HDMI cautions.

In the past 2 months we have had 2 clients with very nice theatre systems complain that they had no picture. Our service calls revealed that the HDMI connection ports had been damaged by excessive voltage. Both of these clients have very good a/c power protection, so how did this happen? The power/surge protectors protect the equipment that is plugged into them, but do nothing to protect the electrical components from each other! We can’t point fingers, as these clients were using different service providers (Bell & Rogers), but we suspect that these over voltages came from these devices.

Unfortunately most power/surge devices do not protect your receiver from power spikes and surges that come in on the HDMI cabling. We are actively investigating this issue. There are a few listed online, but as yet we have not tested them. More to follow.
