Question about Computers & Internet
Something happened to the monitor. It was originally plugged into a desktop computer. It stopped working. It will turn on for about 1 second, then go black. I unplugged it from the desktop and put a different monitor in its place. I now have the Acer monitor hooked up to my laptop just to try and test it, and its doing the same thing. I can turn the monitor off for a few seconds, then turn it back on and see my screen from my laptop, and then it cuts out. im using D-SUB cord to hook it up to the laptop, because i dont have a DVI-D cord or port on my laptop. I have seen a message that said check DVI cord or something like that. Does anyone have a solution?
I unplugged my monitor and then plug it back in after moving the wires around and now it just flashes between blue and amber?

A monitor that flashes on for a second and then turns off is a sign of a bad capacitor, or multiple bad capacitors. If it is no longer under warranty you can fix it for a few dollars at the electronics store. Unplug the monitor, pull the back off. Look for the capacitors. They are the round water tower looking things. The top of the bad ones will usually be bulging, or leaking. (the top should be flat).
Grab a soldering iron, and be sure to note the polarity (there will be a dash on one side of it, like on a battery) so that you can put the new ones in the same way. Putting them in backwards will likely toast the monitor so get this right. heat up the solder joints and pull the capacitors off. Take them to an electronics store, and buy new ones. ( the capacity and voltage need to match. 12V 500uf ... something like that, match the numbers on your capacitor(s) not the numbers I wrote here!
grab your soldering iron again, and making sure to use enough solder, but not too much put in your new capacitor(s).
I hope this is helpfull to folks.

I have a 19-inch Acer AL1917W LCD monitor with that exact same problem. Mine is out of warranty. The problem is a bad capacitor on the power supply IC board inside the monitor. My problem is a stupid lock at the back of the monitor; it takes a special key to open that lock.
There are quite a few small (cheap?!) electronic devices with such a problem (the symptoms may be different on different equipments but the cause is the same bad power supply capacitors). The root cause was a bad batch of capacitors from China. The end-product manufacturers, like Acer, Pansat, Mitsubishi, Sony, etc) know about this problem but will not admit to it, nor fix the problem unless you bought an after-market extended warranty.
I have already repaired a few equipments with this problem. Anywhere from 1 to 3 capacitors may go bad at once. Radio Shack sells those capacitors (420 to 470 micro faraday); less than $4 bucks for a pair.
