Recently our samsung 3D blu-ray player hdmi cable was accidentally disconnected from our av receiver. We didn't realize it until we tried to watch a dvd. As soon as we realized the problem, we reconnected the hdmi cable to the av receiver; however, we get no video and sound that fades in and out from the speakers. We tried a different hdmi cable, tested the dvd player on another tv, and also connected the dvd player directly to the tv without the av receiver and all of these tests worked so we know it's not the dvd player or the hdmi cable. In addition, we tried to use a different hdmi port on the av receiver but no luck. The tv is connected to the av receiver and we get both video and sound.
If anyone can offer any advice, it would be greatly appreciated. We are not experts, the surround sound system was set up by a professional but we have some technical knowledge.
Any help would be greatly appreciated.
Thanks.
