hi ask for help from anyone who knows

I have wilem programmer has 2 years. I used to program the 27c256 chip and sst27sf256
then there is no problem about the usage because I know the difference between them. EPROM and flash rom

but now when I want to program. programmer is like some little problems. when I check the hardware connection. everything was ok, but when reading the chip. it will display like this

FFFF0000F000FF000FF00
00F00F000F0F0F00F0F0F
00F0F0F0F0F0F0F0F0F0F

if I erase the chip is ok. but if we want the program can not. I was not trying on a chip, but much of what I've tried. but still not successful. I have a friend who believes that the programmer is in service, but I do not know la how his service and want to be part of any service
hope you all can help me
