Old thread bump:
I have a T175HD with the AM200 and VM200 cards that recently began giving me issues. Running DSP v1.34. It is out of warranty.
The display will show “CHECK DSP BOARD
” and not pass any digital audio for approx. 30-45 minutes until the unit gets up to normal operating temperature (rather warm) – then the error goes away and the unit begins passing digital audio again. “Analog Bypass” seems to work fine while in this error state. I also randomly hear pops - sounds like digital clocking (sync) issues.
Sometimes, the front display won’t show ANYTHING and won’t even pass HDMI video to the TV for 5 minutes, and then the display turns on, passes HDMI video, and then displays the “CHECK DSP BOARD” error for 30-45 minutes (until warm). Seems like more than just the AM200 card might be affected?
I’ll admit the issues only started when I removed the MDC cards to thoroughly blow the unit out (maybe a static discharge happened?) – so it is likely something I caused myself – but I have seen other reports of these T175 issues with a Google search (no associated resolution to be found
). The temperature aspect seems to be an odd symptom for a static discharge fault, no?
Any pointers? I tried multiple factory resets, I re-seated all cards again, and double checked all grounds – everything looks OK. I have also tried re-flashing the firmware after the unit warmed up (flash successful followed by factory reset), but same issues occur until the unit is warmed up. I also tried disconnecting EVERYTHING but AC power to eliminate external variables and have the same results.
On the recommendation of another AVS member, I already have a Denon AVR-X4000 on the way (mainly for the Audyssey X32, but also because it was only $850 as an open box w/full 3 yr warranty!).
A new AM200
DSP card for the T175HD is $600
– and I'm not even sure if that will resolve all of the issues. I figured $850 for an entire AVR with superior Audyssey and additional bells and whistles was likely a better prospect for my hard earned cash. I don’t even use my AVR for “Critical” 2Ch audio playback (mixing and mastering audio projects), so I’m sure the X4000 will be plenty sufficient for my HT needs regardless. But I'd LOVE to get the T175HD issues sorted if possible...
Anyone have a AM200 (or even an AM100) card they are looking to sell CHEAP?
Thanks for your time – and have a nice day!
