So I'm pretty sure I have it nailed down to the backlight on the screen is broken. I have tried it via PoE and CP-PWR-CUBE3 and it still powers up and I am able to see what is on the screen if I tip it at just the right angle. But otherwise the backlight is non-functional. I have also confirmed (by tiping the phone to just the right angle to see) that the brightness bar for the phone (when power cube is used) is all the way up.
What I'm curious about is.. what do I do now? I got the item used and I'm not sure I could get a refund. Basically I'm begging for the possibility of information to change the backlight. I hear on many lcd screens they are able to be somewhat easily changed so a whole new unit doesn't have to be purchased.
Thanks a bunch!
edit: or maybe just some more ideas on what to try. seems strange that the backlight just craps out.. I've never before heard of such a problem with the 7970 or an LCD (such as monitor or tv)
Correct, with the reset sequence, you cannot hardset TFTP, because the phone will use DHCP exclusively.
The phone will do all by itself once DHCP reply with option 150 is provided. TFTP32 has a nice log window that allows you to monitor both DHCP and TFTP progress.
