Blinking LEDs on a Cisco 7942

Hi everyone.

I have a problem with a Cisco Phone 7942. As soon i turn it on, all the leds on the phone start to blinking. The same happend with a external psu and PoE. Is this a hardware problem?

You could try factory reset it

Follow the steps below to successfully factory reset your Cisco 7942, 7962 IP phone:

1. Unplug the power cable from the phone and then plug it back in. The phone begins its power up cycle.
2. While the phone is powering up, and before the Speaker button flashes on and off, press and hold #. ...
3. Release # and press 123456789*0#.

Thank you for your time. I already did that but it wont work. The led buttons and other leds start to blink (all at the same time) as soon as i power the phone without doing anything else. I never have seen this before.
