I have a 2 year old Mistubishi DLP WD52725. I bought a new Sony STR-DA5200ES AV receiver and installed it yesterday. Got the Sony mainly for the HDMI connectivity. Unfortunately the TV won't accept signal through HDMI! Accepts it through component just fine. Any suggestions? If HDMI won't work I can return Sony for much cheaper receiver.

You don't mention what source devices you are using. Some source devices are actually the problem here since it is the source device that has the primary task of setting up the connection. For example many cable TV boxes have a shoddy implementation of the copy protection portion of HDMI which makes it impossible for them to set up the connection unless they are DIRECTLY connected to a TV.

In any event, the first thing to do is to try connecting your HDMI sources directly to the TV to verify that its HDMI input is working and that you have properly selected/enabled it.

If that works, see if there is a way to get you Sony to generate HDMI video output independent of any source video -- perhaps a Sony-generated menu or test pattern or background screen or some such. You may need to set the output resolution to 480p for this. Then see if you can get your TV to accept that signal. 480p puts the least demands on the connection so it is useful for testing.

One common cause of HDMI failures is cabling. Use a flashlight to check the plugs and sockets at both ends looking for any signs of pin damage. Make sure the plugs are FULLY inserted STRAIGHT into the sockets and not being pulled, even a little bit by, say, the weight of the cable.

If you find you can get the connection working at low video resolution but not at high resolution, then you likely need to upgrade/shorten your HDMI cable.

If you get video, but it is strange in some way -- shocking pink or ghastly green for example -- then that's just an indication that there is a mismatch in settings between the receiver and the TV. The usual culprit here is the "data format": RGB or YCbCr.

Also check the appropriate receiver thread in the Amps/Receivers/Processors forum here for any suggestions.

Thanks. The installer was working on the system when this all happened so all I know so afr is what he said, "HDMI is not very standard so one never knows if components are compatible until they are connected. " This gives me some thing to look at.

You may want to serach/post to the "Mitsubishi XX725" thread as well. It's a good thread with a lot of info.

I have a 52725 myself and my HDMI has never worked properly (either with my Panny S97 DVD player or my Series 3 Tivo) but this is an audio problem and not a total lack of picture. For both of my HDMI devices all I did was plug them in and make sure the device (not the TV) had the HDMI output enabled. Also, I assume you are looking at the MONLINK input on the TV?
