Hiya, Ever since hooking up my PS3 I've had a problem with a ground loop thanks to it having a grounded power plug and my digital cable box going to the TV. Now, I can't move to a different outlet as I've tried that and I'm in an apartment. Now I know I can get a surge supressor/protector with Coax support for the cable box and that should resolve it, however I already have more surge protectors than I need. I will do that if I have to, but my question is that if I buy some really good heavily shielded AV cables for the cable box, will that be enough to shield the TV from the ground loop?

Upgraded cables will not remove a ground loop. What you need to do is go to Radio Shack and buy a "ground loop isolator". They're inexpensive and work wonders.

It is called an Isolation Transformer. It does not solve the problem, which is that your cable is not properly grounded, but it will stop the hum. You should call the cable company and tell them that this is happening and they should fix it (at the incoming box). A surge suppressor with coax will not solve this.
