HDMI died - received replacement - annoying buzz gone!
Powered on my 622 receiver early this week and noticed there was no video. The receiver is connected to my HDTV via a HDMI cable. I powered up my other devices (hooked up via component cables) and noticed they were working fine…even my cable and over-the-air broadcast television inputs were working. I attempted to recover the receiver by performing a soft and then hard reboot. This did not correct the problem since I had still has blank screen.:down
I then swapped out the HDMI cable with a spare to no avail. The 622 is running in single user mode and I have TV2 (composite cables) running to my DVD recorder. I turned on my DVD recorder-->switched to the appropriate input on my HDTV-->selected the appropriate input on my DVD recorder and viola! All of the 622’s tuner and DVR functions are working perfectly when displayed on TV2.
I then swapped out my 622 with my 942 dual-tuner HD receiver. The HDMI output worked perfectly on the 942 using existing HDMI cable. Plugged in the 622 and experienced the same trouble with HDMI. I then connected the 622 using component cables, but that too had failed (blank screen).
OTHER ISSUES: I’ve had various problems (blank screens, audio sync, trailing video effects (MPEG-4 HD LIL) with this receiver, but most were related to receive software and/or transponder encoder issues. However, I have experienced a persistent, and rather annoying, electronic buzzing when skipping forward/backward through recordings. Likewise, the tuner would also make an annoying electronic buzzing sound when local over-the-air channels experience borderline signal levels (i.e. when the OTA channels start to break-up the receiver will buzz). The receiver appeared to have operated normally for the most part and, since I never had any of these problems with my 942, I assumed they could be corrected with software. Ref:

Anyway, I received a replacement receiver from E* yesterday. I hooked it up late last night and it works like a champ; all previously noted problems (that were blamed on software) have been corrected. Both boxes are running L356 and the only obvious difference is the dead 622 was using version B motherboard whereas the replacement 622 is using a version D motherboard. :up
