Hi,

The remotes I get for the KV20TX11 television are the RM-765 or
(universal) RM-Y133 neither of which I get references for on the Sony
site. I would call Joseph Electronics in Niles, Il and run your model #
by them. Their phone is 800-323-5925 and if you're a professional,
aren't we all, you'll get the pro discount.
