My Soyo 24 monitor that I bought last year at a geeks deal has just died on me today.
Its internal power supply, which most likely is a problem, M24E14 great wall, is nowhere seems to be found but the taobao.com web site.
The zener ZD1 has burned out therefore likely some other components dead too.
Solved by substitution a USA made generic PSU that has required voltage.

I replaced (adapted) the ZD1 with an axial 30V 1 watt zener diode (to prevent overheating) and it worked like a charm, just watch out for polarity when replacing it. I also replaced a couple of bulked top caps under one of the heatsink.

I hope this will help you as well

Regards

Summary: can't get solder to stick new zener diode in place.

Would someone knowledgeable with electronics possibly be able to help me. I took apart my broken monitor (one day just wouldn't power on) and saw charring near my zener diode. The old one pretty much fell off on it's own and I cleaned the area with Isopropyl alcohol and ordered a new one. I received the new one and attempted to solder it on, but my solder would either not leave the soldering iron or just basically disappear. I wanted to verify this would even fix my problem so I taped the zener in place and my monitor booted right up, which it wouldn't previously do. I know I need a better hold than tape. What am I doing wrong that I can't add solder to this spot on the board?

Thanks in advance for any help for an electronics newbie who'd like to learn something new.
Use a good amount of flux, so that the solder can be applied well to the contacts.

did you ever get rid of the monitors?
does anyone else have dead one?

I have 2 of these where the PSU was replaced in each and the first one is now dead again. I am not going to fix it again unless there is a quick and easy way-just not worth it to me.
Anyone want it?
