HP 23es monitor will not power on

[unclepax]

Yes, I have read the postings but cannot find an answer that solves my problem. Please help. My almost one year old HP 23es monitor has stopped. Won't power on. Tried 3 different PCs. Both the VGA and HDMI settings worked fine when it worked. I tried 3 diff laptops, Win 8.1 as well as XP and Win10 64 byte. I have unplugged, rebooted, changed the power cord top the power box (from wall to power box). The power light IN BACK of the unit does light. The power button in the lower front right corner doesn't do a thing. This all started (I think) when I got the display would go blank and then reappear, over and over again.  Helpful hints would be appreciated.
