okay, I will tommorrow night, since I have to go get my dads camera.

but like I said, 1 of the 4 transformers (they call it(?)) is extremely hot, so that resistor failing could be it. Is the legato board the lcdbs? I have two lcdps board, on which each board have two black thing (i hope people understand what I mean), and on one of the board, one black thing gets super hot, and the other not, and on the other side, both remain relativly mildly hot...

ouff I feel a bit release as I feel we located the problem. thanks guys and I will post the pic tommorrow

The "Black" things are actually Heatsinks for the Voltage Regulators.

The LCBPS is not the Legato Board. The LCBPS is the power regulator board to supply power to the DAC or Legato I/V board.

Since you do not really understand what is what, a photo will speak a thousand words.

Okay, I'm back from work.
I talked to the seller and he assure me that the DAC was working perfectly, but how do we know for sure.


pcking: how can you know that the problem might come from the capacitor? How can I find the problematic caps? Do you want any specific picture from the dac, what parts do you want to see?

Brian: have you ever experience with the problem I'm describing?

thanks

Hi Jason, I didn't say it was capacitors. I said it might be the resistors. I had a similar problem on my Legato.

An overview photo of the entire DAC would be good for now. It's basically to determine what you are having besides the BuffaloII DAC board. Or maybe you can ask the seller what are the various boards in your chassis.

I don't think it's the DAC board that is having this issue.

Do you have a DVD player, or CD player with a digital output? Try playing a CD through that into the Buffalo just to see what happens. Using computer audio there are too many variables to isolate your issue. If you have the problem with both sources, I would continue to diagnose the Buffalo using a digital source with fewer variables.

I'm going to get a cd player tonight with digital out, since I dont have any.

But in the meantime, can someone tell me if its normal that only one heatsink gets really really hot, while all the other are just slightly hot...

Yes. The side of the LCDPS that is supplying the Buffalo will get hot because it is delivering a lot of current.

Hmm... Since U have the Legato, there is a very high possibility that it's due to the resistors once U can confirm the problem is still there even with a CDP/DVDP as source.
