direct TV DVR is also connected through an HDMI portal and works. it is just the DVD player that I cannot get the TV to recognize. would that still be the main board?
I would REALLY doubt that situation.
When you have 3 Devices connected with HDMI and only one does not work ( you should have mentioned that to me) then I would suspect either --
A ] Your HDMI cable is not good -- Exchange that cable over to a device that does work fine. See if the other unit suddenly doesn't work. If so, your cable is bad.
B ] Your DVD player isn't good -- Take the cable from a good working unit and use it on your DVD. You know that cable is good. Does the DVD still state "Not supported"?
If so, connect that DVD player to your TV set with one of the Composite cables like this one --
Most people have extras/spares around their homes.
Or you can use a set of High Definition Component Cables like this one --
They provide a high definition picture, just like HDMI does.
In either case, you get a picture so you can check the DVD's VIDEO RESOLUTION settings in the DVD menu (Dvd must be removed from your player to access the Video resolution setting).
You want to make sure it's set for 1080i only, not 1080P
In that setup menu, you may find an HDMI on/off control. If it's off, you get no picture on the older units, a REAL NEW DVD player with CEC control....you want to turn it off.
I guess I should ask you for the Brand and Model number of your DVD, and see if you just bought it. If so, I'll see if I can get more information on it, so I can walk you through the setup procedure.
I was assuming you had the DVD connected to your TV set for a long time and it was functioning fine before.
If you have any questions, just ask
Tips are greatly appreciated !
