MY TV MODEL NS4200LE 3D Smart TV is working, remote also not functioning, while switch on showing launcher isn't responding like that
SOURCE: TV won't respond to remote(s)
I don't know of any adjustments for the IR receiver but the receiver itself could have gone bad or something may be blocking the IR lens not letting the IR signal get through. Maybe (but unusual) there may be a cold solder joint in the IR circuit. Sometimes dust will collect on the inside of the IR lens causing this problem. You can verify the operation of your remotes by holding them close to an AM radio receiver and pushing the buttons. You'll hear a popping sound through the radio speaker whenever a button is pushed. You may have to tune the radio up or down the band to pick up the remote's signal. Stargazer

We had this problem with a 28PW6515. The control would work for 30 seconds after switching on, then nothing. It was diagnosed as the "glue chip" which handles all the control functions. About £200 to fix it as it's a surface mount chip.
waynejman, I have the same exact problem, can you tell me what your outcome was?
