The need to watch A Christmas Story in High Def made me dust off the HTPC again. Somehow in its dormancy it lost the ability to do 5.1 and it broke the bracket for the heat sink. I have no idea how either one happened, but the heat sink issue shows how far good brands have fallen with their migration of components to China. The mobo is an Asus M2NPV-VM, which had a good set of features, but something as simple as the plastic bracket the heatsink mounts to being of poor quality sidelined movie night. We tried watching Ralphie and friends- and had just gotten past when Flick sticks his tongue to the flagpole when the screen went blue. Not the BSOD, but the projector showing no image. I restarted the PC and it happened again. Whenever something wacky like this happens, I suspect heat, and when I popped open the case, the heatsink on the CPU was loose- because of cheap plastic. I'm not sure what the proper repair is- probably finding a new CPU heatsink bracket and mounting it. But the mobo would have to come out, and I"m not sure where you find just a bracket for an AM2 socket, so I got out my racing safety wire and pliers and that sucker is on there well now.
Speaking of heat- while poking around my EP2500 was hot- too hot to the touch. That can't be good. I had done a trick of putting in a very quiet fan, and reversing it- so it pulled in cool air from the room and vented it out the back. What it seemed to do was clog the front filter with dust. I assume the hot case for the amp was due to lack of airflow. After cracking it open, I'm not so sure. I went ahead and restored the direction of the fan flow (pulls behind the amp, and vents out front), but I didn't feel any flow. I crack open the amp case again, and I suspect my 2 year old had been doing modifications as he is apt to do. I found a twist-tie stuck in the fan shroud, preventing it from moving. I thought for sure the fan would be burned out, but it spun right up when I cleared the obstruction.
When testing out the sound, I noticed some drops during speech of the movie. I wasn't sure if it was the receiver or the PC that was not processing the signal correctly, but the receiver certainly did over the SPDIF port of the HD DVD player. I started playing with the PC and got stumped. I finally had to revert the PC to do 2-channel sound to get decent playback. Tonight I found some updated drivers for the onboard soundcard and have 5.1 again.
I still have one more issue to chase down- that of the input to the sub. My Behringer BFD shows the input as being maxxed out. I assume as I was pulling and reinstalling the amp that something got knocked loose for the inputs. I'm using balanced cables between the BFD and the EP2500, but the subwoofer output on the receiver is just mono and I need to chase down that cabling. Should be easy enough to do.
But the big news of the day (Christmas) is that a buddy of mine bought me a Blu-Ray player. He's a theatreophile as well (many of my ideas for my home theater came from his excellent setup). Having recently moved, he's without theater and we've had him over for movies all the time. He decided to upgrade me to BR since I'm still angry from the loss of HD DVD, so this was going to be the only way he got to see high-def again. I need to reprogram the remote to handle the new device, and need to figure out how to get additional component inputs, but we watched our first movie on it tonight. Very nice. Thanks Brian!
