For the 46" TV, it sounds like the main board is bad.

For the 50" Vizio: is the LED light on?

Hi I have a vizio vt42om the logo lights up then goes off is that the inverter board or the power supply or just the fuse

Sounds like main board fault. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Vx37l stopped working with FiOS remote

I read in another forum where Vizio sometimes uses Vidtech codes. I got 0205 to work on my new Vizio V037L with my Verizon FiOS remote (Phillips RC144).
