So i bought a pair of used fatshark hd3's. They were working perfectly woth laforge module. Today i was trying to take the goggles apart and run the laforge wire through the goggles. (previously it was running from outside) Now when powering up my goggles, the screen is just gray, no static. Its most definetly not a power issue since the buttons work. And also the the module wont turn on

There are some delicate cables running between the two parts of the goggle shells including a ribbon cable in the middle. You can see some of those cables in a pair of HDO goggles in another post HERE.

I suggest you open up the goggles again and make sure you haven't damaged any of the cables and that the connectors on both ends of all the cables are seated properly in their sockets by carefully unplugging and re-plugging the connectors to re-seat them.

Did u find a solution?
