Question about Acer AL2017 20" LCD Monitor
It may not be related to room temp, but it sure sounds like there is an internal problem relating to temp. Meaning, there is a component (probably a capacitor) getting over heated or leaking. If this is still covered under the mfg warranty, I would contact them to get it fixed. If not, then taking it to a repair facility that can repair it is probably a good idea.

The floating 'Dell Self-test Feature Check' dialog box should appear on-screen on a black background if the monitor cannot sense a video signal and is working correctly. While in self-test mode, the power LED remains green. Also, depending upon the selected input, one of the dialogs shown below will continuously scroll through the screen.
If your monitor screen remains blank after you use the previous procedure, check your video controller and computer system; your monitor is functioning properly.
- This box also appears during normal system operation if the video cable becomes disconnected or damaged.
- Turn off your monitor and reconnect the video cable, then turn on both your computer and the monitor.
