With the 3 boards connected and some of the ribbons disconnected inc LCD and
backlight but not necessarily its inverter if inside that unit and "viewer"
n/c but CCD connected.
Gradually increased to 3V and 1.83 amp consumption on 2.5 amp limited
supply, so now check a few voltages and then reconnect everything and try
again

Don't forget that there may be high initial current for housekeeping.
Several cameras that I own, when you install batteries, do a shutdown
cycle immediately (retract lens/or cover it, etc.) to put the camera
in a known state.
