Question about Vizio VW42LF 42 in. LCD HDTV
You panel has a TCON (timing control) board which feeds the panel connector (1 or 2) inside the LCD panel, the picture information is then broken down inside the panel assembly via a connection board. You have 2 options: Replace the panel or toss out the TV. If you are going to toss out the TV, you may as well make a project out of it and attempt to fix it... what's the worst that can happen? You break it? It's already broken. So here's what I would do. Take the TV apart (photograph as you go if you are worried that you will forget what goes where). Remove the LCD panel and place it in a clean area. I would clear the kitchen table, cover the table with a soft blanket and then place a bed sheet on top of that to keep the dust and fuzzies to a minimum. Place the LCD on your work area and patiently and carefully take it apart. When you get to the connector board inside the panel, disconnect the panel connection directly above the black bar (should be a hinge style connector, a tab will flip upward to release the ribbon cable) and then reinstall the connector. You need to be careful here, these cables can tear if you get too forceful with them. After you reinstall the cable, go ahead and reassemble the panel and then the TV. If this doesn't fix it, you are back to option 1... replace the panel or the entire TV. Option 1 is more often the TV as the panel cost is close to or more than the TV. Here's an illustration I made for you to give you an idea of what the connection board is doing:
Then signal comes in on the red connector from the TCON then goes out to the panel on the yellow connectors. This is just an illustration, your TV may be a bit different, but the principle is the same. I hope this was helpful, best wishes.
