Something (maybe lightening) caused me to loose my TV equipment. After troubleshooting discovered that I also lost Xfinity cable box. Replacement cable box works with another replacement HDMI
TV , but not with original LG TV on either HDMI input. TV powers up, but still intermittently responds to remote for a while, then quits and need to be unplugged to be reset. Also setup screen that shows selection for setup screen deterreates after a while by becoming unstable with jitter.
JA: Has this happened before? And have you tried unplugging your LG and leaving it off for a few hours?
JA: Does the TV menu work? Do you have the same problem on all sources/inputs?
Customer: Only tried the HDMI
JA: How long has this been an issue? What happened right before this popped up?
Customer: Never happened B4,
JA: Anything else you want the TV expert to know before I connect you?
Customer: I think lightening is a factor
