Re: Vizio VW42L -No Power/Fuse keeps blowing
what do you guys think?? Since the TV is blowing fuses and I cant seem to locate what is shortening out, should buying a new power supply board fix this problem??
Just needing some advise...

Re: Vizio VW42L -No Power/Fuse keeps blowing
Hey guys
It seems like the issue with this TV is isolated to the power supply board. How much would a new power board cost? I still can't seem to figure out which components are shortening out.
Do you think that a new power board would fix the issue?
Thanks,

Re: Vizio VW42L -No Power/Fuse keeps blowing
I checked my fuses, here is what the marking on them were:
[U]original fuse in TV [/U]- T6.3AH250VP (ceramic fuse)
I'm not sure what the "T" in front of 6.3 is and what the "H" and the "P" represents.
[U]replacement fuse from Radio Shack[/U] - 6.3Amp 250v Slow Blow (Glass Fuse)
Does the replacement fuse appear to be the same rating as the original?
If they are the correct ratings, what should I do next?
Do I have to...Last edited by vote4pedro; 08-02-2012, 09:34 PM.

Re: Vizio VW42L -No Power/Fuse keeps blowing
Hey guys bad news, I got the new FET's in the mail and I soldered them in. I replaced these 3:
[U]Q801[/U]
20N60C3
[U]Q601[/U]
P11NK50ZFP
[U]Q602[/U]
P11NK50ZFP
I put in a new fuse and when I plugged the power cord into the TV, the fuse blew instantly again. I'm using the same fuse rating only difference is I have a glass fuse and not a ceramic that came in it.
You have any ideas? I will have to remove the power board, I will post some pics...

Re: Vizio VW42L -No Power/Fuse keeps blowing
I'm having a little trouble figuring out which one of these I need to order. I have
this one below that jetadm123 helped me find. What is the difference between SPW or STP.
The other 2 FET's started with [B]STP[/B]11NK50ZFP that I will be ordering.
This one starts with SPW
[U]SPW20N60C3[/U]
[url]http://www.digikey.com/product-detail/en/SPW20N60C3/SPW20N60C3IN-ND/509556[/url]
just curious, I wanted to make sure I was buying the correct item.
Thanks againRe: Vizio...

Re: Vizio VW42L -No Power/Fuse keeps blowing
Is there a datasheet for this part available?
[U]Q801[/U]

Re: Vizio VW42L -No Power/Fuse keeps blowing
The chalk trick worked.....
Here are the bottom numbers from the Q801 FET that I thought
just had an (2) (E)
The bottom numbers are:
[U]Q801 [/U]
20N60C3
GKE717
I attached a pic of it.
Thanks alot...Re: Vizio VW42L -No Power/Fuse keeps blowing

Re: Vizio VW42L -No Power/Fuse keeps blowing
Thanks for the data sheet. I have attached a close up pic of the 2E FET. I hope you can recognize this.
I had a dumb question about ordering, I have also attached a word file with my ordering question. I didn't know if i needed to be concerned with the bottom numbers when ordering these?
Thanks alot...

Re: Vizio VW42L -No Power/Fuse keeps blowing
When I read the bridge in Ohms with it out of the board, i get (502.5 K ohms) across the (+) and (-) pins. Is the bridge bad also?
Here are all the part numbers:
[U]Bridge[/U]
D25XB 60 BA475
[U]Q801[/U]
all I see on this is two circles with an (2) and (E) in those circles
[U]Q601[/U]
P11NK50ZFP
GK1EA V6
CHN 724
[U]Q602[/U]
P11NK50ZFP
GK2EN V6
CHN 723

Re: Vizio VW42L -No Power/Fuse keeps blowing
I have removed Q801, Q601, & Q602 from the board. Here is what I got.
[U]Q801[/U]
Pin 1-2 = 0.1 ohms
Pin 1-3 = 13.0 ohms
Pin 2-3 = 13.0 ohms
[U]Q601[/U]
Pin 1-2 = 10.1 ohms
Pin 1-3 = 0.1 ohms
Pin 2-3 = 10.1 ohms
[U]Q602[/U]
Pin 1-2 = 1.4 ohms
Pin 1-3 = 0.1 ohms
Pin 2-3 = 1.4 ohms
Does it appear that there still bad?
Thanks,Re: Vizio VW42L -No Power/Fuse keeps blowing
