Question about Acer AL1912 19" LCD Monitor
Hi, my monitor goes black a few seconds after powering up. I can turn it off and start again with the same result over and over again each time I restart. I have opend the back of the monitor and checked the connectors
but can find anything wrong. Please help me.
Kind Regards, Ulf
The problem with this monitor is a leaking capacitor on the power supply board. It is the middle one at the top in a row of three. The value is 10V 1000uf. Common problem for these.
Remove 4 screws from back of display. The case can be popped apart with a small flat putty knife at different points along the two seams. Three latches on each side and two at top and bottom. Push and twist at the latch points. There is a metal cover over the two boards. Power supply board to left. Screws and plugs can be romved. Unsolder Capacitor and replace. Radio Shack probably has them. Maybe a couple bucks. Be sure the power has been off for a while. These also have problems with the button board and corrosion at ribbon cable.

I was asked by a friend of mine to look at his monitor AL 1912. Basically, inside is the power supply board that you can replace and you can get them online. That is the easiest way to fix the problem instead of looking for a component for your board. Mine, I believe, the problem is the rectifier ER1002FCT being shorted. I tried looking and found a site but they only sell in bulk, mainly dealing only with business owners.
I saw the board one time at ebay for $25.00 plus shipping of course and the seller is from Australia. Personally, I'd rather stick with the US sellers because I had a bad experience waiting for my item to arrive before because of US Custom. I know they are only doing their part.

I had a similar problem I had two of these monitors UK spec completely dead and on dissasembly there were two capacitors on the power board which had clearly blown - their 'roofs' were bulging. These were 1000uF 16v radial electroltics - a similar repair to the above cost £5 (say $10) inc P&P to get replacements for both monitors and both work fine now.

Had the same problem, monitor went dead so I took it apart and the two capacitors had raised roofs. Got 6 new ones from Ebay for £2.10 all in and replaced two. Works brill, if they go again I would replace with 25V though. Thanks jungleg49
