I have a bush TV video combi and need a universal remote code. The model is BTV18 SIL, could anyone please help, thanks

What you will probably have to do is to purchase a "Universal," or
"One for All," type of remote control. These types of remotes come with
Long lists of several remote codes for each of many different brands of televisions.

However, you might want to make sure that Bush is one of the brands
That the remote can operate before you buy it. You should either ask
The salesperson at the electronics store and even ask for a demonstration
Before buying it, if Bush tvs are common in your area/country, etc.
