ALI M6759 PDF

South Africa Line Voltage: I had the hope that only digital input multiplexer was damaged, but now it works OK and still cannot detect any digital input. Thanks, I already had these documents before posting my message. I guess it depends on how much you enjoy music from it and if you can afford it. This comes from a 74HCD multiplexer U that selects one from 6 digital inputs. This goes to Front board and then to Main, where voltage regulator U produces 5V for microcontroller.

I still have it sitting here, because lightning damaged something else in digital board and I found too overwhelming to face it. I received the pair of controllers last friday, I replaced them and now it works fine. NAD support in South Africa went for runner. The time now is Still it is cheaper than a refurbished unit or a new one. No external Flash or ROM, so its program is in internal flash. But then I see that 5V rail in front board is shorted!

The big problem is, of course, how to program that IC internal flash. Yea, that is a lot of money. Find More Posts by mmartell. Checked again all connections that I touched on first repair and everything was fine.

Is there any change you could forward the details of the supplier for this chipset for the NAD T? U heats very quickly.
