You might also want to swing past the 60xs955/55xs955 avs forum. There's a guy in there who claims to be able to rebuilt the OBs.
He may, or may not, be able to do yours if you decide that the tv is worth saving.
Caveat time. I don't own my 60xs anymore, never had any issues and have not used this service.
Edit: This guy, in this thread:http://www.avsforum.com/avs-vb/showt...4#post18501074
