When it rained really hard the other night it was noticeably worse.
You said you have an under ground electrical service.
Pad mount utility power transformer? Yes?
If yes,
Front of house or back of house?
By chance have you ever noticed a ground fiber electrical junction box just inside the property line? Sometimes they are flush with the ground and sometimes, often, the cover and part of the box will be above the ground a few inches. Usually the box will be somewhat centered on the property line of two property lots. Some times it might be on your property or the neighbor’s next door property. If you have such a box good chance your electrical service wires are jointed/terminated inside the box. If the connections are not water proof, which they usually are not, and the Lineman that made up the terminations didn’t keep them high in the box just below the bottom of the cover, then the terminations could have been laying in ground water from the heavy rain. Water will seek its’ own level.
I do have internet coming in over Coax wire and then have CATV going into my OPPO 105D but I’ve unplugged it and plugged it back in with now change. I don’t have cable, just internet, so only the OPPO is hooked up.
Unplugged? Do you mean you physically disconnected the CATV Cable Providers Coax cable "F" connector from what ever it connects to?
What kind of neighbors do you have around you? Neighbors that are/maybe fed from the same utility power transformer as you. Any of them running a business say out of their garage? How close are you to any commercial business from your home.
Did you ever contact the utility power company and talk to them about your problem?
