None of the codes worked but thanks for the effort!

FWIW, I think the Vizio V-Series TVs must be fairly new to their line. Unfortunately this means that I won't be able to import all the new codes with my old MX-850.

On that topic, my 850 has been superb for many, many years now but it is getting a bit "long in the tooth" as well as having some keys that are working intermittently. So you know what might be the best replacement for the 850 nowadays?

Thanks, Bill
