Changing changes without notice

I just received this TV. the TV changes channels on it's own. kind of like if your sitting on the remote (but of course we're not). does anyone know if this is an easy fix or something I need to take to a shop to fix.

The easiest thing to check is if the channel up or down buttons are not pushed in too far forcing the switch to make contact all the time,the other possible reason is some of the cleaning solution or water might have gone down to the buttons and creating a short making the switch active all the time.For this reason you will need the help of a servicer to find you the parts and replace them.Let Us know if you need more information.

My remote wont work called about 3 weeks ago for replacementno response... and my tv is changing channels on its own,


You have to get nasty with the manufacturer at times to get what you want. No reason a remote can't be replaced in a few days; however, the problem seems to be the TV itself. If the remote is not active, and you experience channel changes automatically, it may be the TV receiver section alone. Call the company and mention that without the remote energized you have channel changes, they can run you through diagnostics to find the problem.

I cant figure out how to change the channel to input/video on my broadband tv without a remote


This problem may be more complex than just the selection of a channel to receive video. The first problem is what channel to receive the video. Usually its received on channel 3 or 4. You select that on the video output and match it on the TV. That assumes your recorder is attached via the RF (antenna) connection. If its hooked up via the component connect then you must have a remote to select IN1 or IN2 on the TV to receive video. Remote controls are available on line. Do a search on your TV model and remote control.

This problem never happened before , We on the tv and the channels keep changing by it self . We are not touching any buttons and we even tried offing the tv and switching the power off . Each time we on...


As a test, block its (or the cable Box's) remote infrared sensor so even you can't change the channels with a remote. Then watch and wait. If it keeps happening, you have a poltergeist or a defective unit.

If not, something out 'there' is emitting infrared signals that the unit interprets as channel commands. Find the remote someone is sitting on or that guy across the street who's aiming at your TV with HIS remote.

Need intructions how to program remote control on vip722k second receiver


Press and hold down the SETUP button located on the remote. Wait until the INDICATOR light turns on. It will blink once the button is pushed, however once you see the indicator light stay one, release the button. Click the button to the DEVICE you wish to program. If it is a TV, then click the TV button. If it is the cable box, then click CBL button. After doing so, the indicator should still stay on. Press the DOWN CHANNEL button several times until you see the RECEIVER yo wish to program respond. Example: If it is a TV, then you will notice the CHANNEL change once the remote locates the correct settings for that receiver. If you see the receiver respond and you are pushing the down channel button but nothing is working, it means you passed the internal settings of the remote to the receiver. Try pushing the CHANNEL UP button slowly. It may be able to relocate the the proper settings. Once you see the channel change again, press ENTER to program the remote. If this fails, retry the same steps. In some cases you may miss the correct internal settings.

My remote wont change channels


I need to use the cable remote to change the channel and the TV remote to change volume.
That is because your TV is looking at the output of the cable box (probably on channel 3 or 4) so the TV has to be statically tuned to see the cable box's output.
On the second question; I, and perhaps others, can't answer this without spending a lot of time to download manuals for both systems while you have them (presumably, since they are new) on hand. You didn't include the TV's model number anyhow so even that wouldn't be adequate.
The home theatre may have a receiver but what does it receive? Unless it also has channel capabilities that correspond to cable channels, it can't. The typical routing should be from the cable box to the TV S-video input and the sound can be routed separately from the cable box to either/or both, the home theatre's and also the TV's audio inputs.
When I am installing new stuff, I make a sketch of the routing I want (or have) to use. To me, this is less confusing than the supplied instructions.

MY REMOTE WILL NOT CHANGE CHANNELS ONLY TURNS TV ON OR OFF


After much trial and error, we discovered a temporary fix. We taped a 3 x 5 index card to the front of the box directly to the right of the time/ channel number. The remote will change both the channels and the sound level with this "fix." Could there be some kind of emission coming from the box that interferes with the remote? Maybe Motorola could put a more opaque front on the box.
