Hi Maz,
I had the same thing with a 2700 receiver getting 5-7 channels. Provided it isn't a deffective box and has a card in it, give this trick a try.
1st, If your running a dish 500, take the coax lead from 119w off the switch21 and run it to the receiver sat input and check the 119 signal strength box. (you can reconnect the dish 500 switch when finished)
Do a reset with the remote exactly in this order starting/watching a preview channel.
MENU + 6 + 3 + INFO + Left arrow + Right arrow, You should see a screen says something like "memory dump", if not, repeat, if yes then press the TV/Video button and you see it then ask you to unplug power for a minuete, do that then re-plug, turn on, go to signal meter, select transpounder 11 (must be 11) and turn the 2800 off with the remote or front power button. Do NOT interupt the reciever for 1 hour. Leave the power pluged in and coax connected as it takes the update. Turn ON after 1 hour and Wala!All channels back..
You can then reconnect the switch 21 if you run two sats.
Enjoy,
JimmyJam
