For all of you who have a display problem on the DSP-A1, I just found some interesting info on how to fix the display. Get on Google, type in "servicing a Yamaha DSP-A1 Integrated Amp on You Tube" and up will come a fix-it tutorial on how to dis-assemble the front panel and what to do for the fix. It's by Bughunter, and is 18.17 minutes long. Very easy to do if you can solder connections; also explains what caused the problem in the first place.
I don't have a problem with my unit right now, but in case I do in the future, this is great info. It seems that this display problem issue has happened to many units, as I mentioned in my comments above.
