Question about Acer AL2223W 22" LCD Monitor
Plug it in with no inputs connected,press the power button and nothing happens.no power led. how do you remove the back cover to test for power?
I suggest you don't.
There are no user friendly replaceable parts in there.
There May be an inline fuse in the AC circuit, but it's probably a circuit breaker. (Closest thing to a user friendly part, that you'll find)
I suggest you take it to a 'Mom & Pop' computer shop, and see if they will check for a blown fuse inside. The small qualified shops like these, have real computer techs, and not 'Geeks are Us'.
Plus they're cheaper.
If it isn't something simple like a blown fuse, or bad circuit breaker, it's probably the power board.
(Usually the front cover comes off, from loosening it on the backside)
The reasoning for dissuading you from opening the monitor, is that there are Electrolytic Capacitors inside.
They are designed to hold a charge for weeks, sometimes months.
Should you touch the terminals making a circuit, or touch the circuit they're in, and complete a circuit, they could release their charge to you!
This can easily result in a bad shock, or 'Put X's in your eyes'.
(The Electrocution warning on the outside is For Real!)
