T46G no LCD display, MWI light solid red at power up

[tima]

Hello,

So we had a relativly new T46G (< 3 months old) one day at a doctors office (in her personal office so doubtful it's physical problem) stop responding, shows no LCD display when plugged in and MWI (top right light) solid red at boot up. Pulls no IP just dead.

Any suggestions? This is our first actual failure of a phone from Yealink (so far been very reliable phones) so not even sure on warranty procedures.

Thanks,

Tim
