Vizio Tv Ir Sensor Replacement

Infrared issues aren t brand specific whether you ve got a sony a vizio or an lg tv remote sensor problems often boil down to a few common causes. We ve had a vizio tv for at least 10 yrs we had the same problems you have been having we also purchased a universal remote control and nothing seemed to work with the codes given we discovered it may be the ir sensor on the tv itself so i opened the back of the tv using a screw driver and the sensor on the right side of the tv was dirty. My tv is a vizio e3d420vx which is known to have problems with the remote and ir sensor going out.
