if you go to the Menus and Settings and more info at each recvr, it will tell you what that recvr model (and other info) is ... no need to take anything apart to find out.I am not sure now- without pulling them out to look. Two of them are away from home- mobile use now. I do know they use the white remotes if that helps. Used to be I could go on Directv's website and look at my equipment- but now that they have combined with ATT, I have searched everywhere and can't find my equipment listing- All I get with searching equipment is my cell phones listings. I'm also mildly concerned that he replaced the correct receiver and not one of my others. How would I know without my equipment list? I guess if one of the others stopped working- I'd know in a heartbeat. I have one that hardly ever gets used.
Also, ever since I spoke with Directv, and ordered my free upgrade- I have received two 800 number voicemails telling me I am eligible for 50% discount from Directv and to call back on the same number (800) that I received the voicemails from to be able to claim my discount. The voice had a strong Indian accent as well both times. I suspect this is a scam of some sort- that DTV would never call me- all communications have been by text or e-mail up until now. Do you have an opinion?
Combining with att had nothing to do with most of what your experiencing.
You Can still find your Equipment info online, just get into your account, it will tell you.
