My daughter and I recently assembled the MK172 Soundstar kit. Had a few problems with couple of the copper solder circles on the PC lifting up, but was able to trace the circuit and make connections with wires. All LEDs light up continuously with no blinking at all. Tried both 9V battery and DC power source, both with same results. Need help.
I have downloaded the schematic diagram and used meter to trace through circuit and all the connections match the diagram exactly. Solder joints look good with no bridging. I read couple of other posts on similar topic. How should I proceed to troubleshoot this problem?
