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?

    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 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.

Urgent problem with my relisys monitor, please help!

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.

Consult your technician there is a semiconductor problem inside your tv. Probably lose connection, and need to resolder.

But that is the only way -its replacement time Nothing for you to fix
