The red light turns on but no picture comes on


Get real close to screen and maybe use a flash light to shine on the screen and see if you can see the picture still, it will be dark and almost not visible but you should notice something move. If your screen has picture then you most likely have a back light problem. Most common problems are bad inverters, or the inverter controller card. possibly a bad power supply but most likely inverters, test each circuit, replace as needed.

Lg 3000 42in tv, no picture just blank screen but sound is working


Sounds like a problem with your backlights. Could be the inverter, the CCFL's, the power supply board, or even the main board causing it.
But don't fret, this could be a very good opportunity for family bonding. I like to stand up in front of the TV and act like what should be showing on the screen for my family's viewing pleasure.
Ok, I used to do that anyway. But my family left me for some reason.
