Did your HDMI cable get jostled? You might try re-seating it [nt], posted on January 19, 2017 at 00:35:47

Several years ago I returned from out of town and found that I lost all four HDMI inputs to my Samsung 650 series 52" LCD panel. Neighbors told me there was a lightning hit nearby during a violent thunderstorm while I was away. I have AT&T U-verse and the storm also took out the Gateway controller/modem and the DVR.

After doing some research I discovered that HDMI boards are very sensitive to voltage variations especially in that model Samsung. I also found I had a loose ground wire where the signal cable enters my house.

The entire HDMI circuit board would need to be replaced at a significant cost. I never had the Samsung repaired and chose to use the component inputs until the panel was replaced a year ago with a Vizio M65-C1.

The loose ground has since been secured. I also added a ZeroSurge 2R20W-GDR Filter/Surge Protector.

Interesting. Worked for my LG TV too....., posted on January 20, 2017 at 13:08:04

Our LG TV in the guest bedroom was working 100% fine with the Comcast cable TV box over HDMI for nearly two years. It was plugged into HDMI Input-1.

I just purchased a Blu-ray player and AppleTV box for the guest bedroom and rerouted the HDMI cables through the drop-down AV drawer in the dresser just below the wall mounted TV. This required unplugging and replugging the HDMI cables.

The LG TV kept displaying "No Signal" on HDMI Input-1. The cable TV box was securely plugged into HDMI Input-1. I fought with this for a while but no luck.

I finally decided to power everything OFF for a few minutes then power it all back UP. It worked! Weird.
