MinimOSD does not work

Yesterday, I received my MinimOSD V1.1 from Hobbyking. I connected everything and the OSD has worked properly. But now, (I only has removed the battery in the meantime) it doesnt work.

Did anybody know, were the fault is? I checked every connection serveral times :cry:

@Glasses,
Your post was moved to this sub forum because your MinimOSD is not a 3DR product as you bought it from HK.
