I am a lead mentor for team 7504 troubleshooting this for team 1099
After applying power, none of the LEDs light.
The unit draws ~100 mA.
I checked the voltages at:
F4 and it is good 12V
R897 (current sense) 12V
C297 + side 5.12V
C227 + side 0V
C322 + side 1.5V
C336 + side 1.8V
C469 + side 0V
C211 + side 6V
C137 + side1V
USB connectors, pin 1 0V
PN 155213D-01L, SN 306CE31
Any help will be appreciated.
Is a schematic available?
Thanks,
Steve
