When my Syncmaster 204B (used as Monitor #2-1600x1200 60 hz) goes to sleep I can't get it back on. Power off/on, replug etc. every now and then it comes back. What's up?

most likely either the plug going into the monitor or outlet is not connected properly or the outlet is bad if it was just working and you have not had any surges

Hello,

If you are talking about the power light flashing and no picture then its not in sleep mode, the power supply has failed.

I suggest the power supply inside the monitor is bad.

Check the data and power cables. One of them might be loose.

Got the same problem, happened yesterday for me, Did some research and it looks like its bad capacitors in the back, check out this page for more information... i'm taking mine to an electrician to fix today... luckily he's related and should be able to fix it on the cheap...

Have you tried to plug it in else where?
If you did and still same problem then from what you said I was hopping that it wouldn't be your problem, but you will need a new monitor.

If you know how to open it up and get to the power supply you will find three capacitors 2-820uf and 1-330 @ 25vdc 105o.they will have puffed up tops replace them. FYI the monitor has a 3 year warranty.

Yes. There is no vertical deflection. The circuit that controls vertical deflection is bad. This is an easy fix for a TV tech. Take it to the TV repair shop.
