First ensure that the mouse is on if not press the restart button on the bottom of the mouse to turn it on. If the problem still persists try restarting the computer if that does not fix it you will have to clean the scroll wheel or your scroll wheel is broken ad you will have to replace it.

There was some kind of vaseline inside the scroll wheel covering almost all the holes in the scroll wheel's side. There is photo-transistor detecting those holes moving during the scrolling.
I put paper towel under the scroll wheel and gave a good amount of WD40 into scroll wheel interior. Next morning the wheel was clean, all vaseline along with WD40 soaked into paper towel under the wheel.
Assembled the mouse back and it's working nice.
Update: after 4 months it's still working like the new thing.

This answer is not specific to one Logitech model, and should work for most mice. The scroll wheel on an older mouse can stop working because there is simply too much accumulated crud inside that stops the wheel from functioning correctly.
You can open the mouse by taking out the 3 or 4 screws (Phillips); they are usually located one or two under the battery(s) and another two under the glide pads under the mouse in the front. You can peel the pads off and stick them back on after reassembly. If the pads are really old and thin, then feel for the hole underneath and puncture them to remove the screws. The remaining portion of the glide pads will still work afterwards.
Now carefully open the mouse and lay the cover to the side, leaving the wires attached. Look at the scroll wheel. If crud is the problem, it will be obvious.
Now clean the crud away using tweezers and or a toothpick and then to finish off, a bit of compressed air. Reassemble the mouse. There is a very good chance that you won’t have to buy a new mouse!
I have uploaded a couple of pictures to show the problem and to show the result with the “tools” used during the cleaning process, but I am not sure they have loaded correctly!

Sometimes when the mouse is dropped, the motion sensor of the wheel get misaligned. if this is the case then realigning it carefully, which may require some trials, may resolve this issue of no scroll

Lubricant was covering the optical slits in the wheel of my mouse. I cleaned the lubricant off slit area using cue tips wet with alcohol.

My mouse would scroll down, but not up. Discovered there was dust in the slit just below the wheel on top. Sprayed with canned air and now it works fine!

Worked like a charm thanks, I was about to smash my mouse.

saved me a 50 mile trip to buy a new mouse!! Blew the air in the slit (how does this optical slit work exactly?) and the mouse scrolls just fine. Yes, my desk was a little dusty.

I'm so glad these answers were still up. I would never have thought to blow into the optical slit, but it worked perfectly!! Thank you so much!!!
