I was just catching up on this thread and while my timing is not the best, just wanted to make the point:
(For me at least) that ADTG's Denon pre-pro died at 8 years is not so much a travesty. The travesty is that "all the King's (Denon) horses and all of the King's men could not put it back together again".
Knowing the manufacturer was unwilling/cannot repair a $7500 pre-pro is a bitter pill to swallow and very difficult to understand! Most modern design uses modules and while old-timers often resent that you have to replace an entire module, it usually makes trouble-shooting/repair a much simpler task.
I am suspicious that there is more to the story.
Perhaps one of the EE's or guys who has been in the industry can offer some type of explanation of why it would be impossible/impractical to fix this unit?
According to the Denon Repair Center, they replaced the "Audio Video Board", which they said cost about $1,000.
But that did absolutely NOTHING to fix the problem (assuming they did replace the "Audio Video Board").
Thank goodness, Best Buy gave me a full credit for the $1,000.
The problem with the AVP-A1 is that it has like 20 circuit boards (okay I didn't really count
),but it seemed like there were 20 circuit circuit boards when I took it all apart (after I totally gave up and it had zero volume output and HDMI board no longer worked also).
It was a messy jungle inside the chassis.
With something like the Theta, DataSAT, ATI, Bryston, there are very few boards/modules.
If it were built like a clean full Tower PC where there's only 1 main MB and the rest are modules/cards with plenty of room inside the chassis, I bet it would be a lot easier to diagnose the problem and replace that faulty MB or one of the modules.
BTW, Grassy said he was going to send his dead AVP-A1 for repair also. Will see if the techs are able to fix his AVP-A1.
