Dh pip board for Panasonic PT51HX41E

[wonderelectronics]

I'm trying to get the TNPA2033 or TNPA2033S (DH PIP BOARD) for a Panasonic PT51HX41E, but every electronic store on the web I visit replies that the part is not longer available. Does somebody have it? Or can someone refer me to a well-known electronic store? Thanks...
