I have a question about a monitor. I ibm monitor just went blank one day.. so I took it off and put another on..I then put it back on about 6 months later. It still didn't work. in my anger of having to buy another monitor i hit it.. well it worked again. work fine all day long then shutdown. rebooted the next day and nothing...even after a few smacks. Any idea what might be wrong with it. I got a new baby so money is short.. Wanting to try to fix it my self if something simple.. Do have some elctronics experience. but not sure where to start.
