I'm very sorry for any inconvenience this may have caused you. Unfortunately, these symptoms suggest that your TV will need servicing. Here's the thread where you can get details on setting up service: http://forums.cnet.com/7723-13973_102-542437/service-issues-click-here-for-help/
The touch screen mode on the tv panel to turn tv on or off, volume control, etc is not working -- completely off -- how do i turn it back on?
Also, the bottom of the tv screen there used to be a solid green line. Now the solid green line is appearing like red dash lines on the left of the screen and the rest remains green. What is happening?
This tv is less than 2 years old.
