Re: Acer AL1916W A LCD Monitor
I have found sometime a bad capacitor can keep a monitor from turning on at all.
You get no light at all from the power switch?
What brand of capacitors does it have?
I know it's the same board as that westinghouse but can you also take pictures of yours?^Learning to walk on rice paper without leaving a trace, -

Re: Acer AL1916W A LCD Monitor
Measurement of voltages as shown in the photo are fine.
with respect to the LEDs, turn on very little,
only when you remove the power cord 5 seconds pass and shine more and turn off.Attached FilesComment

What brand of capacitors does it have?
What is the uf and voltage of each.
I'm not pro but I will try to get enough information from you about your LCD so the pro's will have what they need to work with. Jacob^Learning to walk on rice paper without leaving a trace,Comment

Re: Acer AL1916W A LCD Monitor
I would wait for conformation before proceeding. But,,, If I owned that monitor I would replace all 220uf, 470uf, and 1000uf Capacitors on the power board. 8 out of 10 monitors I see with those symptoms are repaired with cap replacement.
What year was it manufactured?^Learning to walk on rice paper without leaving a trace,Comment

Re: Acer AL1916W A LCD Monitor
That would be my recommendation also. The 'unplugged for 5 seconds definitely represents a power supply problem. While bulging is a definite sign a cap is bad, most manufacturers now know how to build them well enough to fail without any obvious signs.Originally posted by Nama

Normally, I never post repairs this quick after I do them, because… I am usually very slow.
But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. 
I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...

I ask this question in general as there are many Acer Aspire models with UEFI Insyde BIOS that do not boot to the BIOS on an external monitor (VGA, HDMI, etc) showing only the Internal LCD (LVDS, eDP etc).
It's a pain to work on Acer notebooks with a broken screen and not being able to access the BIOS using an external monitor.
If anyone knows how to force the external monitor as primary for Notebooks of those models11-02-2024, 09:18 AM -
