K8095 without LCD

I have recently completed the K8095 MP3 player kit (without LCD) and need some help please to get it working as I am only getting white noise from the speakers.
With no SD card, only LD4 is lit.
With the SD card in place, LD4 and LD2 are lit. If I press the play push button, then LD2 sometimes goes out whilst the switch is pressed and then back on again.

This is all OK.

This can indicate that there on the SD card are no or not valid MP3 files.
Or maybe not compatible or defective SD card?

Thanks for your help. There was a problem with the SD card as you suggested. I reloaded and relabelled the MP3 files and folders and it is now working.

No problem. I’m glad you resolved the issue.
