Question about Acer AL2017 20" LCD Monitor

1 Answer

Acer AL2017 Monitor

I see from a previous post that you found some bad Caps on the Inverter/ Backlight driver of this monitor. I assume that they are at the output of hte Backlight. Can you tell me what value can be used as replacements?

    I replaced the 1000uf and 220uf capacitors and now the screen comes on, but the backlighting quickly dims and disappears. Then there's a hissing noise as the backlight turns off, followed by a repeated attempt. After the second attempt, the monitor turns itself off.

    Any ideas what this might be?

You will need 3 or 4 ( forget now) 220 uf 25 volt and two 1000 uf 25 volt .... just finished putting this one back together and it's great.

You need to look for bad caps with bulging/leaking tops, blown fuses, shorted MOSFET, etc.

Please read my guide to understand more:

My monitor will be black when I start up my dator. I have to turn my monitor on and off several times before I can get it to work properly.


Look for bad caps as shown in my albums here:
http://s807.photobucket.com/albums/yy352/budm/ACER/ACER%20AL2017%20BMD/

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/
Post back what you see inside so we can guide you further and it will help out other people in the future also.

NO LIGHT ON SRCEEN


This model AL2017 20" Acer monitor is known for having a bad power inverter board. The capacitors go bad, which causes the backlight to completely stop working or flicker intermittently. If you feel like you are electronically and mechanically inclined the board is easily replaced. Search ebay for AL2017 Power Board -- its about 15 bucks plus shipping.

check for any swollen caps on the power supply/inverter board and the LCD driver board.
