E machine monitor turns itself off and on

The temperature sensor should be mounted correctly in position

After a while LCD monitors develop problems that are usually caused by faults in the internal circuitry. This could be an issue with the power capacitors failing. If you feel confident enough, you can remove the back cover and check to see if any capacitors are bulging or leaking. (Give it at least 24 hours unplugged to allow the capacitors to discharge before doing so). I found THAT little bit of knowledge out the hard way

This sounds like the monitors power supply is failing. (if the monitor is truly right off) Use a flashlight to verify the back-light is not just the culprit. If you can see faint image in the monitor with the flashlight, then this would point tothe LCD inverter is failing. Its most likely the power supply board within the monitor itself. Typically It takes 3 35v 470uf capacitors to fix and a little patience to get apart. Do a bit of googling on "replacing the caps in a FPD1975W" and youll see what i mean. Cheers.

sounds like an overheating problem. you can try blowing out the back of the monitor, or putting a fan close to it. If it is really dirty it will shut itself off so as to not get damaged. is it crt, or lcd?

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.
Give us updates if you need more assistance

Please try to Turn the monitor off. Hold down the Menu button while the monitor is turned off, then press the Power button again to turn the monitor back on. This should unlock your OSD menu and remove that message from your screen. best regards

this could be many things tell me where do you think it is coming

What happend when you plug an external monitor into the VGA connector?

Hello, It may be the power is set wrong. Click start, control panel, power options. From here you can set the amount of time you want the monitor or hard drive/s to remain on until the shut down or go into hibernation. Hope this helps.

Hey Mate, being honest weve sold alot of TFT monitors and most are hard to hear with all the volumes turned up, only thing you can try are. turn volume up to max on the monitors menu, also double click on the little speaker icon on the bottom right hand corner of the screen and a volume menu appears turn up WAV, & the main one on the left. if you are not getting any sound at all check you have the audio cable from the monitor plugged into the green connection on the back of the pc. Afraid thats the only options to get it louder or buy a set of speakers to get the sound louder. All the best John
