Hi all,

One of my oldest customers, engineer and friend has a Unity 4000 rx that started doing odd things a couple of weeks ago.  I haven't had time to get to his site and may not for another week or two.

It started dropping audio intermittently, with a wildly fluctuating EB and then more than intermittently and now just sits and to use his term, "chatters".  He originally checked the LNB, cable, etc, etc but nothing seemed to cure the increasing drop outs.  Now it appears to be mostly dead and I assume that the "chattering" sound that he is hearing is one or more relays closing.

Anybody ever saw a power supply in the 4000 cause something like this?  Is the PS replaceable?  Any idea on a part #?

If not a PS, then what?

Regards,
