Jim, Al I don't think so. I is on the back of the board. That was the first
thing I checked when I saw that. You can even see spots on the top of the
plastic that houses the RCA and RF connectors. Jim are kidding about putting it
thru
a "pots and pans" cycle? I have dishwasher at home.
Thanks

Panasonic web site shows the board, P/N TNPH0370ADS, with a dealer price
of $458.02. Any chance the stuff that got spilled on the board is
coolant from a leaking CRT? Consider pulling the board a putting it thru
a "pots and pans" cycle, that is if you own a dishwasher. (Some of us
can's affort one!:)
