Clean plaster wall job done, but signal keeps breaking up

Just finished an install in an old brick building. Proud I didn't crack any plaster running the lines. Now the customer's TV picture gets fuzzy every few minutes. Think it might be interference from the existing wiring?

Wow, you didn't crack ANY plaster? In an old brick building? That's the real miracle here. That old plaster is like working with solid dust, it cracks if you look at it wrong. I usually end up with a dozen hairline fractures just thinking about running a cable. The signal problem feels like a smaller issue compared to that.

Jenny183's old wiring fix might work but how bad is the breakup really in an old place like that.

Could the old wiring be the issue, like john_lopez hinted at?

My electrician buddy worked in a 1950s building and had the same fuzzy signal issue. He found old, unshielded power lines running parallel to the coax were causing it. @john_lopez is right, the plaster survival is huge, but this might be a simple fix with some cable separation.
