Troubleshoot tv remote

[Pdietz]

I have an RCA 32" LED tv. The remote has quit working. I have replaced the batteries to no avail. I have to turn on the tv with the power button. The sensor is not blocked. THe remote flashes but nothing happens. Do you have a solution?

Do other functions on the remote work (input selection for instance)? If so you might be able to clean the power button, Google for instructions how. May not work or work for long. Worth a try.
You can check if the remote is actually sending IR

If it is then the IR problem is in the TV.
Hope it's the remote since that is cheaper to replace,
