This goes to Front board and m67559 to Main, where voltage regulator U produces 5V for microcontroller. Local NAD distributor says that the part is obsolete. South Africa Line Voltage: U heats very quickly.

No external Flash or ROM, so its program is in internal flash. United States Line Voltage: Thanks, I already had these documents before posting my message. Find More Posts by Longbow. The time now is This sucks, Aki know.
All times are GMT Remember that this was a storm failure, so it was too good to be true that only microcontroller was hit. But then Mm6759 see that 5V rail in front board is shorted! The big problem is, of course, how to program that IC internal flash.

Same thing happenedlightning storm and nothing was plugged in Checked again all connections that I touched on first repair and everything was fine. This comes from a 74HCD multiplexer U that selects one from 6 digital inputs. Find More Posts by keeney Windsor ON My Country: I noted the post was inbut taking a chance here.

NAD support in South Africa went for runner. I guess it depends on how much you enjoy music from it and if you can afford it. The basic rule of thumb here is that lightning doesn’t break just one IC.

This complex and crappy receiver is dead after a storm. Definitively my most frustrating repair of I received the pair of controllers last friday, I replaced them and now it works fine. Still it is cheaper than a refurbished unit or a new one. Originally Posted by keeney
