The first thing I would do is invest in a surge protector to avoid any problems like this in the future.
If you do end up buying one I would also suggest you ensure the 'Ground' light is lit up. Older homes (25+ years), don't usually have a ground on the electrical outlet.
I've seen many assume they were protected while never bothering to check whether the plug was actually grounded.
An electrical storm hit my area two nights ago and, while there were not direct hits and no power outages I seem to have lost two of my four HDMI ports on my SAMSUNG LCD TV. While I have adjusted and am using the two remaining good ports have the following questions - is this difficult and expensive to fix? Do I unplug my HDMI cables every time a storm hits? If needed, can I expand my remaining two ports with a hub? Any suggestions would be appreciated.
