This is the Second strike in 2 years that did the same thing. The first time I thought it was a fluke but obviously HDMI doesn't have much tolerance for stray charges.
Are there any recievers that take this into account and protect devices connected to them or would I need something inline?
Unless the receiver was struct directly by lightning, I can't see how an outside surge would be caused by the HDMI line.
However, any line coming from outside of the house, which includes power, coax, telephone, cable, internet, satellite could produce a surge. This surge could then cause a power surge within the receiver or projector, then knocking out the HDMI board and the device.
It is also possible that while knocking out the HDMI board, the surge traveled the HDMI cable. If that did happen, I would expect to see some discoloration on or near the HDMI connector.
Even if the surge traveled the HDMI line, that's still a secondary event. More likely is that both devices took separate surges from the same event. In either case you would be better off making sure *every* outside line was surge protected since that would mitigate the source of the problem rather than a secondary effect. That's also one of the reasons that there aren't many HDMI surge protectors (or a component video surge protectors or a coax digital audio surge protectors) - that's not where the primary problem is. It's the lines from from outside that cause the problem.
However, if you really want an HDMI surge protector, a simple Google search found this:http://www.firefold.com/%2FFREE-SHIP...SA-P30864.aspx
I have no idea what this will do to a normal high speed HDMI signal. So, buyer beware and I'd make sure that this device isn't going to degrade the high speed signal before purchasing. Also, even if you purchase and install this device, I would still expect that at least one of the HDMI boards would fry if the exact same event happened again. Finally, not all surge protectors are created equal. Make sure you look at the ratings of each to find out how much energy the surge protector can dissipate.
