I found this explanation from someone who appears to think they know
why it fails:

"it is the brain/micro/audio/video processor board it is what makes
things work in the set. I have replace the board 100x for this exact
problem and every time it has fixed the issue.
I doubt many people have explained why you have had the problem but it
was no fault of yours or even of the LCD itself, it was a design flaw
of the remote which was not a fine tuned frequency and confuses the
microprocessor and makes it think it has been told to do something it
shouldn't have protects itself. The remote was built with the
frequencies not set properly at the factory and when it got bad data
from the remote the micro blows on the sets main board. I have spent
weeks trying to bypass the data line no go they connected both the
buttons on the set (less the power button) and the remote buttons on
the same data line. There is only one fix brain surgery replace the
brain with a new brain and replace the remote so it does not dameg
your new brain. The new board comes with new software and new coding
on the remote,"

A common fault is the main processor, or in the I/O circuits that work
with the main communications buss. *That is why the board is replaced.
It would not be feasible to service at the component level.

Funai isn't stellar, but this failure is a bit too common for too many

component level, of what fails in these sets.
