Question about Acer AL1511 15" LCD Monitor

2 Answers

My acer al1511 monitor started shutting down after 2 or 3 minutes, the green power led turns orange(like no signal). if i turn the monitor power button off and back on the monitor works for 30 sec to 1 minute and repeats the shut off. I took this monitor apart and found 2 470uf 25v caps blown on the power supply, i replaced the caps but this did not fix the problem.

Here are the service manual (not usre which model you have, downloads are limit to two per day):
http://elektrotanya.com/?q=showresult&megnev=acer&megnev2=al1511&kategoria=&kat2=all
You need to do some voltage checking make sure you do have 5 and 12v. The caps the secondary DC side should all be replaced at the same time, it may look OK but they can have high ESR, and they also should be low ESR type such as FM or FC series by PANASONIC. You can send me pictures if you want more help, budmrtn@aol.com

your problem sounds like you have bad capacitors on your monitors power board. once you start it, they do not have enough capacitance to give to start the monitor, but after letting it for some 10ish minutes or so, they capacitate enough to start. even then, after some time, they will lose the capacitance because they are feeding the monitor in constant power when the power from the outlet drops a bit, but being bad - they will shut off your monitor. some repair shops can change capacitors only, others would make you change the all power board

Viewsonic VP2030b takes 5-10 minutes to start


Open the monitor, examine the circuit boards. Look for small components that look like small cans, these are capacitors. If you see any that look bulged on top, then your problem can probably be solved by replacing these. Check out the following sites;

Sir Help me with my Compaq monitor MV520 it won't turn the power led flashing orange to green continously


it could be th epower supply and it could be the monitor.
power ON button should not flash orange regardless what you do. it should stay green. then orange. not orange to green to orange.
try the monitor on another PC if you can fine one.
the other thing is are the 2 monitor similar (CRT to CRT and LCD to LCD), you can't mix the the two, they will work but need different video driver to function correctly.

Hard drive is most likely dragging the 5V circuit down. Download a free Mepis CD and pull the drive to see if it will boot and run on the fly..

Hi, The part where you see some color bars and blinking green led is what we call MONITOR SELF TEST. A diagnostic pattern consisting of four colors (red, green, blue and white) appears, and the LED flashes slowly. this happens when signal cable from the monitor is disconnected from the tower and leaving the power chord for the monitor plugged in. If the monitor works properly on a different computer. then its a problem with the computer's video card sending out signal. im 85% sure that its a problem with your video card.

Are the settings on the video output correct? Is there a green or orange light illuminated. There is a difference between the Power LED and the Signal LED which is green. If you have no signal the LED will remain orange or yellow but not green. If the LED is green, then a signal is getting from the PC but not necessarily good. Check the signal with another monitor or TV if you can. Check the cable.
