Sharp tv changing channels

Our tv changes from the channel its on to the input channel by itself. Sometimes just keeps switching back and forth or just stays on input 2. What is the problem? the tv is about 4 yrs old. Anyone else experience this problem? What will we need to do to fix this? or, is the tv shot??

    I have the same problem! My Sharp TV (about 3 years old) just keeps switching to input 2 and then back to TV mode. It will do this randomly. Can someone please help?

    I have the same problem. My TV is a Sharp 32F641. The channel keeps changing to Input 2. PLEASE HELP!!!!!!!!!

    I have the same problem... I am exploring three options:
    1. I have a tivo - maybe there is some interference there
    2. I have audio video cables coming out of the back of the TV that are not connected to a device. I am going to try disconeecting them
    3. something in my house might be sending a signal to the remote port to switch the input (but I seriously doubt this).
    Does any one else have similar circumstances?

    Ours is doing the same thing as well. It gets pretty annoying.

    Same problem on 4 year old TV that just started and became worse quickly.

  • jmicheli May 13, 2009

    Same situation, doesn't happen all the time. Maybe at midnight, 6am, all different times and may not happen for a week. At first I thought someone had a similar remote nearby. Have any of you got a response to this or got any word from sharp?

I put the plugs into the Input 2 for my SNES and it works now. That seems to be the solution. The TV also made a faint clicking sound.

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?

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.

The tv switches to Input while trying to watch Dish.

Likely a button on TV is sticking down or partially shorted.

Channels and inputs change by themselves

sometimes unplugging it from the wall for a few minutes or even overnight can fix weird issues like this.

also, there is a small chance that a new channel scan thru the menu system might refresh the channel memory and clear it up.

this series of TV's are prone to a lot of problems tho, so it will likely soon be time to start shopping around.

Channel keeps changing to 'Input 2' even when playing DVD

Have you taken the remote control out of the room? Try changing inputs from the TV.

Tv turns on and off by itself

Picture tubes rarely go bad. You have a bad connection or something on the circuit board that is breaking down due to the temperature change . Probably an easy fix. Not something an unqualified person can do though. Your local shop should fix this for about $60-100.
