It seems that the set itself changes inputs. Place it remote control away from the vicinity of the tV. and check. If it does the same, do a hard reset next. To make it a hard reset, unplug the TV from AC mains wall socket, and replug it back after 10 minutes or so. If these do not help you, be sure that the main system control memory IC to it is faulty and should be replaced.
Try to push the TV button that is lit red at top middle of remote for 5 seconds in stead of hitting input. In other words by holding the tv button down it might trigger it to respond better. Thanks Mike
NOTE THE COMMENT ABOUT THE RESET AND THE SIMULTANEOUS SELECTION OF THE + - SET and CLEAR BUTTONS to effect a reset after replacingg batteries
HOW TO INSTALL BATTERIES Remove the lid in the rear part of the remote control unit. Insert two AAA alkaline batteries of 1,5 V-DC. Make sure the batteries point in the direction marked in the battery compartment. The batteries last about six months. Depending on how much you use the remote control unit. Remove the batteries if you do not use the remote control unit for more than one month. Press the +, -, SET and CLEAR buttons together after batteries replacement. (This operation allows you to reset correctly all the programs. The remote control unit is to be set up again).Replace the batteries when the remote control unit lamp fails to light, or when the air conditioner does not receive the remote control unit signals. The batteries of the remote control contain polluted substances exhausted batteries must be disposed according to the laws in force.

Have the remote tested either with a tester that most shops have or in a dark room with a digital camera the display will faintly flash when remote pointed at it and buttons pressed.
Also if button does not work (power) unplug the set for a while to see if it will reset. If the tester shows same problem--no working for power or have to press ******* buttons 99% chance something got spilled onto remote and got inside
If set turns on with the power button on set the remote is : not set to TV, not programmed for the set, has bad batteries or is bad.
If it even works one function it may need to be reprogrammed or taken apart to see if works---you can test the remote by pointing it at a digital camera with a LCD screen and pressing buttons to see if it makes the screen flash on the camera.
Hello There is a infrared light sensor inside the TV which detects the infrared rays emitted from the remote control, when we press each button on the remote control. If this sensor has got damaged, the set won't respond to any remote control handset. The sensor can be located just behind the infrared sensor window at the front panel of the TV. To access it, you have to open the TV. It is a three terminal component, will be soldered diretily to front panel circuit board, of with the main baord itslef. Will look somewhat brownish black in colour. There are so many types can be seen . Just look what type if fitted with your TV. See some models infrared sensors. Check out which type your TV has.
