This was a trouble call i responded too for missing channels and no OnDemand. Looks like PG&E is having a grounding problem at this house and is using Comcast Cable as a ground.
I work for Shaw and had this happen when Telus connected to our lines though their ADSL boxes. It fed back on the drop and would spark at the tap. Lucky I didn't get that bad of a shock when I disconnected them.
It happens. Worst I had seen was an entire neighborhood with a bad PECO ground, voltage feeding back into the Comcast taps. Entire drops fried, but cable was the least of those people's problems.
Thats not comcast cable that is causing that. Its something in the house that is not properly grounded. It is backfeeding to our splitter and even back to our ground block when connected. Its usually caused by an old TV or VCR or some kind of old accessory.
Similar shit happens with LNB power from a DVB satellite receiver hooked into CATV

Perhaps it's just power from the tap to the NIU?

When that happens you need to call the electric company because the power is using cable as their ground

looks like the neutral is broken, and hydro is using us (cable) as a return path. Seen it alot.. OR a bad piece of cx equip.
