I have been working from because I'm sick as a dog. Had my laptop connected to this monitor and left it up that was most of the day.

I came back to turn it off after a nap and noticed that my monitor would not show anything. The power button was lit, but switching to dvi and back did nothing. And I could not turn it off with the power button.

So I pulled the power cable, put it back in, and now it won't turn on.

Is PSU fried? This monitor does not use a brick, but a direct power cable, so the PSU must be internal.

Pretty sure it's just dead, but was hoping there might be a way of fixing it.

Thanks.

Its gone. Try to let them repair it. Be aware that your OSD might not work anymore when its back, among other little annoyances.

Good luck.

Samsung is messy.. i think its best (considering your health) to give it to a professional technician.

Thanks guys. I'd rather spend the money on a new monitor, and I don't have it right now anyway.

Unfortunately I don't know how to solder or how to figure out where the problem is. And yes, I'm not up to it in any case.

Will just have to make do. Funny thing is that my old dell 20" 1600x1200 panel that's 10 years old is still going.

Inside LCD TV there is a logic board and a power board.

Most likely it is a single cap on the power board that went out.

If you remove the back and give a visual inspection of the caps, one should be bulging or burst on top and discolored, leaking.

The caps are oriented with a positve and negative side and are marked on the cap and circuit board. Maintain polarity!

All the caps have specs printed on the outside.

Nichicon makes good replacements. guessing about .75 cents for the part. http://search.digikey.com/us/en/cat/capacitors/aluminum/131081?k=capacitor

Samsung has had an issue with certain models. I fixed a TV for a friend, so this is first hand advice.

Digikey.com has parts. http://www.digikey.com/?WT.z_yt_ad_ref=Overlays

Take photo of inside parts for disassembly, so you know how to put it back together.

The other option is to get it fixed...costly, about $200.

or

Take the power board out and bring it to someone who can solder a new part in for you. Order the part yourself.

Thanks I'll take a look when I'm feeling better. Who knows, maybe I can fix it.

Yep, I had a Samsung LED with the same exact problem, it had a single bad cap on the PSU board.

I was too lazy to dig out my soldering iron, so I just ordered a remanufactured PSU board from ebay for $20.

The funniest part was that the new PSU had clearly had the same cap replaced that blew on mine, luckily the ebay seller had recapped it with a much better quality cap than the original.
