Hi everybody
I have an unknown problem in my SRT4400 receiver. From one month ago the channels with frequency more than 11900 on Hotbird don't have signal but on Nilesat and Telstar12 there isn't any problem.I changed my switch,Lnb setting and also upgraded its software but this problem has been remained.if it is posible please help me.
