YOu could try rebooting the box. But give them a call. Note for some such problems with boxes you don't even need to talk to someone as you can get their automatic repair to do some functions that fix ONT problems.
ps: Suggest you use a cell or other phone to report problem, as even if phone service is currently working it may well go down while you are trying to repair problem.
You most likely have a problem with the "main box." If phone service is out too, that definitely confirms the problem. Regardless, you should call Verizon tech support.
Assume you mean the Opticial Network Terminal (ONT) when you osay "main box." That's what it's called. There is a reboot process at this link.
The OP used the term "main box." He also referenced the MGMT, MGWK, Vld and and FAIL lights. I've never seen such lights on an ONT.
My best guess is he's in an apartment building slaved off of a MDU with a VDSL modem/router, however I'm not familiar with the lights on them. Since it really doesn't matter weather he's on an ONT or VDSL modem for this issue, I didn't want to waste time with terminology. Thus, I stuck with his "main box" title and left it in quotes.
Bottom line, the OP most likely needs to call Verizon to fix what is wrong with his service.
