The screen after sometimes will off by itself. Power off and power on, the screen will come back. It will power off again and i need to do a few times before the wcreen will be back to normal. what could be the cause? I think it is the video unit that may have problem, but which component can cause it?
The screen after 1-3 seconds will off by itself. Power off and power on or any signal from computer and the screen will come back for 1-3 seconds.
So it is not overheating.
Could you help ?
Thanks a lot.

I have a very similar problem with my AL1916, except that it now happens almost right after a cold startup...so overheating from long periods of use is not a factor anymore. It could be a my video card, but I use a second LCD, Acer AL1914 and nothing has happened to it all ever. So perhaps an imbalance of the models? i don't know, I used them both together with no problems for a year and a half. So any comments would be appreciated.

My Acer flatscreen AL1914 powers on and off by itself whether the computer itself is on or off. I changed the power cord thinking that might be the problem did not help. Any other suggestions? Have had to resort to unpluging at night so it doesn't turn on because the light will then wake me up. Any suggestions out there?

I am assuming this is on a desktop and not a laptop. Might be an overheat issue. If it runs for a certain amount of time then shuts off, that is a tell-tale sign of overheating of some critical component inside. So, either something is making it overheat, or the component is weak enough that it is unstable in the environment it is in.

sometimes if there is a fax board on the back and the power switch is off on that it wont light up the display. either that or something is wrong with the display itself. sometimes those ribbon cables have to be replaced that power it.
HI,
Do a power drain, this may cause by an electrical charge in the motherboard itself,Im Not really sure how it affects the display of the computer but this method usually fix such problem like that, First, removed the battery then unplugged the AC adapter the press and hold the power button or the ON/OFF button for at least 30 seconds then connect the power supply back to your computer then turn it back on, if nothing happens, there is a possibility that the problem is with the LCD or monitor itself, maybe it will need a replacement...
Hope this will help...Your response is very much appreciated...
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?
This is characteristic of a poor contact someplace within the unit NEAR the connections for the display. It may also be a bad plated-thru-hole in the circuit board. This problem could also be on the display circuit board itself. They often have a complete microprocessor right on the display itself.
The vibration from the keys causes the connection to break, and the re-cycling of the power sends enough of a pulse to break down the oxide at the poor connection.
These can sometimes be found with freeze spray circuit cooler and often by applying gentle pressure at suspect points on the boards and looking for changes.
It for certain is a get out and get under repair involving taking out a lot of case screws and VERY careful handling of the cables within the unit.
The screen after 1-3 seconds will off by itself. Power off and power on or any signal from computer and the screen will come back for 1-3 seconds.
So it is not overheating.
