I have been having Card issues since I got the S3 about a year ago, channels disappear, black screen, card error msgs etc.. I would have to reboot and reinsert cards1 at a time to get them back for a short period. I even got new cards a month ago which seemed to fix problem but came back again shortly after.
I remembered when I first got the install and a bad or weak Ground block made only 1 hd channel not come in.. I coulldnt believe it either but after it was changed .. it worked instantly.
So yesterday I again was missing a bunch of channels and even got a message Card 1 "not a viewing card" I did not reboot.. instead I ran new cable lines and changed all connectors. RG6 Quad & Compression Connectors were used. Then all worked perfect.
This must be really sensitive because my cables thought to be perfect before and even cablevision tested my signal at tivo and it was high. The cables were not old at all and there is only 1 split for a cable modem.
Where by now I would have had lost at least 1 channel...so Far all is perfect.
I will be finally relieved if this stupid simple fix made evrything work..! FINALLY!
Cant hurt for anyone else to try it... right
