Good evening I am having issues with my k4306 did my wire up and first time I powered up all the lights on both sides lit up and stayed lit, went back to it today to check all solder joints to check for shorts etc. Then powered up again this time no lights at all can’t get anything? Any ideas dan
I too have a problem with my K4306.
On the Right Channel the Yellow LED (+1db) lights at the same time as the Green LED (-6db or could be -4dB) I am in Bar mode. I have tried to find any solder bridges or shorts. Could someone look at the PCB artwork and see if there are any tracks which run close to the Yellow LED ?
Regards
Alan

Hi All,
I found the problem to the Yellow LED on the RH channel lighting up at the same time as one of the Green LEDs.
Looking at IC6 there is a short between Pin 17 (no connection) and the tracks which links pin 14 to Led LD22.
I did try to separate the track from the un-used IC pin, but found it easier to cut both ends of the track and replace it with a insulated wire link.
I took a photo before I built the kit and looking back at the photo I see it is a PCB manufacturing fault.
