Using Mac Mini with 16:9 CRT Standard Def TV by RCA connection!

Hello all,

I realise that there are others who have experienced similar problems but after spending quite a bit of time searching this forum, I wasn't able to find an answer for my particular circumstance. In summary, I can't get my new Mac mini to work with my TV at all. I need to figure out where the problem might lie. Please find the specifics of my setup below.

I have a 1.42GHz Mac Mini G4 with all the possible add-ons . It actually did not come out of the box for the first three months I owned it. I finally got it out this weekend and went to purchase a DVI-Video connector. I connected it to the TV by means of an RCA to Scart cable (which I know for a fact works fine with my Powerbook and iBook) and the TV just showed a blank screen (though there was a second or two of static each time I started up, as if settings were being re-adjusted). The TV only has Scart inputs so there RCA is going to have to be the connection method. The TV is a standard def Sanyo 16:9 CRT.

To make sure the mini was working, and enable VNC access (brand new mini so hadn't been set up at all), I took it to my office (I have no other monitors here) and connected it to a normal Dell LCD monitor. It worked fine, and I set up VNC access so now I can use my powerbook to control it headless.

I brought it back home and connected it to the TV again and VNCed to it expecting to find options to re-adjust resolution, refresh rate etc. All I found was 800x600 or 640x480 and I could not change the refresh rate at all. The TV is PAL but there was no mention of PAL or NTSC options. I took the opportunity to run software update and apply all the necessary updates as well.

After some initial research, I downloaded displayconfigx. It crashes every time I try to open it... so no luck there. Then I tried another application recommended on these fora whose name escapes me now (but it started with an s and also ended with an x) and to keep a long story short, I found it very confusing and wasn't able to find a setting that made things work.

The TV works fine as a secondary display for both my powerbook G4 and iBook G3. In fact, I'm using it with my powerbook now and my powerbook switches to the right settings as soon as I plug it in! However, my powerbook's place is in my lap and this Mac mini is sitting there unused when I really want to be using it as my media center and EyeTV box!

Please help me. Is this a problem with the DVI-Video adapter. Is this a problem with the mini? Should I call Apple Support (I don't have Applecare but it was purchased three months ago)? Please help me solve this problem!

Thanks,

Phaedon

It was just a guess since your original post did not specify the type or origin of the DVI-to-Video adapter you were using. I thought you might have been using one from a source other than Apple. But it sounds like you have the right adapter.

When everything is working correctly from your iBook or PowerBook, what does Display Prefernces show as the resolution and refresh? That would be helpful info. Also, what is the display identified as? Does your PowerBook or iBook identify it with a unique name? Does the mini identify it differently? You could have a bad adapter. I wouldn't rule that out. Is there another TV at your disposal you can try the mini and adapter with?

Thank you very much for these helpful suggestions and questions!

I'm at work at the moment but I do remember the answers to most of these questions off the top of my head and will get the rest when I get home.

When everything is working fine for the PowerBook, the resolution list shows a variety of interlaced resolutions ranging from 680 x 480 to 1024 x 768. There are about five or six options. The refresh rate options are PAL 50Hz or NTSC 60Hz.

As for how it identifies the TV when connected, I have to admit I don't remember, but I believe it just identifies it as a generic TV.

The Mac mini doesn't identify it at all. I can confirm this because I tried booting it without the monitor attached and then attaching it and I also booted it with the monitor attached. In all cases, the same options for resolution were shown (1024 x 768 and 800 x 600) and refresh rate is geyed out. To me, this indicates that it is not communicating with the display at all.

I think that adapter may well be broken as it's never been tested with another display so this is the argument I'm going to make when I go back to the Apple Store this evening!

I'll keep you posted on whether the new one works or not.

Please do let me know if you think there are any other tests I should run or not.

Cheers,

Phaedon
