CURSOR AINT GOIN DOWN .......!

Is this str8 4ward 2 fix?
as the switch just aint going down, is this a popular prob on the 2000xl?

you can try to blow the switch clean with a can of compressed air. or just buy the new switch for 5 bucks at vst. and replace it. and if it doesnt respond at all. you will probably have to replace it.
