I have been going nuts trying to find why my system has been getting darker and darker. Highs had become significantly attenuated. I swapped out components until I determined my BDP-1 to be the culprit. I tried different cables into the unit and a different hdd. I opened the unit to see if anything looked to be amiss. I found nothing but did slightly pull the output card from the motherboard and reseated it. Plugged it in and found the highs had improved. I again opened the cover and thought about cleaning the contacts on the card but was nervous about removing it. Instead, I pulled the fuses and cleaned them with deoxit and alcohol. This proved to be a vast improvement.
I am wondering if it makes sense to clean any other contacts within the BDP-1. The results of a simple friction cleaning of the output board and a chemical cleaning of the fuse holder were significant; restoring my missing HF's.
Any advice?
