Not much since the IC is blown due to the fact that the Gate/Source was showing 1.8 Ohms, the high Voltage was high enough to break down the Gate/Source insulator inside the MOSFET (https://cdn.badcaps-static.com/pdfs/...a0d6f3418e.pdf) so that IC could not have survived.
You are better off with new power supply at this point.

OK, Thanks for the help, I just can't see getting $50-60 invested in fixing this one, when I can get one with 2 year warr. for $70.

Thanks again,

I have the same exact tv but the Vizio will light up orange when I plug it in but won't turn white when I press the power button and the tv won't turn on.

Hi all;

I have the same board and it has lots of fried components.

- C901 ceramic cap (331K,1KV) I couldn't find same one thus I replaced with 471k,1KV. I hope it won't cause big trouble.

- R902 (0.68 ohm) I couldn't find similar resistor thus I used ( 0.33ohm + 0.39 ohm two resistors.

- R906
- R907
- R908 (If I didn't read wrong, it should be 69A)
- D902 (I think it is A6)
- IC900

Unfortunately shopjimmy doesn't sell IC900 replacement.
Since this ps board became black-marketed, replacement boards has $109 price.

If any of you have data sheet of 0500-0407-0680 PS board and share it, that would be great .

lambo300zx; since you have active ps board, I would take a look at this video (https://www.youtube.com/watch?v=cNFzBJELFoU) to check your board. I know it is not same board but it may guide you to find faulty components.

If you may let me know color code of (R906) or numeric codes of (R907, R908,D902,IC900) written on them, I really appreciate .

Thank you for your time.

I did the same for my tv. Its piece of s... I checked diodes of all board including smds and %90 of them burned. Funny thing is since there is a serious burn issue, the fuses are still working. Good thing like all others i didn't invest $90 replacement board on tv. With this quality most probably it would burn as well.

I have the same tv with the same issues. Does anyone know if there is a replacement for the ic 1D08801? I couldn't find any info on it.

Does anyone on this thread have a damaged Vizio VO47LF 0500-0407-0680 PS board they would like to get rid of? I need only the inverter transformer in working order. Mine burned out.
