I have a vizio gv47l 10a that you can turn on and run for 10 to 15 min then it will buzz and the screen will flicker and go out.the buzzing seems to come from the inverter board, some times the left and some times the right. If you wait awhile
then it will turn back on and do the same thing. Can any of you help me with this problem thanks

I believe you mean 1 of the inverter boards, LOL. The buzzing can be an indication of a bad inverter or a lamp problem. If the noise is switching sides then I would be looking at the lamps first. Could be a bad connection, a burnt connection at the tip of one of the lamps, or even a bad lamp. Not an easy problem to find the cause without replacing parts. I would probably double check the voltages to the inverters also.

Let me also add that if your going to be poking around in there with the cover off be careful where you put your fingers. There is high voltage coming off those inverters to power the lamps.... 
And don't try testing on the output of those inverters.

Are you trying to be Van Helsing to my Darwin?

I'm not sure I get the metaphor.

If you protect him from being electrocuted how will he become candidate to Darwin Awards?
