SOURCE: Sony TV power and volume not working

Since remote does not work, try taking out batt and turning on by set. See if still turns up. It could be that the up button is jammed inside set. Does everything else works? See if you can go to menu and turn speakers off, this will allow you to work on set and not worry about noise.

SOURCE: mintex 37 inch wide screen. remote is working however cannot change channel, input source or volum. only turns tv off. The buttone on tv doesnot work connot change input source or volume

Check if the remote is in TV position, that is, because most of the remote controllers have the feature that you can program them for use with another devices. Make shure that one button that says "TV" in pressed and released once before you try to change any function on the TV.

That, I would guess, is a decoupling problem in the decoding section of the audio stage, or a poor connection in the audio section. Unfortunately a service manual and engineer will be required to find the problem
Hope that helps.

Very little volume, not very loud at highest


On the TV-use your finger to adjust the volume level, about midway, then use the remote to shut off the tv, then turn on tv with remote. Volume level should be better! If still not loud enough...using your finger on the tv...turn up volume & repeat remote steps.

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.

You need to change the Audio / Control Head, as well as the Pinch Roller of the machine. A worn out Audio cum Control Head will reflect in poor tracking and so will cause the above problems.
