I purchased a second hand Soundstation IP 5000 that was working fine but I didn't have the Admin password and 456 was failing and factory reset it using keypad and mac address successfully, but then everything stopped working. :(
Now when it boots the LCD backlight lights up but doesn't display anything on screen.
I can access it via the web UI and have been able to upgrade the firmware using the Polycom online updater but the screen hasn't come back.
It registeres fine with Asterisk and I can dial a number and that works fine.
Any suggestions on how I can bring the LCD it back to life?
