Has the same item broken down more than once? Let's say your console has a Panasonic BT-LH1700W (as an example). Has this BT-LH1700W broken down, been repaired, and then broken down again? If so, either the design (or the repair work) is flawed, or it is taking some sort of electrical surge/spike, or an environmental factor (heat) is causing the failure. If it is always a different item that is breaking down, then either its solely environmental or electrical. You may want to check what the incoming voltage is. Perhaps its so high (or low) that a voltage regulator is in order? You may also need more adequate surge protection. Just because a surge protector provides electricity to all of its outlets does not mean it is going to absorb a surge.
There is equipment in our machine room that is on all the time. It's protected by APC, TrippLite, and Furman conditioners (depending on the item). The only items I would be leery of leaving on all the time are monitors (burn-in) and amplifiers (heat).
