Unable to solve possible electrical issue
30 days ago, i purchased a 120hz flat screen TV for my master bedroom of a 30 year old condo. Everything was working fine until two days ago. The TV remote started not responding. I changed batteries, still didn't respond. I took the TV to another bedroom and TV responded to remote. Put a different flat screen TV in the bedroom and it didn't respond. I've led to believe that the electrical wiring in the condo is failing and cause electrical interference in the bedroom. Can anyone help me?
