Re: Replacing unknown NTC Thermistor in Corsair CX400

Indeed, there is certainly no relay and I've not seen a Triac in there either.

Re: Replacing unknown NTC Thermistor in Corsair CX400

I had a look at this again yesterday, after being annoyed by it and leaving it in a corner.

The design is such that the primary filter capacitor is initially charged via a diode direct from the...

Re: Altec MX6021

Can you post photos showing these parts especially C25?

You can't test capacitors in diode test mode except for a short so the results are meaningless.

Re: Help an untrained ear to identify this sound? (unplugging a Hiper Type-R 480W)

For lifted pads on "easy" boards, you can usually fix them by just scraping off some solder-mask on the track with a sharp blade (don't push too hard!), bending the component lead over, and soldering...

Re: Help an untrained ear to identify this sound? (unplugging a Hiper Type-R 480W)

Have you confirmed that the short-circuit reading across the 5vSB output is now gone?
Did you be sure to put the diodes in the correct way around?
Did you check for solder bridges?

Can you post...

Re: Buying custom crystals...

Sorry to say it but you'll have to get used to SMD sooner or later... with the right tools its not all bad though. I used to hate SMD parts too. Now they only mildly annoy me.

I actually like them...

Re: ASUS A7M266 Kills T-Bred B??

What cooks itself? The CPU or the VRM?

Maybe you've managed to short both CPUs now or the VRM controller is instead\also damaged.

Did you try the CPU in another board?

Re: ASUS A7M266 Kills T-Bred B??

So maybe you have bad VID signal to the VRM controller. I get the impression you are trying to use an unsupported CPU as well?

Re: Buying custom crystals...

That's what samples are for! It's a free test. Even if you intend on mass production there's no guarantee you're going to use the same chips you prototype with. The design can always change.

And,...

Re: Let's talk about BGA Chip suppliers

Good information! I have bought from SEE-IC before, via eBay, and found them to be decent.

Re: Cooler Master RS-350-PSAR-13 dead

Post a photo of the underside of the board so we can find out which parts are actually in the 5vSB circuit... checking random parts blindly won't help if you don't know which circuit they're in.

Re: Cooler Master RS-350-PSAR-13 dead

Don't know, can you post photos showing the 5vSB circuit? Could be bad capacitors on the 5vSB too.

You haven't actually got a short in your PC on that rail, have you?

Re: Film caps installed the right way

Maybe not. Around the 'wrong' way just means the capacitor may pick up a little more electrical noise and cause the audio signal to lose quality. It's unlikely to cause an actual fault.

There is...

Re: Matsushita blue caps from 1991?

If they are only power supply capacitors, then I think there is even less chance of anything changing.

If the capacitors are in the signal path, then change in properties like ESR, ESL etc may...

Re: Matsushita blue caps from 1991?

My understanding is that changing the type of capacitor *might* change the frequency response of the amplifier to some extent, such that there may be a different "colour" to the audio. Such a change...

Re: can anyone explain how this protect circuit operates ?

Well... from what I can make out from it:

The output from the protection IC, IC101 provides feedback to Q120 via R108(?), and by extension, Q101/Q102. That seems logical enough. Normally that...

Does Q117 actually have anything to do with bias? Or is it just for driving the protection LED?

Re: Soldering Equipment

Define reliable.... It's cheap Chinese gear. It'll work, but it won't be amazing. On the other hand, spare parts might be cheap, too!

I'd personally go with the basic analogue versions. Less stuff...
