L37 vizio lcd

I have a vizio model L37 lcd tv.When I plug it in ,it will only show a green light.I pushed all of the other buttons on the front it still does nothing.The screen is totally black.I heard of some other people having the same problem.They are saying that they think the main board in the middle with all the connectors on it is bad.I have the numbers that are stickered on that board.They are 3370-0082-0150.It was manufactured in March 2006.Do you think this might be my problem as well or do you believe it to be something else. Thanks, screen name pcrane1

    Hello,
    I ordered and replaced the main board but still no picture or sound or anything.The green power light is still on but a totally black screen.Do you think it could be another board?
    Thanks Paul

I think that you are correct in thinking the board is bad since the screen still works otherwise. Many service men have reported similiar problems. Call Vizio at 877-698-4946 for help and to verify this problem and order parts and if it is still under warranty, then you can get a replacement tv

Check the owner's manual before consulting other sources. Often, the possible problems are laid out right there, along with a troubleshooting guide.

Check the remote control and replace its batteries if necessary.

Check all the connections - AC plug into the wall, cable television connection, input and output cables to other machines such as VCRs. Unplug or disconnect them, then plug them in again.

Take the television for professional service, if necessary. It's better than nullifying the warrantee or ruining the machine by attempting repairs yourself.

Do you see any burn marks or leaking components on that board? If the TV's power supply thinks it's on then it would make sense that the problem is on the main board. I've seen it here for sale: http://www.vancebaldwin.com/products/?3370-0082-0150 $126 bucks, not bad.

First try to look really close at the screen to try to see if there is faint evidence of a picture, if so then the problem is with the FL inverter that drives the backlight. But if there is no sound then it's not that but the main board. Good luck!

    I would think that if the mainboard did not rectify the problem then the next logical step in the chain would be the power supply board if there is one.

Yellow light is so I have power but remote or


Its a vizio l37. I bought it in 2004 from Sams and haven't had any problems until now. We took it to a repair shop and they charged me $55 to tell me it was dead. They said they could fix it by replacing the main board which costs $250 with an additional $250 in labor. We said no thanks to the $500 repair and bought a new tv for $600. Now its in the garage and I'm wondering if there is something I can do to fix it for less. Seems like a waste.

Display controller is usually under the Main board which you remove to get access to it. Display controller connects to the suis-boards which then send signal to the screen of the TV.
