HDMI Ports Bad?

[rhym1n]

I am having some weird issues with my Insignia HDTV:

• 
  DVD player works on port 1 & 3
  Chromecast only works on port 1
  The HDMI port on my Charter cable box doesn't work on any port or on 2 different working TVs

This happened all of a sudden. Is it possible that a storm caused some of the HDMI ports to fail? If so, how do you explain how some devices work in certain ports?

Since the cable box doesn't work through HDMI at all that is a separate issue. Charter should just replace the box.
A storm can cause HDMI inputs to fry since there is 5 volts on each and they can be overloaded. The surge coming through the cable box mIght only affect some inputs and not others. Try www.shopjimmy.com for a new input board for your TV.
