My 2006 iMac displays, via adaptor , on an old TV. My current 2008 iMac does not. Advice?

My 2006 iMac/El Capitan 2006 iMac displays, via adaptor , on an old TV. My current 2008 iMac does not. Advice?
 
The adaptor successfully plugged into the 2006 Mini port fails in the 2008 Mini port.
 
Both iMacs/miniDVI plug into my old TV's s-vid port. I dont recall if I tried the TV's RCA (component?) port.
Does the 2006's successful external display imply anything important?

>combo of
(mini DVI to D-SUB adaptor) + (D-SUB to Component adaptor) + Component cables to TV.

Are you advising using miniDVI AND D-sub adaptor AND component adaptor AND RCA cable, ALL AT SAME TIME ON SAME LINE to old TV?

I might have success with 2008 iMac and a new HDMI TV but its manual warns of humidity-caused fire. My TV room is narrow, has two floor-level windows , is several hundred yards in two directions from a river and summer brings so much humidity that the TV occasionally needs warming for a clear pic.

At this point of time, I would like to suggest you look into the back of your TV to see what kind of input ports are available. Mini DVi to S-video might not be supported by 2008 iMacs.
If you are lucky to have a TV with HDMI input, just buy a new mini-DVI (male) to HDMI (male) cable, or a combination of mini DVI (male) to HDMI (female) adaptor + HDMI cable.
If your TV does not have HDMI input, maybe it's time to buy a newer model TV. They are cheap now, look much sharper than the non-HDMI one.

I said its a fire risk.

Buy fire insurance, perhaps?

I provided the available TV ports but then you ask that I provide them.
I tell you about fire risk and you advise insurance.
Im disappointed that you have no realistic advice. Can you recommend a source for realistic advice?

I think we just can't understand why you would spend on stupid adapters in chains when getting a new cheap TV *with* HDMI is the solution of all your problem.

You speak about fire risk with a TV because of humidity. This is absurd, unless your house gets into 90% humidity rate which is, obviously, a problem not for the TV, but for your whole house. Get a dehumidifier ASAP because this is not good neither for your house nor for yourself to live in such high humidity.

Of course the manual explicitly says there is a fire risk. Just like every electronics that exists on this planet that work with electricity when not properly used. Every manufacturer of electronics in the world will have this in their instruction manual. This is a standard clause for anything that works with electricity that exonerates manufacturers in case of misusing their products. We call that lawyers.

And yes, we recommend you to get a fire insurance, just like everybody should have on this planet.

>adapters in chains

somebody here ,not me, recommended them. You would know that if you focused your mind.

If you had focused your mind, you would have read that my humidity is limited to my TV room and only during a few times of high summer humidity. There is no big, continuing problem. Youre emotionally overgeneralizing.

My iMac manual has no fire warning. The HDMI TV is flat panel ,unlike my current tube TV. Its microprocessors , in athin panel TV, would be a foot away from open summer windows. Thats a unique problem ,not shared with my other electronics, eg, audio system. Yes, companies must legally protect themselves from people who dont wear shoes while using a motorized lawn mower and cut off their toes. But its not obvious that such absurdity can be generalized to my situation. Are you claiming that a few days of high humidity is safe for a flat panel TV a short distance from windows.

We?! Do you have a little man in your head?
 
What type of adapter are you using that works on the iMac 2006, but not iMac 2008? Is it an Apple-branded adapter or one from a third-party?

Apple did make a video adapter that was Mini-DVI on one end and the other had both S-Video and Composite RCA. The model number was M9319G/A. It is no longer produced, however.

No name on white adaptor.
Amazon records only my HDMI (not s-vid/RCA ) adaptor purchase. WalMart has no record of any Mini-DVI purchase (but your number and the photo is right). Good try. Those two companies are the ones I typically use.
 
The official Apple M9319G/A adapter will work with the following iMac models: iMac (Early 2008) iMac (Mid 2007) iMac (Late 2006) iMac (Early 2006). So if that is an Apple adapter, it should work with your 2008 iMac.

Looking at some third-party adapters, they mention only the various 2006/2007 Mac models (iMac, MacBook, etc). The official Apple M9319G/A adapter also will not work with 2009 Mac models, even though the official Apple DVI and VGA adapters do.

So it could very well be that if your adapter is a third-party model, it doesn't work with a 2008 iMac. You could try to find the official Apple M9319G/A adapter like on eBay or such.

My iMac is early 2008. My adaptor has no name on it. I found an Ebay adaptor claimed as Apple M9319G/A. It looks slightly different from mine. I asked the seller for proof its Apple. Thanks.
 
They were never made by Apple. It was purchased from the Apple store years ago. Apple licensed a third party manufacturer to produce these adapters.
==========

Ebay seller sent the above to me. Its contra your claim of an official Apple adaptor.
Walmart has an adaptor that looks like mine, not like the Ebay adaptor from above seller. Walmart claims Apple made it. Im lost amidst these contradictions.
 
That eBay seller is incorrect since there are plenty of retail hits for an Apple Mini-DVI to Video Adapter Model M9319G/A. Apple no longer makes that adapter, so none of the retail outlets have it in stock, but clearly it did exist at one time. Heck, I actually have seen that exact Apple adapter at an old job of mine where all the software devs used MacBook Pros going back to the first Intel models.

And here is a Google cache of the official Apple webpage on their adapters and what Mac models they worked with, including M9319G/A: https://mediawiki.middlebury.edu/wikis/LIS/images/4/4d/Monitor_and_display_adapter_table.pdf
