Hi my name is Roety,
I can help you with your issue ,
Why don't you simply run the cable box and DVD stereo outputs direct to the receiver. Thats what most people do. TVs do not passthrough stereo signal very well do to DHCP compliance requirements .

There are several fixes for this problem.

1) You can unplug the TV for a few minutes and try again.

2) You can turn off the TV then hold the Power button down for at least 10 seconds (resets the processor)

3) Go to the settings menu, select factory reset.


Good luck

I had a similar problem with a Mac Mini.  The problem was caused by a mix-matched resolution (the Mac tries to use 75Hz refresh rate, TV expects 60Hz).  The best solution I found was to remote into the Mac (I used LogMeIn.com) and change the resolution on the Mac from a remote computer until the image appears on screen.
Process: 1) Connect Mac to a normal monitor and install the LogMeIn server (or other VNC type application) 2) Connect the Mac to the TV 3) Connect to LogMeIn from another computer (preferrably one where you can see the TV) 4) Go to Applications / System Preferences / Display 5) Change the resolution to your TVs native resolution, and change the refresh rate to 60Hz

timberline did you reset the tv to factory setting this may solve the problem

are you using an hdmi cable or the red blue and green cables that came with the xbox? if using the original cables there is a switch on them that sets it to HD or standard. hope that helps

I just tried a Sony code for my Westinghouse tv after reading other sites, and it worked. The code that worked for me was 10000

My 42" Westinghouse HDMI inputs just stopped working. I thought it was the TW Explorer 4250HDC issue so I got a new one from TW. Still said no signal from HDMI. So, I shut the TV down and pulled the power cord out of the back. I waited a few seconds and reconnected the pwr cord. The TV "re-booted" so to say and now the HDMI inputs work. I think TVTEK has the right idea that it is firmware/software related. In the mean time, you might want to give that a try.
