Recently went on a service call in which the cust had a 625, 311 and a 322. On the 625 she was missing the hallmark channel but every now and then she said it worked. So I checked the receiver health , the signal coming into the box , inspected the cable run , and a few other things and found no apparent reason for the trouble. She had a .2 so I changed out the lnb there was also a 33 switch so I changed it out changed out all diplexers , ground block and connectors. Still didn't fix the problem so I did a hard reset on all the receivers and sent a hit out once it was done it was working. It has been about 20 days or so and it started doing it again any thoughts on the cause ?ay e re rune all the cable , change the 33 to a 44 or run a 3rd leg to do away with the switch or ra the receiver ?
