I have a 47 inch Vizio with voltage issues. The TV model number is VO47LFHDTV. The power board is 0500-0510-0340. These boards are pretty expensive compared to how much I paid for it so I'd like to fix it myself.

I would like to find out what the value of a component on the board is. It is an inductor that got hot, burnt my board, and I had to use jumpers and solder to fix the circuit. After fixing the circuit and replacing all bad caps I noticed a spark on the inductor from one wound spot to another so I'm assuming its bad since it black, not copper looking. If I could get schematic of this board or a parts list of this board or any help into finding the value of this inductor or lead me in the right direction ANY help would be fine.

Here are some pictures of the area of the board that has the bad inductor. Note: These pictures are not mine, but same board with same issue, but mine is worse.

The part that is bad is L240A and possibly L240B. Ive replaced everything else. If you need any more information at all please let me know and I will provide anything needed.

When both master and slave inverters are plugged in I get no voltage. When I unplugged them both I got 12 volts, but my voltage is supposed to be 25 volts.My inverters might be bad also from this short circuit, but without the inverters plugged in I'm assuming I should have my full voltage. Please correct me if I am wrong or if I am missing something here.

I'll see to it that you receive a full refund on your request for free advice. Good luck with your TV.
