The problem with my BEEprog programmer is that it successfully reads every chip in the ZIF socket but can't program or delete any chips.I tried several different chips to delete or program but without success!It can't even delete and program serial eeprome 24C series!
Everything works properly on the ISP connector!

When I did the self test for ZIF I got the following:

Does anyone have a solution to this problem?
