[rachmach]

when i want to read it displays a message (device insertion error bad contact at pin 1.2.3.5.6.7.8 )
I reverse the eprom but the same problem
I tried with another XPROG and it work perfect

check all zender diodes, and 5V and 3,3V stabilaizers. if all is good, your atmega is fried, but i think it will can be 5V or zender.

OK my freinds how to chek it ??

[andrius]

there are two 3 leg chips near power in, ech is there 5V and 3,3 V stability. then chek the diodes that are near the small 8x2 pin output, they all should not have 0 resistance.

ok tankh's i wil chek and report
