    hi...I have a Sony Bravia KLV-40S200A (8 years old) and a Panasonic Blu -Ray player about 1 year old. I have an HDMI cable connecting the 2. My blu-ray has internet access and I have Netflix. I have been accessing Netflix and watching movies for a full year and then all of a sudden, nothing works. I can't access the internet/Netflix nor can I watch movies. I have 2 HDMI cables. I tried them both with the blu-ray player and nothing. I checked my cables with my computer and both work fine and when I connect my computer to the TV..no problems. I then checked my blu-ray player to another tv in the house...checked it with both HDMI cables and it worked fine. So it's gotta be the TV. But all of a sudden? I've read different forums...have unplugged the TV and unplugged the blu-ray...I've reset the TV using the up arrow and power off on the TV but nothing works. I also checked to see if there were any new drivers for download/upgrade but nothing there either. Any clues, suggestions, ideas?? Thanks!!!

First, HDMI is not a perfect hook-up solution. Cable box connections via HDMI are notorious for being problematic. The best thing you can do is contact Samsung and get the latest firmware for your TV.
Samsung Customer Care: 1-800-Samsung (1-800-726-7864). If this does not resolve the issue, connect the cable box using Component cables instead of the HDMI. Component cables are HD also. I hope this was of some assistance.

Pioneer vsx-5231 not pairing with Phillips bdp-2175 smart bluray player

have you tried to connect the Philips direct to the TV's hdmi?

Could be the resolution on the bluray is set to 1080p which may be out of range for the receiver or even the TV for that matter. If you can reset the output resolution of the bluray to 480p first, just to establish a picture then try 720P which all HD tv's and receivers can handle.

I did a quick search and could not find the resolution reset procedure for this unit. Other units will reset if you press and hold 2 or more buttons together.

No picture from Blu-ray

If the TV works fine with other sources the problem is the HDMI output is not enabled on the BD player.
Most BD players do not output both HDMI and composite formats simultaneously. Check to make sure the HDMI output is selected on the BD player and the TV. This information is in the manuals, read the book.

I would like to hook up my components without having to turn on the receiver to watch tv from DVR or Cable if possible. I have Scientific Atlanta Explorer 8300 HD Cable DVR w/HDMI out, Samsung TV w/HDMI ,...

You should not lose any picture quality from the DVD player. I am currently having the similar setup with PS3 as the Blu-ray DVD player with HDMI and a Samsung DVD as regular player with component cable to a Samsung LCD TV. Remember the quality on Blu-ray is better than normal DVD so don't expect more than what it is.

No sound

I had the same problem on 3/21/09...I found it was the PS3 settings. I had to go into the visual settings (not sound) and change the linear sound to optic digital...but I also had to purchase a digital optical cable...plug everything into your tv instead of the receiver and then hook up the digital optical cable from your tv to the receiver. A it will work and b it is a better sound quality than that of the HDMI cable.
