This problem happened 1 day last week, then cleared up, then happened again last night, and has cleared up this morning. While watching a program, the green light on the front of CW700 goes out, & the receiver re-boots, all by itself. Then it comes back on for a few seconds, then the green light goes out & it re-boots. This goes on and on, for hours, if I let it (I end up turning the receiver off). I've tried turning the CW700 off and on from the back, but it just keeps re-booting continuously. Then the next day it's fine again. Does anyone know what causes this, and how to correct it?

I am watching Dish, sats 110 & 119.
