Cable TV receiver induced hum into system

I've read the prior threads which speak about direct pc dish based systems having hum when a ground is screwed up or one omitted. I'm having a similar problem with my cable tv receiver into my BAT S300X integrated amp.

I've tried grounding the box to the amp. It cuts down the hum, but doesn't eliminate it. All the electronics have been tried running through a PS AUDIO 600 or into the same outlet or into separate dedicated outlets.

No change in results.

What am I missing?

I'm having my youngest son do the test today.

I'll know soon.

Thanks again.

Audio Advisor sells the Mondial Magic's. If you find that you need one, look under "Manufacturers" on their website for Mondial and you will find an isolation transformer and an isolation transformer/splitter. I used the transformer/splitter and sent one output to my HT, and the other went to every other TV in my house (using less expensive splitters as needed). Hope this helps.

All Reponses here are just band aids...Your cable is not grounded to code-have them fix it. If it is not grounded with a ground block to the same ground that you ac breaker box is grounded to them you have a ground potential-basically a giant 9 volt battery that is looking for ground in between your components-HAVE YOUR CABLE COMPANY FIX IT!!!They are governed by law to do so....
