I have been having a lot of problems with my H25-100 re-booting and sometimes displaying a blank white screen. The re-boots come in the middle of the night and happen from 3-5 times a week. I callled tHe CSR and explained all of this to them and they said they had to roll a truck and have someone come out and check the dish alignment. and possibly replace the receiver. The tech arrived on time and the first thing he did was check signal strength. Signal strength was good ( I could have told him that). I told him the H25 was the only one of my 6 receivers that had the problem. He said he didn't have one on the truck (I could have an H21, NOT) or he would have to go to the office and see if they had one there as none of the other trucks had one either. If the office didn't have one he would have to get one from Scottsdale and come back tomorrow. This is not be a big problem for myself, but because of lack of planning, he will be wasting at least two to three hous of time that could be put to better use. I'm not sure why the CSR didn't put in the notes for the service call that an H25 might need to be swapped out and he could have either had one on the truck or rescheduled the call for a latter time when he had one avaialble. This is just another example of the inefficienceies of the DTV CSR/installer/repair process. Ok, enough complaining for now. Now I can wait for the UPS man to deliver my 2 new HR34s soemtine today (on the truck , out for delivery). If this tech has to come back tomorrow, boy will he be surprised when he sees the HR34, right next to the H25 he has to replace.
