To dignose if your remote control is faulty just point your digital camera towards your remote and push the buttons.
If your remote works you should see light flashing on the LCD view finder of your camera.

Repairing the remotes can be succesful about 90% of the time unless the remote has been chewed by the family dog ?

Make sure your xbox is set to plain TV instead of HDTV. There is a switch on the cord that plugs directly into the back of the xbox.

SAID THE PROBLEM MAYBE

You need the original remote controller to be able to switch input modes.Universal ones don't work. If you don't have the original remote and can't find it ever then the only way to reach your tv is through coaxial antenna port. So you can buy an rf modulator ( very cheap) and connect your red yellow and white cables (rca cables from a dvd, game console etc) to the modulator then connect the modulator to your antenna with a coax cable. This worked for me. It placed the connection to channel 4 and other channels are still working,

You can buy the RF Modulator from: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=180299245670

the tv should be in video mode in order to accept input from dvd...when it does'nt work try to use a modulator that should be connected at the back through using cable with f-connector both sides...

this can happen with the flyback transformer's brightness which can be adjusted , also the power transformer can make humming or buzzing sounds which can't be adjusted , also this can happen with the picture tube or the CRT board failing , and sometimes chips with heat sinks or the IC's themselfs

Go to Radio Shack and get an universal remote control, i have a Phillips Universal to change mine. it has a "input" button that also says tv/vcr that will let you change channels to do this.

Most TVs have a choice of air or cable in the menu portion of the tv. press menu go to setup and from there you should see an option that says air/antenna or cable. You will have to either toggle to get the air selection or highlight it. Then you should be able to get to channels you need.

An easier solution may be to go to the Dish receiver that controls the image on the tv you can't get to 73. With tv and satellite on (make sure both green and blue lights are on) press on your Dish remote #1 with the green tab on the bottom the following sequence: MENU - 6-1-5. tHIS WILL TAKE YOU TO THE MODULATOR SET UP PAGE. Move the highlight from cancel to the mode section an highlight AIR and press select. Then move the highlight back to the right to DONE and press select. Press cancel three times or view live tv. then go to the other tv and put it on ch 60.
Hope this assists you.

may be the problem is the how you connect the converter to the tv... it shoud be connected at the video in and audio in of the tv... and the cable wire should be plug in the Rf in of the converter.. you can scan all the channel thru the remote..

check your tv if the timer is on..if the timer is on,off it..

you can get the code by manual searching of the code... see the direction at the remote to find the code...there will be a button to be push in order to search the right code..

thru manual search and lock the channel one by one at the memory...

I have the opposite problem. I don't have the remote, it broke, and I'm stuck on channels when I want to play a game. How do I fix that without the remote?!

i just got mine to work i had the same problem, i bought a universal remote, make sure your dvd player or whatever his hooked in, and hit the input button on the remote, it worked for me. I couldnt get anywhere by looking through menu, but i just hit the input button and it magically appeard :)
