Well the reset on your dog probably won't work so it may eat another remote.

On the tv when you use a universal remote you enter a code for the remote. this lets it talk to the tv and should give you the same access to menus ie setup as the original. I don't see a tv model but when you get the universal it will have a list of all the codes. You just look up your manufacturer and then look for your model and enter the code. There may be a few codes per model so you just have to try each one until it works. Unfortunately for some off brand tv's the codes don't work but they are quite good for most. Your other alternative is of course getting a oem replacement.

And even with out a remote you can usually access the menus by pushing the buttons on the front of the tv. Its slow rather frustrating but should work if nothing else.

Page 61 of the manual shows how to bypass the pin if the pin number is forgotten with the remote, however you need the factory remote as a universal won't work. If you knew the pin number a universal remote would work to enter the numbers, but i'm guessing that you don't know the pin number in this case and there is no other way to reset it without having the original remote. These monitors were made for commercial use and have a pin lock to protect the settings in from being tampered with in a commercial installation.

Try website like Remotes.com to buy the original remote.Any universal remotes is find,but getting ur tv codes to work on ur tv universal remote are 70/30%,u want to tries with the univeral remote,it up to u.

If you get an universal remote, you won't have all functions to control the TV. Moreover, the codes for many audiovox model are often not reported on universal remote manuals , therefore you may need to use autodetect feature on universal remote.

The best choice is buying a replacement original remote like the ones below:
