iPAQ 4150 Board Level Schematics

Hi all,

having an IPAQ 4150 with a defect backlight only, I wonder
if there is a schematic flowing around. I would like to
see if there is a inverter for backlight that could maybe
being damaged.

Any Help would be appreciated.
Best Regards
Markus

You don't need a schematic to determine if the inverter is working.
Measure the output to the CCFL or EL. CCFLs in these appliances
typically have strike voltages around 300-400V.
