No sound. I turned the TV on and there is no sound. I tried to change the sound modes on the menu but nothing helped. I noticed that you suggested to someone else to check the sound IC. I am assuming you mean integrated circuit...how is the average Jane supposed to know how to do that? This TV is a real piece. We have already had to have the power supply??? whatever replaced because it wouldn't turn on at all a couple of months after we got it. Please help!

no way to switch the sound off

Hello, It sounds like when you pressed the remote you inadvertently changed the scan on the ctv. This can cause the ctv ( colour tv ) to change from say ntsc to pal or similar. Even a reset button wouldnt help as it sounds like it is within the setup menu. You could try, as I have done this myself with a similar problem, disconnecting your dvd and putting it aside. Then, pressing the remote when in tv mode and watch for any change in screen flicker etc. If you have the original remote for ctv use that. If as you say, the tv goes to standby mode, you may have damaged the power supply, as the power supply will shut down to standby at any sign of a short.

first try new batteries and be sure you have pressed the AT&T mode button at the top left of the remote - if you still have issues then on the sharp tv menu - turn off any energy saver mode, Optical Picture Control, taking the picture mode from dynamic or vivid to standard, and if that doesn't work - try changing the backlight settings if your tv has one.

It sounds like you need to turn off the text mode in the closed captioning menu,

Honestly, that sounds like one of two things happened. Either the resolution of your computer video card changed or (I'm not sure with your specific TV) the TV's resolution changed.
If through the TV menus you can adjust PC resolution, I would try changing the resolutions. In the LG 47LB5DF TV, press Menu, then go to Picture, then go down to Screen. On the screen menu, you will see Resolution, Position, Size, Phase, and Reset. First try adjusting the Resolution to some of the options you see. If that doesn't work, try to reset the screen settings.
If adjusting those settings on your TV does not help, then you will have to change the resolution through the computer. Try connecting a monitor to the computer. If you get a picture through the monitor, on the desktop right click and select Properties. If using XP go to the setting tab, if using Vista/7, select Display Settings. Lower the resolution to something you think the TV will be able to handle, then connect the PC to the TV again. If you are using an HDMI connection to the TV, you may have to turn off the computer, connect the cable, then turn the computer back on with the TV on the correct input.
If the monitor doesn't show the picture or if you don't have another monitor, you can try adjusting the picture in safe mode, by pressing F8 after you press the power button, before you see the Windows loading screen. Press if multiple times if necessary. You should see a screen that gives you a few startup options. Select Safe Mode. After Windows boots up, you should still see the screen as the resolution would have been reduced. From there try changing your display settings.
Hopefully that info has helped. I noticed that you asked this question 2yrs ago, so I hope you have already figured out how to fix your problem. I simply wished to post this in case it would help you or anyone else had a similar problem. Good luck and take care.

cAN YOU TELL EXACTLY WHERE U CONNECTED AUDIO IN?

Look in your tv settings menu and see if the speakers are turned off there is an on/off setting in the menu..

wHEN YOU GET THE MENU UP YOU HAVE TO HOLD THE MENU BUTTON DOWN UNTIL THE MENU DISAPPEARS THEN ENTER 9876 ENTER. YOU CAN ALSO JUST AUTO PROGRAM THE SET AND IT WILL COME OUT OF SERVICE MODE.

Make sure connections are going-audio out from tv to d-tv/cbl in on back of reciever. Then turn on tv and turn reciever input to d-tv/cbl and make sure the input mode is on auto. Hope this helps you.

is there a switch on the back of the set?
