Sorry I don't know the chassis number on this TV. I need a part number for the RF input (box) connector and where I could purchase another one (in Canada if possible). I tried another RF input box from another chassis (not a Sony) and the TV worked fine when hooked up to a VCR (RF) output but it didn't work hooked up to cable. I've had success in swapping RF input boxes before, am I overlooking something here? Any input would be appreciated, thanks.
