I've been searching for a solution for a while now, so I don't think a solution has been previously posted for this problem.
I have a SoundPoint IP 550 that is completely locked up. On boot, the screen backlight turns on and all lights light up (except for the top-most programmable key on the upper left of the phone). There are no messages on the LCD screen, no sounds, none of the lights blink and it just sits in this state indefinitely. It's not that a message shows on the screen and then the phone goes blank; it's that the screen starts out and stays with no pixels on the LCD lit up. It doesn't acquire an IP address from my DHCP server, so I can't access it over the web interface either.
This happened randomly to this one phone (I have about 100 others that work fine). It wasn't dropped, I wasn't updating the firmware or configuration files, and there's no cracks or other external damage.
I've tried booting without the handset, network, or anything other than power connected, but it doesn't change anything. I've tried rebooting with the reset key-combo (4,6,8,*) but this makes no difference.
Does anyone have any ideas on how to get past this? The phone is long out of warranty.

This sounds like a defective unit and only the official RMA process would get this back or exchanged as this sounds like a non field recoverable issue.
