Huh? Highlight it please.

Tom66 I posted the picture of voltage regulator I was testing again see post #40 Didn't post the fist time

Re: Vizio E552VLE turns on then off

Uhh, that's not a voltage regulator. You won't find those on most power supplies. You can try replacing the fuse and you may be fine but more damage may have been done.

Tom66 if that's not the voltage regulator what is it. there is 7 of them see pictures. So then where are the voltage regulators?

Tom66 here's the part number off the part I was testing K12A500

Re: Vizio E552VLE turns on then off

They are high voltage MOSFETs. Don't need to be tested, especially not while live.

Thanks tom66 hope the fuse is the only thing smoked

Tom66, how do you change this fuse ? I can't find the fuse with the cap and wire on the end. If I desolder cap on end of fuse from PCB will it come apart to install a new fuse or do I have to buy one set up like that for through hole soldering on PCB ? see picture of fuse

Re: Vizio E552VLE turns on then off

Desolder the fuse, replace it with a new one with leads. They are available search "wire leaded 5mm x 20mm fuse".

Re: Vizio E552VLE turns on then off

I believe the regulators Tom was referring to are the regulators on the main board.

Tom66, been looking for the fuse T6.3AH/250v. Can find fuse but I can't find it with the lead I have looked at e-bay,mouser,digikey and on the web.Maybe some one knows where to get it.

Search for pigtail fuse.

tom66,found this fuse at mouser

#693-0001.1010.pt

cartridge fuse pigtail
4.A
ceramic
fast blow
5x20
Will this work as a replacement?

[tom66]

Re: Vizio E552VLE turns on then off

4 amp rated so probably not a good idea to replace a 6.3A with it.
Ask others please not just me!! There are tons of great helpful users on this forum.

anyone know where to find this fuse T6.3AH/250v with a pig tail. thanks for any help

This is what you need

Pretty sure Tom will be right though, blowing that fuse is most likely not your only issue after shorting that MOSFET

i have exactly same problem turn on few seconds then off.. ok it was good the forum i got some ideas where can i find the problem on this tv, until the whole forum focus on where to buy a fuse and how we replace it,, come on guys we suppose to be electronics or at least we all have some skills lets focus on the problem thanks
