Problem with the programmer PCB50B

[lamer666]

Hello.
I bought a programmer Willem PCB50B. Everything works fine, but at one moment there was a problem: when reading the Electronic ID, programmer allways show "Fujitsu".
I try to read bios chip, it's shows empty, although this chip is runs the BIOS and boot PC.
In what may be the reason? Please help.

Check chip pin contacts in socket.
Try to check another chip on programmer.

I checked chip pin contacts in socket.
I pulled all chips out and put them all back to chip sockets.
No results.

Do you apply correct socket , lowest for FWH/LPC ?
Are you able check any other chip, even flash or EPROM in ZIF socket ?

Do you apply correct socket? Yes! We use FWH/LPC to programm bios chip.

Here is the test with bios chip in socket:




We do not have other chip (flash or EPROM) to check then in ZIF socket. But i sure result will be the same.

Apply jumpers in PCB45(PCB50) mode with SW 0.98xxx.
In picture seems PCB35mode. Check in PCB35mode with 0.97ja
Go Test H/W mode and check all signals one by one with multimeter.
