I have a Mitsubishi WD-65737 DLP TV. All tree HDMI ports seemed to have quit working. The odd thing is when I plug in an HDMI Device, It finds the device on the correct HDMI port it is plugged into, however it only shows a blue screen. No Video or Audio. Is this mean the main board needs replaced? or is it the DVI Cable that is attached to this board.

This might be configuration problem. Some TV Audio and AUX Ports we have to manually select from remote. Please check the configuration settings or else please refer the TV manual for Audio settings.
Hope soon you will rectify the problem.,
Bye...

try installing manufacturers Drivers for your video card... You're probably using the "default" drivers.. Might fix it to get the current ..

Do I have to also connect a Audio Cable set with the HDMI or DVI Cable?
Yes, Audio is still separate.
Are the HDMI and DVI ports Bi-Directional?
It goes one-way, Out from the source (DVD Players / some Game Consoles / Sat Receivers), In on the receiving end (Recorders / TV / Projectors).
A Receiver is perfect for your set-up. All Equipments that broadcasts audio/video signals goes into it, then from it goes to whatever Projector / TV you have.

i know this sounds stupid, but have you "toggled" or "played" with the HDMI cables? are they the same manufacturer? HDMI channel connections are very fickle. If just one connection is not exactly correct, they go to a limp, no go status. Since they run at such a minimal voltage, i can't see them "blowing" the outputs on the devices.however....if your cable has a serial type output for video only, I would connect the hdmi convertor to it and see if it works.

either your cable or your dvd player. Have you tried it on another tv to make sure its working?
