How to replace an ir sensor on your tv.
													
																	Vizio tv ir sensor replacement. 
									
	
		
	
																	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. 
																	Here s an easy wa. 
																	My tv is a vizio e3d420vx which is known to have problems with the remote and ir sensor going out.
