From the front you notice the power saver light on left it is always on if plugged in. The red light on the right comes on when you turn it on. I noticed today that it blinks, not sure if it did that before, at least I never noticed if it did. The middle of unit is display as you can see it does not come on. Nothing smells I don’t see any caps that look bad or anything like that. I have a minor in electronics, so with some help I think we can do this.
