Hi folks,
I have an IK Multimedia IRIG PRO DUO which will not power up. I’ve tried it with the 2 AA batterys (3v line) and with a 9v bench power supply (9v input line) I opened it up and had a good look around. I don’t see any shorts or obvious comment damage. It’s pulling about 0.22mA when plugged into bench supply at 9v input no lights on . And it’s pulling 0 mA on the battery 3v supply. All fuses on the pcb are good. No obvious sign of component damage anywhere. I can trace the voltage past the fuses up to smd transistors but nothing then on the other side of transistors. Teo diodes back to back close to main fuse on 9v input are measuring 1.2v forward bias and open in reverse seems ok. . If I heat this area with iron I get power up to the blue lights. And looks like it is working. But dies away quickly when I remove the iron. I have tested the components on the power section and all seem good to me. It’s strange the 3v input has no current draw at all. If I was to post some pics of the pcb circuit and voltages would it be any help someone might under stand what is actually happening here.
Just wondering has anyone else had power issues with this unit and maybe had a fix.
This is a link to the unit I am trying to get working.
