I have several 7970s hooked on  to a cme router but on one 7970 the  screen is blank it is only visible with a high powered torch everything on this phone works great except for this problem, even when it powers on the splash screen can only be seen with a torch.

I have used two reset codes the 12134.... and the 3491..  still no luck.

Any help is appreciated.

    Sorry, no. Try google it or search on eBay.

    I usually advice my customer to purchase Cisco support for 7970 phones. For $8/year, it is a good deal for protection.
