Lightning damage w/ photos

I'd look for the receipt and call the manufacturer for any repair reimbursement or replacement necessary. Typ[ically all they need is some sort of documentation that the equipment failed diue to a spike, surge or strike from a repair facility or technician.
Although it doesn't make much if any differance for your dish equipment (since they probably covered it for free, it should cover the other items you mentioned such as your tv, avr, cat 5 hdmi extender adapters, etc.....

It only takes one of these experiences to teach folks a valuable lesson - lightning strikes can cause damage even when the happen miles away.
A couple of years ago, there was a home hit by lightning 5 miles away from us. One side affect was a major power fluctuation at multiple power substations, which ultimately fried hundreds of thousands of dollars worth of TV's sat and cable receivers, AVR's, and even garage door openers.
This was later confirmed by the power company. They indicated there was power-related damage reported by more than 600 customers from that single strike.
Fortunately, we have power protection on all our valuable electronics in the home, as well as the garage door openers. No damage here whatsoever.
(6) of our immediate neighbors alone had a total of 14 HDTVs, 4 AVR's, 5 sat/cable DVRs, and 3 garage door openers fried by the power surge created via the lightning strike 5 miles away.
It's terrible to hear about these cases each year...but hopefully they spawn people being more prepared for the future.

All homes should have an earth ground rod installed at the service entrance by the meter (Some old homes may not). Unfortunately, one rod isn't nearly sufficient to dissipate a nerby lightning stirike. This is very obvious by the damage to the rain gutter. Unfortunately, that's all that's required by code. Additionally. these ground rods are not subject to inspection and often become loose and corroded. Multiple ground rods, spaced apart the distance of their length would help greatly in dissipating the charge before it enters your house, where one rod would saturate and cause the surge to seek other avenues of disappation, such as the grounded rain gutter. Also, your first line of defense after the service ground rod(s) should be a quality whole house surge arrestor installed at the breaker panel and which protects all possible service entrance combinations. eg. Line to Line, Each Line to Neutral, etc.
If your dish itself was a victim of a close strike, it's an example of why the dish itself should have been directly earth grounded along with a ground block connector on the RG-6. If the dish has a ground rod(s) separate from the service rod(s), the two locations are required by code to be connected together by a minimum of #4 solid copper wire.. This allows the "Ground" network in and around your home to literally bounce up and back in a near uniform manner. It's not possible to prevent ground from rising above reference level during a lightning strike. But if the entire ground system in and around your home rises and falls simultaneously, minimal current will flow. No current flow, no damage. See "Single Point Ground" for more information. In addition to using this scheme at my home (I do so because I also have two large communication towers in my yard), I have my entire home theater, TV's, PC's, router, switches and DSL modem behind UPS units. This offers another line of defense. As a bonus, if power is suddenly lost, an orderly shutdown of the PC's will occur, and the DVR will remain up for a considerable period of time with no reboot required.
Finally, if your home is subject to a direct strike, all bets are off. Even the most well thought out protection scheme can fail in the event that happens.
