Re: WMA 76 USER DISPLAY TYPE
Ally, you could have added this to your original post on this , it helps to keep things tidy. 😉
I take it you did try to cancel the Child lock function (often gets accidentally activated ) before you changed the module.
The child lock flashing normally means just that, the Child Lock is activated, to cancel, press and hold child lock button for five seconds.
You may find you have a perfectly good spare module now. 🙂
