Six to seven years is about the usual life of a picture tube, and then you start seeing signs of aging. Poor focus is one common symptom (the loss of crispness you noticed). There is an internal focus adjustment, but it usually can't compensate for the tube. If you want to try it, the control is on a part called the flyback transformer. It's usually found on a rear corner of the circuit board, and has a red wire going to a rubber contact cap on the picture tube. Most flybacks have two little knobs on them, and you want to tweak the one marked "FOCUS" a little to see if improves the picture. BE VERY CAREFUL! WITH THE POWER ON THERE ARE POSSIBLY LETHAL VOLTAGES EXPOSED!
If the focus adjustment doesn't help enough, it's time to look for a sale on an LCD monitor. The prices have come way down, and eBay is a great place to look for deals if you don't want to buy new.
