It sound like a short circuit. I had this problem with 1907FP model. It had an USB port on the monitor which got damaged and it was shortening to the groung. In your case it might be a bad internal power supply board.

It's most likely a couple of the eletrolytic capacitors on the power supply board. This type of cap can go bad over time, and that would lead to the symptoms worsening over time like yours has. It's mostly likely a couple of 10V, 100uF caps in my experience. They should be easy to identify: they will be the ones with the top bulging upwards. Replace those and you should be good to go! If there aren't any bulging caps, just replace all the 100uf caps. (there should be no more than 5)
If you attempt this yourself though be carefull: any caps that haven't gone bad can hold a charge even when the monitor is powered off. Depending on the capacitor of the cap, accidentally contacting the leads on a charged cap can be anywhere from painfull to dangerous! A preventative measure is using an insulated handle screwdriver, short both leads of the cap together on the backside of the board to drain the cap.

You may have bad caps (leaking/bulging tops) in the power supply or blown fuse. This is what the board looks like.
