Last week, I suddenly had a problem with my DIsh VIP 722..it had powered down..and I had difficulty getting it to power back up. When it did finally power back up...my Sanyo DP50740 Plasma TV showed "No Signal" from the receiver. Everything had been working fine previously.
I checked the other HDMI ports, and the DRV player and the Roku were showing up on their respective ports. I then traded the Dish receiver to a different port. Still no signal...yet the device moved to it's old port had a signal.
I then traded cables...and still had no signal.
The receiver eventually powered down..so then I called Dish, and they sent out a replacement receiver..and a Tech installed it yesterday...and I still have no signal on the receiver...yet the ports all appear to be working properly.
The TV is still under warranty..but am clueless on how to explain the problem...this really makes no sense.
The component outputs are working...which is the temporary step I've take to be able to watch tv.
Can anyone tell me what's going on??
