sony trinitron help please?

Dear Howtomendit,
I was given this TV (Sony Digitla Trinitron: Model No. KV20DX30U) but with no remote control or instructions: I purchased one of these "does any TV" remotes but it does not seem to work and without the original remote, it looks like I cant tune in the channels in any case ?
Is it possible to tune the TV without a remote, or buy a replacement remote / get the original instructions ?
It does show up BBC1 etc but no picture whatsoever ?

Do you have any other suggestions.

Many thanks,

Congo
