My ADP-054 was working fine earlier today however now it refuses to get past 3% on 27C400 it's always the same address and the write is off by 8. I am using a power supply with the GQ-4X and as stated it worked earlier today, I was able to program about 24 chips without issue. Blank checking works fine but writing does not.

Some examples:
Chip is blank
ID check skipped
Writing... Buffer
Elapsed time: 2.34 seconds.
Write failed, Address=0x00402D, Buffer=0xEB Device=0xE3
Write failed

And with a smaller chip - HN27C4096

Write failed, Address=0x00000B, Buffer=0x88 Device=0x80
Write failed
Different file but HN27C4096
Write failed, Address=0x000003, Buffer=0x0B Device=0x03
Write failed


I know it isn't the chips because I tried almost 20 different 27C400 and all failed at the same exact address writing after passing a blank check. I was able to program the HN27C4096 with my cheap chinese TL866 fine.

Any ideas what may be going on? J1 is set to the first position.
