Dell 22 inch Wide E228WFP Analog Flat Panel Monitor monitor goes off and i have to turn on again and it may stay on for a good while and then sometimes i have to constantly turn it on over and over until I get through. screen shows monitor okay

First place to check will be the caps in the power supply/inverter board.

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.
