    OK, Im running a MAcbook pro latest OSX all updates etc...

    In the past I have been able to plug in the adapter (DVI to TV) to the DVI and run on end of an RCA cable out of it to the RCA video in on any tv.

    I would normally just hit f7 and the display would be seen on the tv. I would never have to press the detect display feature.

    The problem is now I cant get a picture on the tv what so ever. I have tried the detect display feature, changed resolutions, multiple tvs and cables and no luck.

    Now when i connect to an external computer monitor using the other DVI adapter everything is fine on the external monitor. f7 works fine etc...

    I believe the problem started when I hooked up the external computer monitor. It seems some setting has changed that will only recognize the the computer monitor. And the other adapter DVI to tv doesnt seem to be recognized or at least the pictures isnt sent to the tv...

    I don't think its the DVI to to tv adapter having a problem as it's newer..never been abused or anything like that... Im very confused and frustrated any help would be appreciated.

    Thanks for the suggestion. No luck. I get the tv to flash for a second and then a black screen on the tv...this is very strange

    Short of reinstalling macosx is there another way to reset things other then what was mentioned above. This is driving me crazy. I need this feature working for my presentations as sometimes I only have access to a tv...not a projector.
