problem with my 21inch mitsubishi Help?!

[Sigma]

I have a 22inch diamondpro 2020U. Ive had it for about 4 years. A coupe of weeks ago the monitor turnied on but no picture whatsoever. I just gave it a tap on the side and then it began to project a picture. This morning the same thing happened and it just wont project any image or anything or anything. I hoooked up my other monitor from my other cpu to the cpu running the 22 inch and it worked fine so its a monitor problem. Is there any way to fix this thing or it totally shot? Thanks for your help.

some places can fix this sort of thing or at least have a look at it...
if it's a problem with the electron gun inside could be expensive or could be cheap like a transistor...

Trust me I know what I'm doing... ooops, grab the cat...
