Running HDMI cable from Yamaha 1600 to Toshiba DLP... All was working fine and now I get a singal loss error on the receiver

Either port could have gone bad. Mechanical stress from repeated plugging and unplugging as well as twisting pressure from the weight or angle of the cable could bend pins or even detach the connector from its internal electrical connections.


However before you jump to that conclusion you need to eliminate the more common problems first. The most common problem is that you don't have your inputs and outputs set up correctly. It is pretty common to change something by accident.


What source device(s) are you using? What input resolution from each and what output resolution to your DLP? Have you changed anything recently with regard to source devices or the resolution or type of connection you were using?


Have you tried hooking any HDMI source devices directly to the DLP using a short HDMI cable?


Do you have access to a reasonably portable alternate HDMI TV that you could try hooking up to your receiver's output -- or perhaps take the receiver to a friend's house?


Try to re-verify all of your setup settings, and then see if you can isolate which side of the cable is really having the problem here.

Thanks Bob


All good points, I haven't changed any settings or moved any cables prior to the error. I have since this was posted plugged my DVD player directly to the HDMI port on the TV and I get a green flickering screen the same as what the receiver was getting. So I am somewhat convinced that the problem is at the TV not the receiver, either way its a lose lose situation. I bought the TV from Costco so I guess Ill see if they will allow me to swap it out for another.


thanks again

Terry

I don't know how much further you want to try to diagnose this yourself, but the next step would be to set your DVD player to 480p output (the easiest HDMI signal for your TV to deal with), and try again with a direct connection. Again this should be with a short HDMI cable -- under 6 feet long.


If that WORKS, then that suggests you may have a cable problem. I know you've tried other cables, but if something was marginal about your original hookup, then it may have slipped over into not working simply because of slight changes in the mechanical fit of the plugs or even some corrosion on the pins.


If that FAILS, another thing to test is to make sure the plug -- particularly at the TV end -- is FULLY inserted STRAIGHT into the socket. The HDMI plug is just a friction fit and it is, unfortunately, quite easy for it to work loose under the weight of the cable for instance. It takes only a little for the signal to fail. The way to test this is, perhaps with the aid of a friend, to grasp the end of the cable near the socket and to hold it firmly into the socket -- pressing straight in. If that brings the signal back, then your solution may be to find some way to support the cable near that socket -- perhaps a twist tie holding it to some other cable or to the TV frame itself.


Good luck!

Alright tried all the different suggestions and no dice. I took the Toshiba 47inch 720p and they replaced it with the Toshiba 62inch 1080p. Out of pocket will cost me $100 once they credit me for the coupon that will be available from Jan 22-28 for $300 off. Brought the TV home set it up and all is working just fine (knock on wood). Thanks again Bob for all the helpful advice.
