Last week my TV was at fault finally after fixing it I found all the channels on my humax receiver model IR Ace II were mixed up
.
Some how I have tuned the receiver and got most of the channels . However some of the channels are not coming
It says tuning failure if I put the followinf frequencies . Like some examples :
If I put
10775 V, 27500, 3/4

10911 V, 27500, 3/4

10872 H, 27500 , 3/4

I am not able to get the channel

It says tuning failed .

I was even able to get the new channels Like Arab TV , Panorama film , AL Majd9 , Toyor El_Janah & so on. I think all the frequencies start with 10 can not found and give tunning failure . All these channels with these frequencies are not coming can you please tell me how to fix this problem

Thank you
