All 4 HDMI connections not working
I have had the 42F430S for many years. Last night when I came home and found out there is a power outage during the day. Then I also recognized none of the HDMI connection works anymore, I mean all 4 HDMI connections which I had connected to different source (DVD, cable box, DVR, Roku) which had all works before. I had unplug the power to reset the TV. I had press the power button for 10+ seconds to do a reset. I had turned off the Autosource. I unplug all the HDMI cables and plug it back it. I tried each HDMI source and all of them go through the "Detecting" and then said "No Input Signal".
At first I thought the TV is totally broken but then I tried other input source for my Xbox and Wii which are not using HDMI connections. Both cases work so the TV is still functioning.
To me the problem is only with my HDMI connections (all 4). So any suggestion on what I can do.
Or it is a time to buy a new TV?
Thanks a lot for your help.
