721 blacking out on screen but recording

To rewind this a bit, I am in Alaska and can not get a good enough shot at 110. For whater reason E* does not put the software or EPG on 119, only on 110. Well I was able to get the software download from a dealer who has a 2M dish and can get a signal from 110, download the initial software and away we go. I have a dish 300 with a dual lnb and both outputs going into the 721.

Everything seemed fairly normal, pause, ff etc. Guide looked good, programing was fine. Then while watching one show while another timer was recording something else I hit PIP and the pip window opens, fills with the main on-screen program goes black. The svideo tv screen goes black and there is no audio. Very curious. I cant swap and if you hit cancel or view the proram banners says "Unknown Record". Huh???? A power down (with the remote) seemed to clear it up. Other PVR functions are working, I can see the menus, call up the guide etc. Then it happened again. The really weird thing is that we were recording DS9 but it went black on the tv. We left it alone till the end of the program and lo and behold, it was recorded just fine. We could watch it recorded, but were unable to watch it live.

It am not 100% sure it has to be recording for this error to manifest. Last night we were watching, swapping between pips and with recall on one tuner and the main screen went black while the pip was on. No swap but a remote power off triggered a system boot. It went through the hard drive verify and acquireing info from the satellite. Appeared to be a full reboot to me.

I figure this could be:
some artifact of my 119 only setup, like can't dl software
no switch, just dual lnd into dual inputs on 721
a bum 721 with heat or other problems (it is in a good spot)

Any thoughts on this one?

This sounds exactly what happened to me, similar things different details, for more details check out the 721 glitch thread..
Here is what advanced tech had me do, (nvm reset)
Go into the system setup and then diagnostics, now hit info.. right ...left
A debug menu pops up, one of the selections is nvm reset, hit it and it will prompt are you sure??
After it is done, (a few seconds I think) hold down power on the front panel (cold re-boot I guess)
Everything should be fine now
As far as what anonymous said about check switch not sure if you should do that after or before the re-boot, I think after will be o.k.
The next morning after I did the nvm reset, the 721 got dumb and lost my SW 64 switch setup, doing a check switch everything was cool..
good luck..
As for anonymous I assume you must be a Dish employee, please feel free to offer any other tips you have with the 721, staying anonymous is fine with me if it helps any of us out..

No, it will change nothing but fix your problems (I only did it the one time, and I wish someone would have told me to do the check switch). I ended up doing it the next morning.
Check switch is a definite, start it and go get some breakfast and read the paper.
Good luck..
Boy that s*cks not having access to 110, have they given you any other way to possibley get future stuff..
