About Broken X-fi Titanim Fatal1ty Pro - How can i fix?

[hknymz]

Hi,
I need advice about fixing SB0886. Optic output working but no anolog sound for all channel. I bought this card today very bargain price, maybe i can fix it

Thanks

[ROBSCIX]

It might be fixable but it might not be, it depends on what is wrong with it.

Do you have any electronics experience?

[GenClaymore]

It could be the op-amps used for the audio output.

[hknymz]

i am not electronic expert but i can clean soldering opamps and capacitors
and another thing is occasional flashes illuminated logo on the card , sometimes no light
i will change first opamps with soic to dip-8 then power caps.

No frontal out ?

[ROBSCIX]

I would test the outputs. Try stereo first, surround, quad etc....if all the output are dead,I seriously doubt it is the opamps, so no sense in replacing them.

you mean i need to change only opamps?

No, you said you were going to change the opamp, so I said, I doubt it is the opamps that are causing the trouble.

The card is probably damaged beyond repair...

"It was very bargain price." LOL
There was a reason for that. Bin it!

this one SB0886, marked with red circle more darker than sb0880

Capacitors won't make a difference if there's no analogue - check the power supplies to the DAC / analogue section first.

I suspect either DAC or power supplies if there's no analogue on any channels.

Opamp failure would only affect 2 channels at a time - unless they all went at the same time, capacitor failure would (at worst) give increased noise on the output - but the PSRR of modern opamps is so good that you might not ever notice.

TL;DR? Check power supplies.

which ones power supplies?

[ROBSCIX]

The real problem here is you don't have the tools or the background to repair the card.
My advice is to trash it and get a new card, save your time and energy.

You could always try baking it! Works for graphics cards at least. Probably only worth throwing out unless you want its digital out.

I'd check opamps - DAC - card in that order. You'll have to look up datasheets so you know which pins are which, though most opamps will be 4 and 8.

Other things to check are

- Damaged connectors (wire and PCI)
- Continuity between analogue and digital grounds - resistance should be a few ohms.

You'll have to test the supplies while it's powered up and installed in a working system, which is a bit risky. Only do it if you're 100% on what you're doing as one slip could ruin a lot more than just the card!

Edit: This info is how i'd start, but i'm obviously offering no garuntees. We're all happy to help, but if you blow your mobo or power supply you're on your own i'm afraid!

Only you can decide if you're up to tackling this. You'll need a steady hand and some VERY thin probes as an absolute minimum - don't even think about poking around on it otherwise.

i will change this dac :

what do you think?

[hknymz]

or this one?

[ROBSCIX]

What makes you think the DAC has issues? This is why I said you need the proper tools.
What you would do is take a signal generator, send it through the card and find the point where it terminates. Fix that area.

Most DAC's are not pin for pin compatible anyway.
You can have fun experimenting but if you are changing the DAC hoping that is the issue, i would verify it first. not to mention you are going to have serious trouble getting it off the PCB and soldering on the new one unless you have a really good soldering hand.

[HyperTension]

I have the PCI version sitting in a box unused for over a year if interested..

[Tom F]

You can't just randomly change stuff - you're not going to fix it that way.

Measure the supply voltages, tell us what they are and we can help you from there. The last thing you want to be doing is changing IC's because for a big one like the DAC you'll just ruin the board unless you know what you're doing.

Find the fault before spending money on new components...

I don't think the OP has a clue what he's doing.
