Hi and welcome to JustAnswer,Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially, a bit of a challenge sourcing the remote for a Panasonic RX-D50.
Still, would "used" be acceptable? ...from another country? ...thus would include shipping?
And would a link to an online source/seller serve your need then?
Please post back how you would want to approach this and/or should additional information be needed.
