My Lowdown LD 150 powers on with a nice thump but there are no lights and none of the controls work. There is a light buzz from the speaker and plugging an Ipod into the 3.5mm jack produces sound (but still with no control from the front panel). The two input jacks on the front panel don't work at all. I've had a look inside, tested all the voltages I could with a digital multimeter and they checked out fine. I wasn't able to definitively check any capacitors but visually they looked ok. An internet search revealed at least two other people with exactly this problem but no solution. So..... any ideas?
