I get this problem too, usually I just punch the moniter(not on the screen part) until the screen comes back. its pretty effective but annoying to do every few hours.

A blinking blue light indiactes that your power-inverter board is not
putting out what it should. It needs an overhaul which may be a simple
as changing out the capacitors on the boards.
It could go beyong that to transistors or even a bad bulb.
It will have to be opened up to do that.
A picture may show visual signs of damage. If you can take one and email it to me , I'll take a look.

SOURCE: Dell Blinking Power Light
There are 4 transistors that go bad due to various issues (one being a cold solder issue with the power inverters for the transistors. I had this fixed and replaced the transistors. They lasted about 10 months). The 4 No. 2SC5707 transistors must be desoldered and removed, new ones put in their place and resoldered. I took the parts (transistors) and the removed power/circuit board from the LCD to a tv repairman and he did the repairs (de and resoldering) for about $60.

some transistors on the board have shorted they supply power to the inverter to run the lamps, they power is not cut off intermittently and the protection circuit has stopped the monitor. the fix is here

Tips for a great answer:

A solid green light means the computer is operating normally.
A solid yellow light indicates the power supply is operating normally but the computer is not processing data.
This could mean there is a problem with the CPu or another component on the motherboard.
((A blinking yellow light indicates the power supply is receiving power from the wall, but not functioning properly.
This generally means the power supply itself is bad and should be tested or replaced.))
A blinking green light means the computer is in standby mode.
You should consider visiting Dell Support and downloading the manual for your
your Dell computer. So use the LED power light codes if your Dell computer has them.
hope this helps
