Having problems with your Acer AL1916W 19" LCD Monitor ?

Green light comes on for a few seconds then turns orange

\015 I got this monitor free, a Westinghouse L2046NV, plugged it in to see if it worked and the only thing was a black screen. I noticed that the green light came on and then went off and the orange light came on, but nothing on the screen. Went on the internet to see what was the deal and found a repair for it. Removed backing, etc., and accessed the power board. On first inspection found 220uf 25v cap popped, but none of the others. They are all perfect. Mosfets 40T03GP's look perfect, board perfect front and back. Under a high intensity light and a 10 power magnifying glass I can see the copper bar inside the pico fuse's, S, for the part of the board that goes to the mosfet's. It appears these fuses are not blown as I would think there would be black and they would appear "blown", but I don't think they are. I replaced the popped cap, put everything back together again, plugged it in and pushed the power button. The green light came on for a few seconds and then it went off and the orange light came on, same as when I first checked it out before doing anything. Took it apart again and removed the power board to make a very detail inspection of the solder of the cap. I have years of experience soldering but not so much on IC boards. But have done several boards, both computer and power with success, feel confident about what I'm doing, but since there could be more to fix, now I'm having some doubts. I'm going to ignore my feelings and move on to the next fix, but I need to know from you if there is anything wrong with this board to begin with. When you turn your computer on first thing you push on the button on the monitor and it turns green and things come on it. This monitor isn't connected to anything, but just plugged into the wall plug for power. Then when you turn your computer off, just as it goes off the monitor light turns from green to orange. Then you push the button and it goes off and you know the monitor is off as well as the computer. This seems to be like that, that the monitor is just in the "standby" position. I've read just a few sites on the internet about the same problem I have but they all go back to the same problem as the other people's problem about the monitor having a power problem. So, that's where I'm at right now with one cap replaced and having the same condition as I had when I first checked it out to see if there was anything wrong with it when I first got it. Do I have a real problem or do I need to go on and replace the other caps, mosfets, and then it will be fixed. I believe this is a good monitor and I'm looking foward to using it. I'm waiting to hear from you. Thanks.\015

Answers :

Hello,

If you have a popped cap then the mosfets are blown. They blow as soon as the cap shorts and pops. You need to replace both mosfets and the 220uf caps and test the fuse with a multimeter I would bet its blown too.
