The componets(quartz, capacitors)were measured before instalation and are OK. Quartz were tested in a test oscilator and its freqency were measured with a frequency counter. Capacitors were measured and it has the specified value. After I write the program into PIC I close the IC-Prog software and open it again. Reading all from the PIC I compare this with the program from the file and is the same. More, on a clear buffer of IC-Prog I load the program from the .hex file and aftef that push the "verify" button. The result were OK. I understand that using this function(verify) it verifying if what is displayed on that buffer is the same with what it is written in the PIC. Regarding solderless breadboard, I measure the continuity between its legs and the PIC legs, each by each and is OK!

The main reasons for the oscillator not working are: - wrong components - wrong connections - wrong settings in the configuration fuses If you clear the ic-prog buffer and then read the chip, does it then show the 'HS' oscillator setting selected? And again about solderless breadboards: do you realise that the common round-hole types have a break in the power rails?
