Both of these power up, but each have something going on that I’m camera savvy enough to fix.

The RDC-5000 comes up but the screen doesn’t ever seem to lock in. (It flickers and doesn’t ever come to the menu)

The RDC-5300 powers up and the screen works great but displays an error message and won’t flip over into camera or display mode.

Both appear to be in good shape otherwise.
