I need help with disassembly of Vizio GV42L LCD TV
Hi, I am swapping a smashed LCD with another one I bought locally as a non-working tv with a good LCD. I have removed all the screws but I can't seem to take the back panel off to get inside the TV! Any help or tips on how to remove the back off of a Vizio GV42L LCD TV?

Remove all the screws and start at the bottom and push in the tabs, and work around the edges, being careful not to pry too hard, the cover has clips all around the tv. after the bottom is free and one of the corners the cover will kind of pop off if you use the palm of your hand and lightly tap as you apply sum upward pressure.

No picture/no sound condition could be caused by either a faulty power supply or main board. Proper electronic troubleshooting will need to be done to verify. If the set is under any kind of warranty, return it ASAP
May be a bad power supply, which is a common problem with these units.I have a GV42L 42" manufactured in march 2007. It works perfect except the screen has a fracture on it. The warranty is voided because we damaged the screen. I can sell this to somone who has a good screen but needs boards or speakers, etc. Or I will buy your tv that has a good screen but damaged boards in it. firstname.lastname@example.org
I had this same problem. Vizio sent someone out to replace the motherboard. It didn't fix the problem. Since it was under warranty, they replaced it with a newer model VU42L. Doesn't have this problem, but it has others.
You can have them repaired using a TV Repair guy but often it costs as much as a brand new tv. My daughter broke my $1,600 LCD. It would have cost $1,200 to fix.. so I just bought a new one.After that I picked up a TV screen protector called TV Armor http://www.tv-armor.com Its designed to protect the TV from damage. Now I dont have to worry anymore when she is playing near it. It works really well.
If you are using a set top box this might be caused by turnig the box on at the same tie as you turn the tv on or slightly after you turn the tv on. If you are using compnent or HDMI inputs the set needs to see the signal as it is turned on to know what formt the signal is in.
