sorry to say but your receiver might be fryed.......
there is two things you can try.......
follow the instructions the way I wrote them down if possible print this out.....
at the same time you turn the power on from the front then quickly turn it off from the back.....wait for 3 minutes then turn back from back do not touch the front power...this should power on by itself..after 1 or 2 minuets....then you do the following
First right down your sats settings.....do factory default this should clear up all the garbage if you had not done this before...reload the factory bin then the latest bin, re-scan your Sats, let the keyz roll leave in channel 200 if possible and enjoy your receiver & tv again.
I usually do factory Default every 2 months this keeps the receiver clean of old bin's or files...
Best of Luck on your Quest !!! Bless are doe's that get if for freeeeee....
P.S. NEXT TIME POST IN THE GENERAL FTA DISCUSSION
