OK....now I know why it was in a garage sale. The unit turns itself off randomly. It seems like maybe some is loose though. When it is off...nothing responds until I hit the bottom back left side and then I hear a click when the unit gets the power. Right under the power PCB. Any Ideas? ANy engineers out there know how I can test the PCB to see what the issue is? Ive taken it apart and it looks fine, but the unit just shuts off in the middle of a song, at the end of a song...doesnt matter. It just turns off randomly.

You were right, the ID3 tags were all missing. I grabbed the boxes of CD's and re-ripped all of them. Now it works fine because the new rips have all id3 v1.1 and v2.x. Thanks for the help. Now if I can find a new power supply, maybe this thing will work 100% again.
