RCA VLT385 VHS - possible internal damage?

[ComboCompact]

Generally-speaking, how worried should I be about damage/misalignment of critical moving parts if a VCR has been dropped (hard)?

Purchased a RCA VLT385; Hitachi-built, I think, c. 1985. Was shipped to me poorly packed (no cushioning) and sustained enough impact to smash a corner of the case. Powers on/ accepts cassette/ plays & stops, although motor doesn't sound healthy. Play doesn't seem to move any tape and Stop apparently just shuts off the motor, winding down slowly without braking. Haven't been able to check output or open it up yet though. Hopefully this weekend.

It's possible these were existing issues... but given the shipping debacle, I'm curious as to how susceptible the innards are.
