Has anyone repaired their AM21? My HR44 started rebooting, showing the Hello starting up screen, then switching to the Almost There screen and then turning off and back on loop. I got the HR44 replaced a month ago. Well this week the same thing started happening again. I called AT&T and they scheduled a service call. While waiting, I began reading forums, etc. and finally decided to just unplug all of the DirecTV equipment (HR44 and AM21) and start over. I plugged the HR44 in and it booted and I had TV. I did a red button reset twice and each time the HR44 started up correctly. I then plugged in the AM21 and did the reset. All I got was the looping as mentioned above. I did a couple more resets with the AM21 attached and still looping. I unplugged the AM21 from the HR44, did the reset on the HR44 and it came back up correctly. The blue light on the AM21 was on. So now I'm wondering about a repair. I opened the AM21 and there are 17 capacitors inside. None appeared to be leaking and none had bulges. I have ordered all of the capacitors and intend on replacing all of them. Has anyone attempted this? Any success? Anything else to look for or replace? BTW, I cut the cable tie in the attached photo so I could get the #'s off the capacitor. It didn't break from heat decay.
