SOURCE: TV CHANGES CHANNELS (BY ITSELF)

is this tv the same model/brand? far be it from me to claim poltergeists are at work, but who knows... the very first thing i would do in diagnosing this issue is to grab some electrical tape and aluminum foil, tape a patch over the ir receiver for the remote, this should be a shiny piece of black plastic somewhere on the front of the tv, some are marked, some are not.. if you have it, aluminum duct tape works great for this purpose.

to me, it seems like someone is messing with you using a remote, tv-b-gone, or similar product like a keychain universal remote.. if the tape over the ir sensor fixes the issue, i would look at roommates, kids, neighbors, or possible interference from other ir or light sources..

possible culprits would be:
universal remotes
dirty remotes that keep sending a signal with nobody using it
laptops or cellphones with an irda port
palm devices such as palm, clie, etc that have irda
intermittent strobes (emergency vehicles, bad ballast in a light fixture, etc)

i can't guarantee this is your problem, but it seems like it since this is your second tv with the same or similar problem... as a sidenote, the sony clie came with a universal remote program, i caused much chaos in my local video stores by shutting down their video wall while browsing.

SOURCE: ViewSonic N2750w 27 in Volume turns down by itself

Could be a problem with the down volume button on the tv. the board it's on ir its harness. Check them all. Make sure the volume buttons plastic actuator moves freely and is not stuck.

If these parts are all good, you have a problem on the main board. You may have to trace the control lines as far as you can and check any capacitors along the way. If you have an oscilliscope you can test the lines to see if the up volume is working correctly. If there is noise on it, you might find a bad capacitor if you can trace it back far enough. Schematic helps here.

Of course, make sure nothing is shining on the sensor window on the TV. You might want to scope that line as well (IR sensor line).

If none of that helps, get hold of Viewsonic and find your closest service provider. You can order a main board from them.

Of course, you could try just using the audio out jacks to an amplifier or a surround sound amplifer. Then you would use the remotecontrol for the surround sound system to control your volume.
Bet you were going to buy one anyway right?

While you have sound, take a flashlight and shine it on the screen, look very close and see if you can see a dark video image.
Let me know what you see.

SOURCE: i cant receive freeveiw channels

I don't know what make of TV you have but some manufacturers have two tuners at the rear of the TV. One for terrestrial signal & one for digital signal. If this is the case put the aerial into the digital input & try retuning. If this does not work then if you could provide the details of you TV eg. make & model, then I will try to help you further.

MENU SCREEN POPS UP, TV CHANGES CHANNELS, TURNS SOUND DOWN


Yes. Its probably a stuck button on the TV's front panel. Try pushing or wiggling each button on the panel. It could be the channel up/down buttons or volume up/down, menu, etc.

When there is a button that is making slight contact, it keeps the microprocessor busy attending to the command its erroneously receiving from the offending button and may not allow other functions to work when this occurs.

It doesn't matter which button is stuck, any of the symptoms you describe can happen.

Tv wont stop changing channels


ok, Sony had this issue on their early production. The problem you are having is called a leaky switch. The volume down switch on the TV is leaky. To fix this you must replace the switch. This part is called the switch block. Part number 1-473-549-21

Average cost $26
