Question about Acer AL1916W 19" LCD Monitor
My monitor has been working fine and i shut my computer down and when it rebooted the power light would come on but the screen is black. I changed both cords out and it still isnt working. If you tilt the screen and put a glare on it then you can see a picture in the background. I took it apart looking for a bulb or fuse and was scared to go to deep. Is there a bulb or fuse that could have went bad? And if so, how do i get to it. lol
The backlight in your monitor isn't coming on, so all you have is that faint image you see.
This trouble is frequently because of capacitors in the monitor which fail. Often these parts (cylinder shaped, usually a couple of inches tall and an inch or so in diameter) have visible problems such as tops that have bulged or split, or brown leakage at the bottom on the circuit board. If you're adventurous, you can take the back off the monitor and check.
If you find any capacitors that look questionable, you can get replacements at Radio Shack or from online parts sellers. Capacitors have markings on them for their value in microfarads (abbreviated as mF or uF), a voltage rating, and a polarity. Some caps have the positive terminal marked and some the negative. Just note which goes where on the circuit board. Get replacements that have the same capacitance value, but a slightly higher voltage rating. They will be a little larger physically but should still fit, and under-rating is what usually causes the failure in the first place. Observe the polarity when installing the new parts.
This all sounds a little scary perhaps, but it's really not a difficult repair. If you're not comfortable with the idea of trying it yourself and you don't know any technically-inclined types who are willing, a TV or stereo service shop could do it. But with labor and their markup on parts, you might spend over half the cost of a new monitor.
