Camera won't charge battery

With camera in the charging cradle, the battery doesn't charge.

The blue indicator light does not come on.

However, when I turn the camera on, the camera comes on normally.

With camera NOT in the charging cradle, it does not come on.

These symptoms are identical with two batteries, so I believe the batteries are not the issue.

My conclusion is that the power supply and cradle are operating properly. The problem must be within the camera itself. Agree?

Several have posted this issue; I've seen no cure. Is there one?

Is there a repair manual or schematic available for this camera?

Thanks, Keith
