Cisco 7961 goes in boot cycles with blank LCD display
Posted on 2009-12-27
I've searched all over and all solutions doesn't apply to my situation. I had a working Cisco 7961 and during the process of doing a factory default in went into a state where my LCD has no display. The phone does attempt to do self resets every so often. I can tell it's rebooting itself because the buttons lighting up (headset > Mute > Speaker) and I see this in my wireshark capture with boot up requests.
I've tried the usual factory reset button combination but doesn't seem to help.
I attempted to load up the required bootup files (xml, cnf, images, etc) using tftp32 with dhcp and tftp configured but the phone doesn't seem to register. Perhaps my files and setup need to verifed here.
The only thing sort of me trying is consoling into the phone since i don't have the required cable to do this.
I am looking for help how to bring my phone back to life. This is to be used on a SIP firmware on a Fonality IP PBX server. I have 4 other 7961s and I'm afraid to try again on another phone.
