TV changes input and sound on its own

The TV will automatically change inputs and then the volume increases on its own to level 100. I can then change the input and volume manually from the TV, but after 10 minutes or so, it does the same thing all over again. Please help!!?

The only simple thing you can do is to check the manual buttons on the set for any sticking. When pressing a button down you can feel the detent.(click) When releasing the button it should raise up freely. Sometimes while cleaning the cabinet moisture gets on the switch assembly under the buttons causing random activity. I have experienced three common causes for your problem. 1 sticking buttons 2 defective switch assembly. The assembly can be unplugged from the circuit to see if the problem goes away. 3 a problem with the microprocessor that controls the functions.( requires a qualified tech to repair
) hope this helps

The audio output level is too low. How do i increase it? I have to turn the volume up on the TV almost maximum to hear a "normal" level of volume.

my experience says that the VCR/DVD recorder does NOT has a volume setting inside. Cables may be bad or connected to wrong input but most likely, the TV has a setting for the volume for any source and that is probably set to mid-range like on a PC sound control panel. Go the audio setup on the TV and see if you can adjust the level for each input.

Volume when on tuner is very different than when on DTV

Under the input menu, there is a volume trim function which allow you to increase or decrease the volume level of each input. It is designed so that the volume of different components can be matched to prevent a blast of sound when changing to a lounder output. You can increase the alevel of the dtv input, and decrease the level of the tuner. Tuner volumes are usually high.

Low audio through tv speakers

It sounds like a connection or signal level problem, your audio system may have a greater sensitivity than your TV, has the DVD got an output volume level to adjust, some do via their remote control also some TV's have independent volume levels for their inputs within menu settings.
Looks to be phono audio so if its none of the above then you will need a small audio pre-amplifier to increase the signal level, though for my thoughts this might produce a buzz problem because an amplifier might pick up stray noises from the TV or DVD.

Amazon or ebay may help there for small units, in a metal box is best for screening, it would not require a massive pre-amp with high gain, a battery type would need to be powered by AA types for long working periods if you go that route as a PP3 will fail over extended working time.

Hope this helps........

Sharp LC-42D43U troubleshooting with the maximum volume sound

Found this on another site and it worked, had to switch back and forth a few times but it worked........

I have a Sharp LC-46D43U LCD TV. I think this is a entry level for large lcd tv's. With the volume all the way up at 60, my wife and I could barley hear the tv. I was playing around in the menu and some how have the volume at almost twice the volume. What I did was:
Go into the menu
Go to option
Go to output select
and change from fixed to variable and back to fixed. You may have to do this a few times.
Sometimes the volume goes loud after 1 try and sometimes it may take 10 or 20 tries.
But if I change any settings, even the channel sometimes the sound goes back down to where it was.
Has anyone done this, did it work for you. I don't know very much about electronics and I have now ideal why this happens.
I wonder if this is just something with my tv.

I really don't know, because some of the newer gadgets come with fixed volume control due to law suits, ect. Try to see if you can bring you TV menu up and see what the sound setting is.
