My son pulled my playstation 1 off the table and it hit the floor hard. Since then, the playstation loads up but it stops at the insert game phase?? I have tried CDs and they work ok, so it is just running my games?? I have cleaned the len but still no change. It was in good condition and well looked after prior to its fall.
Any ideas would be appreciated.

Cheers
