Dear sir,
I hope i was in U A E to help you with this problem,
This problem has nothing got to with software or whatever the dish tv guys arre telling you to do.But this problem is with the SMPS (switch mode power supply).which is inside the receiver ,U should immediately change the power supply board.Now it is only blinking dimly and stabilising after 10 to 15 minutes,gradually it will deteriorate to hours and ultimately it will completely go dead.So please change the power supply or send the box to me .I will repair it and give it to you.iam in bangalore
