jdm pic programmer vcc

If this problem is when you use a particular PIC, confirm that +5VDC voltage is ok at the Vcc. That may drop if your PIC is having an internal short and the programmer will give the same error what u are getting. Good luck

how test jdm programmer

thanks for your replay,i have one doubt that my PC is not well grounded,is it affect my PIC programmer? because sometimes it gives good response...........

That MAY affect your PC performance as well any other peripherals you use. Because the SMPS in the PC will have some minute EMI leakages which can be felt on the cabinets and metal parts if a proper earth is not connected. This affects the hardrives and also gets transfered to the PIC Micro through the ground of the serial port. And rememeber, the PIC is highly sensitive to EMI and RFI. Good luck.
