Night Vision MX-11769 Elbit troubleshooting tips?

[jeffl838]

Turned on a WP Elbit PVS 14 today and the tube didn't turn on. I tested by turning on the IR illum and the red IR indictor came on. Changed out the battery anyways and still no luck.

Tore the unit apart and tested the housing with another tube and it worked just fine.

Applied power directly to the tube and it still didn't turn on.

I really hope it's not the tube because I bought it used (no warranty) and is still fairly new. Any suggestions? Is there anything else I can try?

did you put the tube inside the known working housing? Possible that when you attempted to apply power directly to the tube, you didn't ground it correctly. Other possibility is, the tube took a dump and is likely shot unless you have someone replace the power unit (not cheap).

I did put the suspect tube into the known working housing. No dice unfortunately. Does anyone have a guide for replacing the PSU? Can't seem to find anything online.
