    I've blown three receivers in my condo unit so far the tells me there's an open ground somewhere in my electrical system. I've tested all my outlets with a tester they show that their fine. So how do I find the open ground.

    If you're just using a standard 3 light outlet tester it will only show you that there is a hot, nuetral and ground connected. It will not tell you voltage or if there is too much current, which is the cause of devices being damaged, so you'll need to get someone who has better equipment or start finding out where in the circuit the nuetral is becoming the hot (usually the main issue of this situation).

    Your symptoms tell me that you're in serious need of a UPS. A good one should all but eliminate power as the problem as well as alerting you to when whatever it is that it is happening happens.

    The most likely cause of electronic devices cooking is low voltage, not spikes or voltage coming in on the wrong leg.

    An open ground doesn't sound like the likely culprit in your situation, and if it's an intermittent problem, it will be hard to find even with the right tester. By "blown", what do you mean? What was the failure mode of your receiver in each of those three cases?

    Simplest cure, like others have mentioned, is a good UPS.
