Question about Acer AL1914 19" LCD Monitor
My monitor shows no display or lights at all now as if it wasn't plugged in. Previously it had another problem whereby the menu would keep appearing on the screen on its own then sometimes disappear and appear again. Pressing the buttons sometimes took the menu off and sometimes the buttons didn't appear to respond at all. The button problem had been intermittent over a long time but getting very bad just before the screen died.
First of all you will to replace those buttons as its useless after few years. as per your problem is concern you might see some change after replacement. still it does not work then there is a video problem 1 crt filament supply less 2 voltage on g2 is less . 3 check voltage on video ckt to be normal. 4 crt base loose. 5 there might be crt weak if it is old. hope this will help.

Tips for a great answer:
Shine a flashlight on the dark screen to see if you barely
see the icons on the desktop. If so, then the LCD Inverter is bad.
Plug in an external monitor and see if the display shows up on it. It can be any kind of monitor even the old big fat crt monitors as long as it has a vga cable to connect to your computer's vga port. If so that proves your video card is ok. The video will show on most systems when you reboot without you having to do anything. Some systems will require you to hit the FN (Function key) + F1 thru F12. Hold down the FN key then hit the correct key for displaying on the monitor (F1 thru F12). The correct key will normally have CRT/LCD on it or it will have the icon of a display.
If you see no icons by shinning a flash light and the external monitor works, then your screen is bad. If you see no icons by shinning the flash light and nothing shows on the external monitor, then most likely your video card is bad.
For a Desktop:
Try using another monitor on the computer. Borrow a
monitor from a neighbor, friend, relative or co-worker and connect it
to the computer. If the Borrowed monitor shows the display then your
original monitor is bad. If the Borrowed monitor does not show on the
display then you Video Card is bad.
