for coship 2300b use this bin (Coship2300B_05_15_04)then initially you will see many lines, in case that the lines traverse in vertical form and the image is black and white you will begin for intuition, but you will be able to change norm of the Sistem Setting with the button of the side will press 2 times go down to Sistem Setting then you press OK, then you press 5 times down and immediately press the side key to put your norm PAL-M, NTSC-M or PAL-G
I have a coship 2300b, and I had the same problem.
Whit this bin you can wach TV for 2 o 3 hours if the picture an sound is gone turn OF the reciver for 30 seconds and press ON with back swich, then you can wach TV for Other 2 or 3 hours.
