Dick: Welcome to iRV2.com! I, too, wish it were under better circumstances.
has a good listing of replacement Intellitec boards, I'd give them a call if only the PC board is bad. This board
may be the replacement you need.
You should be able to inspect the system, removing breakers (with all power off, of course) to inspect the load center distribution panel to see if it needs replacement.
Replacing the PC board is relatively simple, but replacing the whole load center is not, lots of wiring to remove and replace.
Also keep in mind that the surge may have traveled to the display
and taken it out, too. Removing and inspecting it may not be a bad idea, too.
The only other active part of the center is the current sensor, if you need to replace that plus the display and the PC board you might be better off ordering one of these
, some cables are also be provided to replace any that were destroyed.
