Question about Acer AL1913W 19" LCD Monitor

1 Answer

Monitor won't turn on normally. Possible Inverter problem?

I have had an Acer AL1913W for a few years and when I first got it, I had to send it to get the inverter fixed. It's worked fine since then.

A few days ago I cleaned the monitor through the vents with a really powerful jet of air (don't know it's the cause or a coincidence) and now if I leave the monitor off for a few hours, it won't go back on. It sort of stutters to go on and then goes black but I can still see the image with a flash light. If I turn it off and on a few times, it will eventually light up and will stay working. It seems it needs to warm up first. If I leave it on (with the black screen) for a minute or two and then turn it off and back on, it turns on immediately.

Could I have knocked something loose inside with the air? Any ideas what to check inside to see if something needs to be replaced or fixed?

    Is there any way to check and see if they are still good?

    It wasn't a can of compressed air, I used a vacuum cleaner on reverse and it gave a pretty strong blast. I think it messed up my dvd-drive as well.


    Would it be overheating if it doesn't go on after being off for a few hours?

Not likely that you knocked anything loose.
Keeping it clean is a good thing and helps stop overheating of parts.
Power should be unplugged when doing this. There is a slim chance if using canned air that at times liquid (usually freon) will come out and could cause a temporary short.
Ironic thing is: Overheating is what yours seems to be doing.
The capacitors on the powerboard or inverter are more than likely starting to fail from heat and age and should be replaced before it gets worse and eventually burns out a part that is harder to get and harder to diagnose.

I have v193w acer desktop lcd screen suddenly it went black the blue light (( which mean that it's on and every thing works fine )) is on all the time but nothing appeared like the the screen is completly...


Ive had that problem recent, same monitor. Same months to be exact, though started around October 2010 then got worse. Do not send it back to Acer, I did and the cost was 20 bucks to ship to them and all I got was a note and monitor back saying they tested and then did Extended testing and found nothing. Not even had it for 1 year or 2 years to say, 3 year warranty. Just going to buy a new one and perhaps a LED from ASUS, the V stands for Value on Acer website, guess I got what I payed for. Think it was $166 I payed for this thing. It is shame, as its nice monitor but I cannot have it not trusty like this, cannot even play some games without it going off like this. Worst if I put the monitor in Graphics or Movie mode makes it worse it seems.

When I turn on the monitor the green power light comes on and stays on, but the screen flashes on and of as it tries to light up and a clicking noise can also be heard. This happens every second or so...


Look for bad caps.
If you are going to DIY and have proper tools and know safety precaution then please read on:
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 ACER monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

You may have dying power supply problem due to bad caps, that will be the first place to check.

Acer monitor won't stay on


That looks like an inverter problem. If the monitor is still under warranty, contact the manufacturer (3 years for both parts and labor if purchased new). Otherwise, open up the back of the monitor and remove the shielding. Look for scorch marks, soot or leaking or bulging capacitors (look like cylinders on tripods). You could just replace the capacitors and the resistor that acted as a fuse. However, for $50-150, depending on the inverter, you can replace the entire part (unplug the wires for the backlight(s) and other connections and swap them).
You can also check the inverter by looking for the high frequency EM put out by the unit. Some high end multimeters will measure this (as will an oscilliscope). Hold the multimeter probes a fraction of an inch apart about an inch above the board (with the multimeter set to read frequency). If the inverter is good (and the frequency is reasonably close to the multimeter's range) you will see either a 1 or a value (kHz). If the inverter is bad or too far out of range, you will see a result near zero.

Once you have the monitor open, record the part number on the board with the damage, including the REV number if any. Search that part online (lcdparts.net and other sites have parts for monitors). Get the correct unit if possible. Some sites sell universal inverters and those can be used. However, you may find the controls reversed (up to lower brightness).

I hope this helps.

Acer X223W monito won;t wake up after sleep.


I have a dual monitor system, both are the x223w. Same problem but only on the second monitor. Backlight shuts off.On/off light stays blue. I have to turn off the monitor and turn it back on. I returned it and Acer could not find any problem so I got it back. No problem for awhile and now a few times over the past couple days. Not good...

Acer AL1717 moniter hissing and goes black


Include me in the people burnt (no pun intended) by crappy quality Acer monitors. Will never buy their stuff again. Ironically, this infrequently used external monitor burnt out overnight, just a few hours after I had actually checked out and decided to buy an Acer Windows 8 15.6" i5 laptop. Definitely not buying Acer again.

We have repaired a couple of these. R1 on board normally burnt also C6 and C22 bad on inverter board. Replace these and it will probably work. R1 is 10 ohm. Capacitors are 220uf 25v.

My monitor turns itself off


If it's only a few months old then send it back under warranty.
The fault you have is the inverter circuit.

Hope that helps. =)
