Re: Acer AL1916W

with the multimeter set to 200 ohm:

black on 1, red on 2 - 1
black on 1, red on 3 - 1
black on 1, red on 4 - 1
black on 2, red on 3 - 1
black on 2, red on 4 - .4
black on 3, red on 4 - 1

red on 1, black on 2 - 1
red on 1, black on 3 - 1
red on 1, black on 4 - 1
red on 2, black on 3 - 1
red on 2, black on 4 - .4
red on 3, black on 4 - 1

I will remove the rectifier tonight and retest.

Thanks

Re: Acer AL1916W

Just to clarify, I should check the rectifier with it desoldered from the circuit board?

Here is a picture of my multimeter....

Re: Acer AL1916W

Please bare with me... I am a total noob when it comes to this stuff. The multimeter I'm using has many different settings, and I found the resistance tone setting which should give me a tone when touching the leads of the 2A/250V fuse, right? I think I was using it incorrectly and misread that the fuse was fine. I get no tone at all when touching the ends of the fuse. Should I go ahead and order a replacement from digikey?

Also, could someone recommend the most appropriate fuse on Digikey's site?

Will part # F3292-ND or F3297-ND do...

Re: Acer AL1916W

The fuse is fine, how do I test the rectifier to see if it is shorted?

Hey all,

I've been lurking around this forum for the last two weeks as I have recently become interested in repairing dead monitors, and after successfully repairing an emachines monitor with bulging caps, my inexperience got the best of me with an Acer AL1916W. I got two from my corporate office, one dead and one working fine. After replacing the smaller caps on the dead monitor's power supply, I still have a dead monitor. The power LED light doesn't light up at all. I swapped PSU's with the good monitor and it works fine, so at least I've narrowed it down to the PSU. The only...
