[QUOTE="Terryl, post: 1084158, member: 369937"] Wait till the problem occurs, leave the receivers on, (I assume there are no switches in-line) then using a DVM check the DC voltage at the LNB connectors, (center conductor to outside of the connector) you should have ether +13 volts or +18 volts plus or minus a volt, anything less on one or both feeds then it could be a problem with the coax, or the receiver on that line could have a problem, the same voltage should be present at the "F" connector on the receivers LNB input. Water getting into the coax between the shield and center conductor can cause strange problems like this, and it doesn't have to always be the connector, a coax staple or nail into the coaxes PVC jacket can cause a headache like this.
