My neighbor has a Samsung monitor sycmaster 932a.
 When the computer has been on but idle for a few hours it takes a very long time to come back from "sleep." Usually, the touch of any key  will bring it back.  But now it stays black for several minutes,and the button light keeps blinking until finally it stays on. From that point, everything is as normal. However, it now it has stopped turning on.
I switched monitors with him and gave him my spare.
 
Now it does not turn on at all. The button keeps blinking, no matter what computer I plug it into. What I thought was a problem coming out of sleep mode turns out to be a bad monitor. Is there something in the monitor I can replace to fix the problem? Or a way to reset it?
It is an expensive monitor.
Thanks for you time.

OK 3 days later, 47  views, and no helpful posts! So here is what I found from researching this and watching  a few videos.

I hope it helps others, since I hate it when I find someone who has the same exact problem as mine and when I click int the forum there is no answer.

So here it is:

 

The monitor has a 3 year warrenty, and on the samsung site it will tell you when it expires, this one expired in January....damn back in January we though it had trouble coming out of hibernation.

That is my first tip. Shut off hibernation and see if the monitior still has a problem turning on, and check warrenty immediately!

 

The samsung site is not user friendly and I kept going in and out of tech support, so finally gave up. I googled it and found that Samsung TVs and Monitors have a lot online about this problem. But nothing specific about the 930B.

So after watching a view videos I determined that it was probably bad capacitors.

I watched a video of prying a monitor open with a butter Knife. So I did that and it came apart pretty easy. Then I unscrewed a board and saw that 3 capacitors were bulging and leaking.

I should put some pictures up so it will be helpful to others. I watched a video on changing caps for $1 each and while it looked easy, I was concerned about the high voltage, so I decided to put the card numbers into google and replace the card which was easy to get out. Although I could not figure out how to pull the metal box with the card it it, from the screen. However, it wasnt necessay since I could unscrew the card. I ordered the part from ebay for $25.

If I'd noticed the topic, capacitors would have been my suggestion. Thank you for letting us know how you resolved it!

Yes there were 2 bad capacitors on the board with the power, I switched that out and ...wha la fixed! for $25.

I took pictures and I might put them somewhere because I did not see anything for my exact monitor, to help others.

thanks

Jan
