I turn on the tv and i get a blue screen for 5 seconds and the tv shuts off. Any ideas?

This is normal on vizios, ours does it too. You have it switched onto RGB input. You need to change input after it comes on. Switch on and keep pressing change input button till it changes and then it will be fine. Alternatively plug in a computer on Rgb and then turn on, you will be able to change input normally.

I have a vizio gv42l fhdtv10a I have no picture or sound.

Fault to the main power supply regulator section. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electro-medical.blogspot.com/ http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
