Question about Acer Professional P211 21" CRT Monitor
I have a pretty new(1 1/2 months) old Acer computer with the lcd monitor. The computer itself comes on, but the monitor displays nothing. I have checked the signal cable at both ends, and they seem fine. The monitor says "no signal" everytime I unplug it, or turn it on and off. It also says no signal when I unplug and replug the signal cable into the computer itself. Any ideas?
Try the monitor with another known working computer, If ng there also, then have unit repaired under Acer warranty.

Hello mat78, Unfortunatelly the problem is hardware based. You will need to have the monitor repaired in a service center. Here's why: LCD/TFT monitors don't produce light themselves. They are composed by a matrix of transistors (TFT - thin film transistor) that have the property to reflect or allow some light (certain wavelenghts)to pass through them. They don't produce light by themselves. Instead there is a fluorescent tube (neon like) light inside the monitor and that's the light source used in order for you to see what's on the screen. A flourescent light is suposed to last pretty much, i don't think yours has a problem, you say it works for some seconds or so. Instead your problem is most probable with the inverter circuitry that powers on that light. It's a common problem among these types of monitors but in your situation i don't think it will be an expensive repair. In the case that the screen is dark (in a dark place you can't read or view anything on it) but if you apply light to it ( a flashlight or something) and you see something, then the problem is most likely to have occured with the invertor. Try to ask at a local service center for a repair, this shouldn't be an expensive procedure. Hope this helps.

SOURCE: monitor goes black
Sorry to have to tell you this, but this is common in LCD monitors. The reason that it is going black when it boots is for one of two reasons. You either have a bad power supply that powers your LCD or your LCD's backlight is blown. These can be repaired or you can purchase a new one. But if it goes black 9 times out of 10 is because the backlight is bad. These can be repaired!

Probably the settings on the computer graphics card output.
You need to selct the external screen.
Just to be sure it's not a screen fault, are you able to test it on another PC (desktop, not laptop)?

The LCD panel is going bad. Nothing is wrong with your computer. If the screen is not under warranty, then I would suggest replacing it with a new one

Does it work well with other computers?
If you are connecting to a laptop, try switching display modes (like you would do for a projector)
