Cisco 7911 No Screen coming up.

[abdul201388]

Hi there,

I've got a 7911 Cisco IP Phone, I haven't used it for a quite a while, so I decided to use again. So I plug in the power adapter, it boots up normally, the lights light up. Once the lights finish flashing, nothing comes up, not even the Java logo.

I've tried doing pressing the # button following the numbers: 3491672850*#. Nothing happens.

Is the LDC screen not working or the phone is stopped working?
