Hi:

I have this set, about 3-1/3 years old, used lightly.

About a year ago, HDMI 2 stopped working. Yesterday, HDMI 1 and 3 died.

A Panasonic Blu-ray player connected to any of these returns U72 or U73 - "The
HDMI connection acts unusually. The connected equipment is not HDMI
compatible.".

This had been working fine. The only thing that works through HDMI now is
that the player turns on the TV and switches to the connected HDMI input,
which is blank. After a few seconds the player displays U72 or U73 but it
continues playing.

Composite, Component, and the Tuner still work.

Google returns a variety of problems with A/V inputs on Panasonic TVs
but besides replacing the "A" board ($$$ and who knows if any given version
will be compatible) or resetting to factory defaults, I haven't seen a
solution. I have umplugged the TV for a few minutes with no change.
I'm reluctant to do the Factory Reset but will try that if necessary and
there's a chance it will work.

Thanks!
