Advice on melabs programmer

[peterdeco1]

The PIC's that are programming properly are 8 pin 12F629, 12F675 and 12F683. The 28 pin PIC's programming properly are 16F73 and 16F872. It's only the 16F819 that doesn't work.

Is your pic16f819 the 18 or 20 pin version? Check the data sheet. The programming pins are not in the same location. Your mclr, PGC and PGD need to line up in the ziff socket. If you are doing in circuit programming check your wiring again.
