Bluestone, I have recently experienced the same problem and, unfortunately, that's not correct. I called that number and, IME, if your warranty is expired, Line 6 will direct you to a service center and tell you "good luck". You will have to pay for the parts and labor. The main board will run you about $90-$100 US. Labor varies from shop to shop but it will probably run you at least $75 for the shop labor. You could easily pay more for the repair than the amp is worth. My 2 1/2 year old Spider III 75 which is in mint condition except for the black box problem, is going on the scrap heap. I'll probably strip it for any useable parts (speaker, handle, corner protectors, knobs, grill clothe, etc) and trash the rest. This has been my first experience with Line 6 products and it's been rather disappointing. I've had much cheaper amps that have lasted much longer (and are still working). Live and learn.
