[QUOTE="DragonSat, post: 732402, member: 363210"] Hello Ralph, I have a strange problem with my D9234. The Reciever wont lock, but the signal is good, tested with a meter and another box. Reading all these problems with the PSU's in these I swapped with a known good PSU and it locked up no problem. So great the problem is the PSU. Now here is where it get tricky. All voltages are good. Purple carried +30, White +19, Grey +5 (HI) to make the white go to +19. Orange is 0v (Indicating PSU good) yet it dont work. If I use just the LNB power wires from another PSU it comes back in to lock. So the problem is definatly in the LNB power supply section of the PSU board, maybe dirty supplies to the front end reciever parts, or LNB power. Also if you go to the installer enu, the AFC is always wandering, indicating a problem with the incoming frequency, or demodulation of it. Have you seen this before? I am thinking a cap somewhere, but not the usual C9 (Which has already been changed by someone as the solder is fresh. Paul. [/QUOTE]
