I really liked this model for it's tasteful styling and sound, but I've had obnoxious problems with defective displays on this unit (disappearing segments). On the third unit (first two failed so quickly that they were exchanged for new), I've just been living with it, but it is getting worse and more annoying.

Anybody know what the problem is in this unit? Is it something that can be remedied DIY, or does anyone know a good place to service them?
