Over the last 3 months our 721 has been locking up 2-3 times per week. A smartcard reboot seemed to fix the problem temporarily. Yesterday it was taking 5-10 minutes to change channels on the 721. I tried a power plug reboot. Since then the 721 hangs on "acquiring satellite signal". The DVR functions work fine. Check switch, signal strength, everything else checks out. Getting 90-95 signal on both 110 & 119. My 622 and 510 hooked to the same switch (DPP44) work fine.
I tried resetting factory defaults on the 721. Didn't work. Disconnected the satellite feeds and the rebooted with check switch to clear matrix. Reconnected feeds then did a check switch. Everything OK. Now it is hung on downloading the program guide. If I cancel out it gets hung on "acquiring satellite signal" .
Had advanced tech support on the line, for about 45 minutes. We tried most of what I had already done. Their verdict is that one or both of the tuners are dead.
So what does everyone else think? Dead? I'm thinking about leasing a 2nd 622 to replace the 721.
