So I have my PVS 1431 mounted, sitting on my rifle safe. My toddler pushed the helmet off the safe (along with the mounted nods). I put a few AA lithium in (like always) and nothing, black screens in both tubes. Tried different batteries and hooked it up to my battery pack, nothing. Any ideas? I have a warranty but the lead time from the company I bought them from says 180 day lead time, but for new purchases.
