Question about Vizio GV46L 46 in. LCD Television
My Vizio GV46L after one year stopped working and it's not under warranty now. It seems like it doesn't get power. I already tried switching different outlets and power cords. Could it be a faulty internal power supply unit? Does anyone know when I can purchase one? Does anyone perhaps know how to fix it? Thanks.
This unit uses one of 2 power supplys the parts list is here https://www.vancebaldwin.com/shop/research_new/VIZ/GV46LHDTV10A.pdf
you can purchase the parts at www.vancebaldwin.com. but before you order the power supply check the voltages on the power supply you should have 24v, 12v, 3.3v, and 5v if you have all of these voltages then you may have a main board or panel problem.

You can contact the manufacture to purchase the power supply module.
However, there are other boards in the set that can easily cause the power supply failure because something went defective. It is also possible that the power supply is not defective, but it is in protect mode because of a failure on another board, or in some other device in the set.
The tech would follow procedure from the service manual using the proper instrumentation and diagnostics to determine the defective board(s). Then he would replace the necessary modules and or parts to get the set working again.
In the end if you try fixing this yourself, you can end up spending a few hundred dollars on a power supply and only find that it blows again or goes in to protect mode because the original fault was not determined and corrected.
