Try a new remote? I did run into folk searching for an exact issue match but didn't swap the remote. Never heard if they were open to try that. I think they were looking for another answer.
PS. Always put in new batteries.
I have searched the whole internet and cannot seem to find anyone with the exact issue.
This problem is intermittent. The remote control stops working. Remote itself is fine.
The standby LED goes out completely. It does not blink just off completely. TV works perfectly from the buttons. After a few hours the standby light returns and all functions properly with remote control. At a complete loss? I thought the remote receiver, but then it could be something else. Anyone experienced similar?
