Re: Vizio VO47LFHDTV10A - No Backlight
Also, when you say the main filter cap in the primary side, is there a number for that on the board?

Re: Vizio VO47LFHDTV10A - No Backlight
Thanks budm, I will check this and see what I find out. When you say to check and see if I have less than 380VDC between the two legs, do I need to put both the positive and negative leads from my multimeter on them, or do I put the negative lead on the chassis ground? Thanks

Re: Vizio VO47LFHDTV10A - No Backlight
My main objective is to fix the TV. But also learn some things along the way. Does anyone possible have a schematic for this board? That would be a HUGE help.

Re: Vizio VO47LFHDTV10A - No Backlight
Thanks dskall, I'm not very familiar with motherboards, so I can't really check the other components without instructions to be honest, but I can re solder that coil and possibly other things in that area. What other than that coil would be important to re solder?

Ok. Will do that this afternoon when I get home and let you know the results. Thanks!

Re: Vizio VO47LFHDTV10A - No Backlight
Ok thanks! So would it be a good idea to completely re solder that whole coil? Anything else I should re solder to make sure?

Re: Vizio VO47LFHDTV10A - No Backlight
dskall - Sorry, but could you please explain what you mean when you say inductor? are you referring to the small "coil" that is burnt, or do you mean something else.
budm - yes, looks to be an exact match!
Speaking of that board you found, I just realized that on my board, two the solder points right below J5 look to be soldered together! On the new board you provided, if you look at the back and zoom in, those two points are separate! Do you think it got so hot that it fused them together!?

I am getting about .2 Volts to nothing on the 24 volt pins.

No. I do not get either results. I did however get sound. At least the last time I checked. Haha! I have messed with it several times since then!

Re: Vizio VO47LFHDTV10A - No Backlight
Here are the two pictures. The blue capacitor you will see in the picture is the first one I replaced. It is that same uf and voltage as the original one....

Vizio VO47LFHDTV10A - No Backlight
Good morning all,
I have recently received a Vizio 47" Tv model: VO47L FHDTV10A
I have done a significant amount of research lately, and still cannot figure out my problem.
Here's the problem,
On the power supply, I had one bad capacitor with one burned coil and the surrounding area of the board was burnt (about an inch or so in diameter). I have since replaced the capacitor. Further down the line, I have replaced the two bad capacitors on the two different inverter boards with 1000uf and 35 volt capacitors instead of using 680uf...
