Re: gigabyte GTX 760OC. no display.

No, these modern GPUs work off of the 12V rail only, which they then convert down for the GPU core, GPU secondary core / PCI-E comm bus, RAM Vdd, and RAM Vtt. The only place you will see 5V is on...

Re: Does flux expire ?? Flux discussion.

Yup.

Apparently, Kingbo is just another generic Chinese RMA flux, so the quality will vary. But from what I've seen myself and heard from others so far, it's anywhere from acceptably working to...

Re: Ps3 shutting down

Could use a little more details, like full model number of the PS3.

If it's a "phat" one, issue could be the GPU, the PSU (particularly if it has a Nichicon-made PSU), or those NEC-Tokin caps...

Re: 2x EVGA 970 with same issue

You have GPU chip failure on both of these cards.

Might be able to revive them with the hot air station if you do a "reflow", but don't count on it... and if you do, the repair likely won't last...

Re: gigabyte GTX 760OC. no display.

If this is a problem that appeared "out of nowhere" in a PC that it's been working fine in before, and if the PSU is a known good brand (and no bad caps inside it)... then most likely the GPU chip on...

Re: Seasonic X 850W not turning on

:confused:
Can you point it out? I don't see it at all. I've seen caps (both solid and wet electrolytic) get their cases trashed a lot more and still work fine.

Re: Reballing discussion and tips

I've actually tried that before. The chip will solder to the board, but very unreliably / not all contacts in most cases.

Reason why is as diff mentioned - you're not going to get nice balls on...

Re: Badcaps.net Origin & Roots - Topcat's VP6 Thread!

Nice work, as always. ;)

Is this going to be built into an official system, BTW? I don't see an audio card, so I imagine this setup was just something to test/evaluate the system and not so much a...

Re: Seasonic X 850W not turning on

Re: gigbyte h61m s2pv 2.2

Shorted MOSFET typically trips the PSU into lockout. So I don't think that would be the problem here.

Would try all the usual easy stuff first: minimal hardware, known good PSU + RAM + CPU, test...

Re: Soldering station thoughts and guidelines

I agree.

I have a 60W soldering gun and I've never found a good use for it, especially now that I have a T12 station. But even before I got my T12 station, the thing was just never any good. I...

Re: Badcaps.net Origin & Roots - Topcat's VP6 Thread!

Re: best cheap/free scores 1.1

Re: Computer jobs that are like kicking yourself in nuts.

Yup, that's how modern laptops are these days - that is, battery is inside and it's almost always now a "softpack" instead of using 18650 cells... hence almost always bulged when it starts going bad...
