Should I clean the inside of my crt tv or just leave it alone?

I had my 36" tv sitting outside while I was painting the inside of the house and a small leaf about half a centimeter fell on top of the tv. When I brushed it off it fell through one of the slots on the top of the tv. I shown a flashlight through the vents and it is near the front of the tv near the speakers. Should I pop the back cover off and blow it out with one of those pc duster things, or just leave it in there?
