Count me in,
Lost backlighting yesterday, Got it back after reset.
Touchscreen still worked.

Lost backlighting again today. Put it in charger, tried after a few hours,
and now it worked.
Touchscreen still worked.

I have loaded the latest firmware, and I experience one other issue:
I sometimes now get an audible feedback that I've touched a key,
but no response from the TV.

Also, I'm a bit worried about the announcement of the new remotes;
Why announce them at all? that have to hurt he sales of the existing ones,
but maybe that was the whole idea.

Philips possibly have discovered a hardware issue remedied this with
a new product, and try to halt sales of the existing ones to minimize
warranty claimes.
And atleast externally, the new model brings nothing new to the market.
