Default [SOLVED] Samsung monitor odd behaviour.

This afternoon I went to turn on my monitor (Samsung Synchmaster 275tPlus) and upon pressing the power button ( a soft touch with blue led) nothing happened. no power indicator, lo image nothing. Repeated pressing did nothing.

I checked all cables, UPS, etc and nothing was loose of otherwise abnormal. I played with the button a bit more and a few minutes alter the indicator lit and the monitor came on.

Anybody know if this may be a problem beyond just a failing power switch?

I ask becasue Samsung was in court over a similar issue with 7+million TV's in the US this year and they are the exact same vintage as this monitor (common partds?).

I really don't want to have to replace this right now as it would be very costly.

Sorry to read this ,I have a monitor ( LG 19") that was doing the same thing I had to keep unplugging and plugging back in the monitor and pushing the switch to get it working. Then onday nothing. it totally stopped working, I just unplugged it and put it in my closest hoping to find a fix which I have never found. I really hope that there is an answer for this because I really hate to waste it

In reading on the TV's it was due to some bad caps on the PSU board. replacing them fixed the problem (or replacing the whole board). This is the first time this has happened so I hope it doesn't come to that.

My 953BW's power button sometime would switch the input source instead of powering off and my 940MW would take forever to switch from AV to DVI.

Acted up the same way again today when I turned it on. a bried blink of blue when I press the power button and nothing.

If I push it several times it eventually turns on. :( It's very hard to find a 27" S-PVA 1920x1200 these days :(

The end is near ;( had a monitor do this to me for over a year, then one day got the vertical red line on the left side...3 months later she bit the dust. It was board failure in my monitors case.

I had an old Syncmaster monitor that used to do this too. Sometimes it would give a 2 second beep before turning off the display. Some google search gave me a youtube video that basically dismantled the exact same model to show the blown caps. Let me see if I can find it, though I don't remember the model number anymore. It did serve me a good 4 years though.

It's not the power switch.

The PSU is failing.

Good news is that if you want to do it the Samsung monitors have a very high fix rate.

You any good at soldering?

I had this happen to my old LG monitor about a year back. Would take multiple tries to turn it on then one day nothing but a hissing sound coming from it. I would say start looking for another monitor or PSU for your current one.
