Chances are if you wish to change from vcr to tv viewing, that it will be a software switch and not a hardware switch, i.e. upon receipt of the signal from the remote control's TV/VCR button or the non locking TV/VCR button on the front panel of the player the control unit will change the mode from the vcr as the signal source to the antenna as the signal source.

Chances are if you wish to change from vcr to tv viewing, that it will be a software switch i.e. electronic IC component being turned off or on and not a mechanical hardware switch, i.e. upon receipt of the signal from the remote control's TV/VCR button or the non locking TV/VCR button on the front panel of the player the control unit will change the mode from the vcr as the signal source to the antenna as the signal source.
Have you checked if the TV/VCR button on the control panel works in case it is a faulty button on the remote control?
If you meant to change how something else works then again it most probably is done by operating software switches and not hardware switches or relays etc
