Hello Harry

Try resetting and re-pairing - see the attached manual page.

tried that ,does not bring the screen display back

In that case, regretfully, I think you're looking at a new unit.

IMHO it's unwise to replace just one of the pair. The software might well not be fully compatible, and you'd have no in-warranty support. And you might even struggle to find one of the pair without the other. Go for a new matching set.
