I got a Wii for my birthday - yah! My remote stopped working ages ago but I didn't worry to much about it. Now I need to be able to change the input in order to play with the Wii. I ordered a new remote which also didn't work and figured it was a problem with the sensor - I see from here that this is a common problem!!! (not impressed with that!)
So can I change the input manually somehow or do I have to buy a new TV??

Check the remote control for its infra-red emission. Check it with fresh batteries. Check by pressing all the buttons on it; and see whether all of it generates infrared signal while pressing. If it is found OK, check and replace the infrared sensor inside the TV. If you wish to get some details; check the site linked here. It has details about how to check a remote control; by one among the post. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ If the remote control is found OK; check and replace the infra-red sensor inside the TV. Contact any service technician.
There is some problem in semi conductor install inside TV from where it catch signals from remote, detect frequency and change and adjust your desire frequency and then your fav channel comes on screen
get it repaired only that part which receive signals from remote

That's a problem with universal remote controls. Often they don't control every function of the TV. They just don't have the buttons needed to control everything the original remote did. You'll have the most basic controls - power, channel and volume up and down - and maybe a menu button. But you'll frequently find other things don't work, like switching inputs. There isn't anything you can do except try all the codes for your TV brand and see what each button does. You might find that the buttons have different functions depending on which code you've entered. You might also look for another brand of universal remote that has more functions available.
If the remote sensor cover is missing on the TV, the remote would still work but you may get other effects like the TV changing channels on it own. This is due to stray infra red signals. If it's not working at all I would suspect the remote control handset. You can test it by pointing it at a digital camera lens and watching the display screen on the camera. You should see white light comming from the remote when you press any of the buttons if it's working. Digital cameras can see infrared.
Test your remote by placing it in front of a video camera or web cam if you have one.. Press the buttons and watch the cam to see if you see the light coming from the remote.. The camera lens merely slows the light to a visable spectrum.. If no light your remote is not working... If light replace the sensor in the TV..
You could have a defective IR sensor in the tv set that sends the infared signal to the MIcroprocessor IC. These are something you cant just replace, as it needs to be trouble shot with a scope to see if theres a data signal comming out of the sensor and if there is it could be a bad solder connection somewhere between the sensor plug to the Main IC. Also could be the B+ that supplys voltage to the sensor. Unless you have had electronic repoair experience, You should have a pro assist you with this repair. Sorry I couldnt assist you more with this . Good Luck
