Get an AM radio , turn it on , take the remote near to a radio ,
press a button on IR remote ,tune till you hear a sound ...
for a running remote it will give you some sound as button is pressed ..still the remote may fail to work as desired because it may emit very
less IR to trigger your equipment
main causes :
you have put some cover on remote
or
battery problem
or
IR diode gone bad
if no sound comes the oscillator might have gone bad /key pad got worn out /
battery problem..etc
