Ok thank you my brother, Ramadan karim.
The problem is the receiver don’t power up nothing on the screen, when I plug the power cord the power board make's a small clicking sound and I tested the power output from the power board with the power cable plugged to the receiver board it reads the following: the 30v out=15v the 15v out=7v and so on but if you unplug the cable from the receiver board the out of 30v reaches 60v and so on.
At first the problem was that the tuner don’t power up the lnb (the tuner output was 7v no matter if you put 13 or 18) but if you power up the lnb from another source you can lock signal and search channels, mean by that the tuner was ok so I've tried to change the (lm317) but it didn’t work and the output of the lm317 was like 24v so I got back to the old lm317 where the output was 7v. And now I don’t know what's wrong but after I soldered the old lm317 the receiver started and when I unplugged the power and plugged again after a will it won't start, and the reading of the output of the lm317 is now 3.3v. I checked for a short circuit but I didn’t found any.
Thank you my brother in advance.
