Just bought a replacement for my CX that sprouted legs. I got one on ebay, and it is in great shape. Except for this little problem. It will not turn on after it has sat in the off position for 5 or 10 minutes. The only way I can get it to turn on is to drop the display end 1/4 to 1/2 inch onto a hard surface. Then it turns on fine and the weird thing is that you can turn it off and on as many times as you like, as long as you don't let it sit for a while. Then you have to drop it again. I have not opened it up yet as it is useable, and I wanted to get some second or more opinions about the possible cause. Everything else seems to work as new.
TIA for the help.
