I put together the k8098 audio analyzer, and when i plug it in, the only thing that happens is that the backlight of the display lights up, nothing else. Can somebody give guidance for troubleshooting? Is there a hi-res photo of the back of the PCB so that I can check my work for inadvertent solder bridges?
Most likely an assembly problem.
Make sure PIC is correctly inserted.
Check if +5V arrives on PIC.
Sorry, this forum does not allow picture uploads
If you can provide LINKS (e.g. by using a free online picture base) to HI-RES and SHARP pics of your assembly (both solder- and component side)
then we can take a look and provide some feedback.
