Problem with E-420

I wonder if anyone has come across this problem before?? I have bought a second hand E-420 as I wanted it for all the spares and extra lens it came with.
It arrived today and on using it, I found that when u look through the view finder, what you're looking at is blurred. When you take a picture, it shows clear and crisp on the LCD screen but looking through the view finder, its blurry.
Is this a fault that can be fixed relatively cheaply or would I be better off returning it?
Id appreciate any advice anyone can give me.

Thanks alot

Have you checked the diopter adjustment dial on the side of the viewfinder? If that doesn't help, the diopter adjustment lens might be stuck, jammed by a bit of dust or similar...

Oh dear Stewart, I feel such an idiot!! Why didnt I think of that myself!
Thankyou so much for replying, you've made my day =)
