Agilent DSO3000 Power Supply
« on: February 22, 2024, 07:33:26 pm »
Hello Everyone,
I know this is a long shot, but figured I would give it a try.
I have an Agilent DSO3102A that does not boot. 
Buttons light up, fan spins up, and the back light for the screen turns on.....but that's it.

I wanted to verify the voltages coming out of the power supply, but am not sure what the proper values would be. 
I did see some values that seemed odd, but don't have much experience with these.

These are the voltages I saw when I probed the pins (order is from front of scope to back of scope).

Pin 1: +5v
Pin 2: +5v
Pin 3: GND
Pin 4: +17.69v
Pin 5: GND
Pin 6: +7.95v
Pin 7: -7.97v
Pin 8: GND
Pin 9: -16.85v
Pin 10: GND
Pin 11: +30.78v
Pin 12: +155mv

I could be wrong, but some of the voltages don't seem right.
This was tested under load with the main board connected.
If you have any thoughts or suggestions, or better yet if you have one that you know what the voltages should be, I would greatly appreciate it!
Thank you in advance!!
