A couple of weeks ago the light pole outside our house got struck with lightning and we lost power for a long time (really only 3 days). but ever since then my HDMI port on the back of my tv and XBOX 360 doesn't work (HDMI 3rd Port on LG TV) I've tried different cables and ports on multiple tvs but it still wont work but the xbox will work with the old av cable but I hate the low resolution with the cable. Can anyone help me?
