The TV does not respond to the channel changer. changed to a new changer and batteries but did not correct.

Check the contact of the batteries in the remote "TV changer" by removing the battery cover and rotating or jiggling the batteries a little, to improve their electrical contact. If that doesn't work, try replacing the batteries. Finally, if the "TV changer" is capable of controlling more than one device, for example a DVD player or satellite TV box , make sure you set any switch that selects which device it controls to "TV".

Is it the tv's remote? Change the batteries
are you on a cable box? You need to use the providers channel changer. Tv is made to stay on one channel like channel 3 and the cable box runs the different channels.

Open it, rub its circuit and buttons from inside softly with spirit swab or piece of cloth wet with small quantity of petrol.

Go through the BOSE manual to see if another channel can be chosen to control the system. If not, try and locate them farther apart and shield the remote with your hand to avoid signal from getting to the unwanted device.

Well I just did this last night.
Its funny how everybody forgets to explain the basic tehnical stuff like setup and channel scaning.

We did not get any channels at first. but because I read internet a lot before on the subject, I knew that I had to do "channel scan".

ok first go to setup.. you have things on your tv changer or .. on the tv itself on the side back of it.
We have a new tv. Flat tv. if yuou have an old one you might have to get the digital exchanger thing that somebody mentioned previously.

If you do have flat newer tv..
first set up the tv to respond to antenna.
as the source.

then.. I had something that said.. digital off , and also antenna off. I had to change that to .. whatever other choice came up first.. and there were a lot of choices, like cc1 cc2 t1 t2 and so on.
I changed it to c1 or cc1 something like that.. on analog. that got us few channels. then I changed the digital one also to something.

I still have to tinker with it.. but we had only few channels and they are clear.

Hi
It seems that your TV's memory IC has damged. If this IC got damged, no fromt panel or remote signals will work. It is a small IC . It can be found very near to channel selector main IC [System control]. It is very cheap to buy. But replacing it is a skilled work. You have to contact any experienced service technician to get it replaced. This IC controls most of the functions in the Tv. OK.

A working TV remote is a security blanket that allows us the peace of mind of knowing that we don't have to get up unless nature calls or the house catches on fire. People are more likely to spend more time and energy to fix their TV remote than to get up and change the channel. There are a number of simple fixes that can ease your mind when your TV remote is not working.

• New Batteries

1. Check the batteries. Make sure the batteries are in correctly and, if they are, replace the batteries. If the batteries are dead or are not in correctly, your remote will not respond and the LED light will not illuminate when a button is pressed. Make sure the TV is plugged in. An unplugged TV will not respond to any remote.
   
2. Check the selected input to make sure the remote is set on the TV and not some other device programmed into the remote, such as your DVD player, VCR, or video game console.
   
3. Reprogram the sync code. If you are using a universal remote, it may have deprogrammed, leaving the remote and TV out of sync.
   
4. Unplug the TV for a few minutes. During a power surge, a TV can become "confused." Unplugging it for a few minutes will give the TV the break it needs to sort everything out and work properly with your remote.
   
5. Use another remote on the TV. Program a universal remote to work with the TV. If the TV does not respond, the problem is likely with the TV and not the remote control.
   

Channel changer from the remote? or from the TV? if it is from the remote, that's an easy fix, take off the batteries open the back of the remote, clean the circute board the one that is painted green, clean the remote contact pads as well the one that has a black dot like thingy with cotton balls slightly damp in rubbing alcohol, let it dry put it back together and replace with a new battery.

i put an extende piece of cable on my antena for second set raised it to same hieght as my tv in rear so ya dont see works great now

I was told that in order to view 2 different channels at the same time u have to subscribe to SKYCable and use the digital input instead of the antenna input and the antenna input you will have to use the regular antenna since there is only one tuner in the TV
