Re: automatic channel changing

We had the exact same thing happening with our same TV. We tried many things to fix it ourselves, but nothing worked. We finally broke down and took it to a repair shop. They were able to fix it within 24 hours and for $75. It has something to do with a short behind the input jacks on the front of the televsion. Hope that helps

How do we scan/program in local tv channels. We bought an external antenna, but get no picture. Typically, there is a protocol for scanning channels into the set. Model is Sansui TVS2746B, and the set was...

Okay, does this tv have a built in DIGITAL tuner? Most tv's only have an analog tuner. You can tell the difference while you are changing the channels. If the channel indicates 2.1 or 2.2 and so forth, it is on a digital channel mode. If you change the channel and it indicated 2, 3, 4, etc. it is analog. If it has digital capability change the input until you see 2.1, 3.4 etc. If you cycle through all the inputs on the tv like, input 1 (TV) input 2(DVD) input 3(HDMI) and so forth and you never see the digital channel you most likely do not have a digital tuner. You will need to purchase a digital converter which will convert it to analog and you can watch it by placing you tv on analog channel 3 just like the old vcr's. Hope this helps and please don't forget to rate this solution.

Cant change channels?

What is your antenna source? Cable or antenna? Try keying in a certain channel on your remote. see if you get that channel. Tv will not auto program if you do not have channel source coming in to antenna input.

Need an Input to hook up Dish network/xbox 360

Sometimes its tricky with those buttons on the front but with most tv's you can get to the menu and change inputs.
One you figure that out you will want to go back in and add that input as a channel in the add/remove channel section then you will be able to get to that input by just changing the channel down below 2
( another way to do this would be to run the auto program with the devices on and see if it adds them that way)

Can't change our Panasonic TV channel to watch DVD input

Buy a 21 way scart.This will have an 'AV' enable connection built in. After fitting, turn on the TV, then turn on the DVD player. It will automatically enable the DVD through the scart socket.

No channels?

Try going into the setup menu and make sure the ANT input is set to cable. Then look for Auto Program or Channel Setup and let it scan and find all the channels it can receive. After it's done you should be able to go up and down through the channels.

Sharp tv changing channels

Well, the only thing that seems to be working so far is to plug AV cables into the "input 2" ports (on the front of TV). I plugged in my PS2, without turning it on. It has not switched at random since (about 30 minutes - it had been switching off and on for the past 2 hours). Anyone else have similar success?
