Ok. There is an auto roll option in the 227t bin. Make sure it's off. You'll find it in the screen after entering the secondary pin. Then add the codes. Put both lines in the appropriate spots (00 and 01). You should be good then. From the sounds of your problem, the auto roll is on. I've got a wicked hangover this morning, you?
make sure u are on those channels 7000 and up,or those channnles starting with letter K.because all the other channels are saying waiting for picture or black screen......
