I have a Sony TV and purchased a RCA remote control new from Walmart (as a replacement for a Sony remote control). The RCA worked fine for 2 months until I accidentally hit the wrong button. The little red light flashes on and off at the problem, showing I have current but no reaction at the TV. The old Sony remote control works fine (part of the buttons don't work), showing that the problem lies in the RCA remote control.
