Click here to view full specs.[/qanda]we have had this tv for about 1 year we bought it second hand and it was working real fine but a couple months went by and the sound went away we went to plug in the ps3 today and now the tv dont do anything not even our cable works we cant watch tv and it dont show any picture or produce sound we can go to the menus and thats all but nothing we can do what do we do now?

First, try resetting the sound & video (if you haven’t already done this), i.e. go into the menu, select “Reset” and press the right arrow key.

If you haven’t already looked at the troubleshooting steps in your manual, this is worth a check as it lists a range of possible reasons and things to try if the sound or picture stops working. The troubleshooting section is on page 80 and the manual can be downloaded here.

As you can get into the menus, this means that its lamp (the bulb which projects the picture) is still good.
