I got a Minipro Tl866 programmer and I'm using its software Minipro V6.10 to read an Eeprom s93C56 chip and it read fine but, it's giving me a blank screen.

Hi there!
I've had a MiniPro for a while now, and I've had the same problem with some older EPROMs. Is it a windowed EPROM (ie, UV-erasable)? If so, I've found that sometimes it doesn't read them correctly, and it rarely can generate the necessary voltage to program them.
I haven't used that exact chip before, but if you can provide some more detail I can try and help.

If you have Linux you might try qtl866 (which uses minipro as a back end). See https://github.com/wd5gnr/qtl866 and https://github.com/vdudouyt/minipro
It is likely that if it isn't the actual hardware, that software would work. If it is actually something in the hardware, it is probably going to be bad on both sets of software.

I tried it on two separate chips. Both are soldered to the board thought and that might has something to do with it? Between I'm using Window 7 and using a soic clip to read the chip off the board. Maybe I should de-solder the chip from the board and read it that way...

Don't assume you can easily read IC's soldered to the board.
