gateway, eMachines manufacturer, if the monitor issue is not resolved. Hope this helps.

Open the dryer door and slowly rotate the dryer drum in a counterclockwise (CCW) direction. Rotate the drum 2-3 revolutions and then shut the door and see if it will start. If it continues to just hum and not start could indicate a voltage issue, motor issue or a friction issue. Open the door again and locate the door switch plunger in the upper or lower corner on the hinge side of the drum opening. Hold the plunger in while someone begins rotating the drum counterclockwise. While turning the drum counter clockwise and holding the door switch plunger inwards press the start button. If it starts, there is likely a friction problem or motor problem.

PC SHUT down


three things i find to cause this,

one, the power supply is bad,
two, the power connector is lose or not push in
three, the heat sink on the processor has come off. This will cause the cpu to over heat and self shut off.

to test the power supply, pull the connector off the mother board and short the green wire to any black wire with a paper clip, this will switch on the power and see if it stays on.

if you need to replace it, you cannot use a regular atx power supply. E machines have a different pin out.

T6420 E-Machine won't/Reboot W/O F8 Key


No sync means no video signal to the monitor. The rest sounds like a corrupted OS. This could be from a number of reasons, including a virus. If you have NORTON or MacAfee, Your open to a lot of attacks. Get AVG free, and use Mozilla instead of IE.
The reason the fans come on full speed is the MB senses a high temp on the CPU, until the bios fan control takes over after POST. This is normal on most systems.

Tv turns off after 15 minutes of use


For bobby11 and luis, it is the power supply. Part Number EAY34797001 in the 42" and EAY34796801 in the 32". This is a known problem, and somebody should start a Class Action against LG over this one. Part is available online and easy to swap out for anyone with the most basic knowledge.
