Hey Guys,
So I have two Samsung T240s with consecutive serials purchased together.
One of them has developed an intermittent shut-off problem. I can use it for hours and it will stay on, then suddenly it will shut off (power light is off). I touch the power button and it turns back on, then turns back off again, usually within 10-30 seconds. I can do this several times, and finally it stays back on and keeps working for an hour or two or five again, and then starts doing this again. Sometimes (though rarely), it will flicker off and back on, as if someone unplugged and replugged the power cord really fast (we're talking 100ms here).
I opened it up and checked all the connections, sprayed with contact cleaner, and it still does it. I am stumped. Could it be that it has a bad touch sensor board that tells the monitor the power button was pressed when it really hasn't been?
The second T240 that's been sitting next to it its whole life and which has the same exact number of hours on it does NOT have this problem.
Any and all suggestions are very much appreciated - I'm at wit's end! These have already been replaced by Samsung for the same problem 2 years ago (they were originally purchased in 2008). If I can't fix this, I am going with Dell again, as their monitors have never ever failed me (have 3 2001FP panels that are 7-8 years old and going strong, not even backlight discoloration...).
Thanks!

. If not, does anyone know how much another power board costs and where I can get one? Thank you.
