    I was having a similar problem with my new Samsung. Sometimes it seemed to work fine, other times it did the flashing on and off thing. It seems that my refresh rate might have been the problem. I had it set on 75 htrz. I changed it to 60 and so far it seems to be doing ok. I don't know if it's a problem with this monitor or what...

I had the same problem...apparently the Syncmasters have some caps that are known to go bad pretty often. They will show visible swelling on the top with the slits. If they are flat they are probably good. The 820uF was too hard to find so I used a 1000uF with the same voltage. I had two caps blown on two different monitors so be sure to check them all. Hope this helps. Check out pics on BadCaps.com

Hi
I repair quite a few models of monitors and in MOST cases when a monitor goes to sleep, the light becomes a steady dim amber color.
If they flash that is usually an indication the the powerboard is not putting out enough power to run the unit or there is a problem with the inverter board.
It will more than likely have to be opened up to determine the problem.

Dell SE198WFP 19" LCD won't come out of standby


I went into the BIOS (with F2 during restart) and changed a value -- IIRC it was called something like "power management scheme" -- from the default S3 to the other choice, S1. Now the old Dell XP Dimension 2350 will go into and out of Standby correctly and the new SE198WFP 19" LCD will too.

My Samsung SyncMaster 215TW Monitor only flashes on for a second when I hit the standby button, and wiggle the mouse. I can't get the monitor display to stay on. Can you help?


If it is not still covered under warranty, start by opening the case. Once you remove the power board, you will probably notice several capacitors (the round, can shaped parts) that have tops that are not flat. If you see any that have bubbled tops instead of being completely flat, they need replaced. Once they are replaced, the monitor should turn right back on. Hope this helps.
