Re: Acer S231HL LCD LED Monitor - No power



I have replaced those four caps, two each, on the DC power input/signal input board and monitor functions buttons control board and the monitor is back working fine now. I don't know which cap that was actually bad but better to replace all of them instead of trying to narrow it down to one. They're all the same age so if one is bad, chances are the others will also go sooner or later.

Cheers......

Re: Acer S231HL LCD LED Monitor - No power



I have now taken my S231HL apart and on those two power/signal input boards I only see four electrolytic caps as listed below:

4.7uF/100v
100uF/50v

470uF/10v
220uF/25v

There is no 33uF/100v. Maybe you meant 3.3uF/100v? If that is so then it's possible that Acer could have upgraded that cap to 4.7uF in their later runs of this monitor.

I'll replace these caps and will post the results if that fixes the problem of no power at the monitor. The power supply...

Hi Crajax, Do you remember which cap it was that you replaced, the C number and which board?

Thanks...
