No, that's not a broadcasting issue. That error means that something is wrong with your Single Wire Multiswitch dish equipment. Most likely it's a loose or corroded coax connection at your dish or ground block. Or perhaps a defective dish LNB that's become temperature sensitive. Some of those things you can check yourself, but a service call will fix it for sure.
As a tech, EVERY time I see this on a service call I do 2 things.
Replace the cable from the dish to the groundblock, then move the power supply before the splitter if possible, if I cannot do that I change all cabling in between the dish and the power supply, even it is does not look or test bad.
99% of the time it is a power supply issue, almost never the power supply itself, but inferior cabling from the dish to the power supply.
Do not accept the reset power supply and receiver recommendation from a customer service rep, this is not a fix...
You will need a tech there to check the cabling I mentioned. 775 errors DO NOT fix themselves, there is a valid issue with the system...
