pin

hello i have a pansat 3500s that does not power up so i checked the power board with a mulitmeter and power is jumping or fluctuating e.g. on the 3v pin the power jumps from 1v-3v on the 12v pin 6v-8v-10v-12v on the 23v pin 28v-33v-38v on the 6v pin 8v-12v the last 2 pins the volts are higher...

How do I reset the PIN in the service menu on an HP 4600n printer?

I just loaded my new B75 boot and when i go into Parental Controls...i get the Change Bin popup....it has Old Pin, New Pin, Confirm Pin. When I type 0000 for old pin and enter a new pin...it keeps asking me to change the pin. Anyone else getting this?...need help..thanks!
