MOROVISION PVS-7, GEN 3, INTERMITTANT

Postby markleyelectric on Tue May 31, 2011 9:09 pm

I BOUGHT A USED MOROVISION PVS-7, GEN 3 OFF THE WEB, AND DISCOVERED IT OPERATED INTERMITTANTLY. IT WOULD BE FINE, AND THEN START FLUCTUATING IN INTENSITY. THE ILLUMINATOR TUBE SEEMED TO BE FAILING. I WAS CONSIDERING BUYING A USED REPLACEMENT TUBE, AND THEN I GOT THE BRIGHT IDEA TO SEE IF THE PROBLEM WAS AFFECTED BY TEMPERATURE. I TRIED HEATING THE NVG UP WITH A HAIR DRYER WHEN IT WAS MALFUNCTIONING, AND DISCOVERED THAT IT WAS INDEED, HEAT AFFECTED. THE PROBLEM SEEMED TO GO AWAY, TEMPORARILY, WHEN IT WAS WARMED UP. I THEN DISASSEMBLED THE NVG, REMOVING THE INTENSIFIER TUBE, AND HEATED THE PARTS UP ON A CAKE RACK ON MY WOOD STOVE. THEY GOT SO HOT THAT I HAD TO HANDLE THEM WITH A POT HOLDER. I REASSEMBLED THE NVG, AND IT HAS NOT MALFUNCTIONED SINCE. THAT HAS BEEN ABOUT 3 MONTHS AGO. GO FIGURE.

MY HOPE IS THAT THIS MAY HELP SOMEONE ELSE.
