I once had an Apple helpline person walk me through doing 5 and it 
cured what was then a sysem video playback issue. Or was it low-grade 
audio distortion. I've forgotten.

Despite it's somewhat good behavior right this minute, it has already 
had another short tantrum of about 5 iterations.  I recall that last 
week I got over it (for a week), by the yank-plug, multi-bleat startup, 
and additionally (read somewhere on line unrelated to my specific 
malady), booting without any firewire/usb stuff plugged in.  Then all 
was well, after replugging in the outboard stuff, for this week.

But I have problems trusting that I really addressed the issue with all 
that folderol.

8 Times?

Why 8 times? That's silly.  Once. That resets the PRAM. you gain nothing
by resetting it again.

(In the old PowerPC days it was normal to do it three times. I don't
know why.)

Life is silly.  Online someone mentioned going higher than 5.  When an 
Apple Care guy helped me through some video/audio issues that I 
couldn't sort out he instructed me to do it 5 times.  I asked why and 
he said that some caches somewhere didn't clear until one had done it 5 
times.  That's my silly.

While on that topic, I did indeed revert to forcing a second, and the 
issue didn't hesitate to come back, blacking the screen during the 
initial display screen.

> Once. That resets the PRAM. you gain nothing by resetting it again.

I assume you mean one additional sound; holding it down through the 
second sound.

> (In the old PowerPC days it was normal to do it three times. I don't know why.)

Silliness, undoubtedly.

he's full of shit.

pram is reset the moment it bongs a second time. anything after that is
a total waste of time.

IIRC, the additional reset was to reset RAM on certain third-party cards
that may have been installed in the machine.

There's no reason to do any more than two in a row, AFAIK. And for most
cases, one is enough.

Try deleting this file and then rebooting:

/Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist

I'll put it in the queue for the next episode.  What is this 
PowerManagement thing?

That file stores settings like the display sleep timer, system sleep 
timer, the automatic restart on power loss setting, wake on LAN, etc. 
That file going bad is the first place I would look to solve a problem 
with display sleep. Corrupt plist files are, in my experience, the 
#1 cause of misbehaving things in OS X.

Very interesting.  If it were a corrupt plist, wouldn't Tech Tool Pro 7 
find this in a file structure test where it tests for "integrity and 
structure"?  It sure finds a lot of curious corrupted files buried in 
the library folder.

Wha other corrupt plist files have you run into that cause mayhem?

Nope. Tech Tool Pro or any other of those types of utilities don't know 
what the contents of plist files are supposed to be, and thus aren't 
going to know when the contents are wrong.
 
> Wha other corrupt plist files have you run into that cause mayhem?

Far too many to list. When any app starts to misbehave that's one of the 
first places I look. MS office apps, many Apple apps (Address Book, 
iMovie, etc), just about any app that crashes on launch, I have been 
able to fix by trashing its associated preference file(s). 

This is why reinstalling misbehaving apps or reinstalling the whole OS 
usually won't fix them; because the bad plist files that are 
really causing the problem remain behind. 

A good way to test is to log in to a different user account and see if 
the problem persists there. If it doesn't, I can predict with certainty 
that it's a bad file in my user account causing the problem; most likely 
a plist file.

Good stuff!  I'll have plists in my scope with the next such adventure. 
Thanks for the input!

Another cycle of endless sleep, trigger-awake, sleep, trigger-awake 
this morning.

Between momentary black-outs I deleted this and rebooted. I note that a 
rewake screen works for a minue, then less and within a short while 
will only stay lit for about 1.5 seconds before faux-sleep.  I say 
"faux", because I have found if I am typing or dragging a window or 
something, despite the screen being dark, my activity continues; text 
is stored, the window moves until I release the mouse, etc.

I deleted the file and rebooted--before the boot screen and start-up 
process was done it had already started it's black-screen routine.

A while back I suggested creating another account and testing 
to see if it sleeps and wakes ok on its basic settings or on very 
simple setting... Or, maybe you have a guest login option already you 
could use. As I said, this is a drag for you because you would then 
have to wait till it happened and what will you do on a login without 
all your normal facilities? Invite a beggar in perhaps to experience 
some IT for a few hours in return for a report on this particular 
matter.

Is there a way to disable the iMac screen altogether and just plug in 
an external? If so, this might rule out whether the screen itself has 
something hairbrained about it, reacting to something inappropriately?

Yes; I have a secondary account for such things.

Precisely the difficulty.  If it only happened while running a specific 
app, it would be much easier.

I've pondered that: My wife has a mini-mac with an a monitor that 
connects via hdmi.  I find myself totally stunned that my older iMac 
had an hdmi port but inexplicably my late-2009 iMac doesn't seem to 
have one.

You must be confusing the connectors. The first Mac with a built-in HDMI
port was the Mac Mini introduced in June 2010. There is not yet any iMac
with a built-in HDMI port, just Mac Minis, the current Mac Pro, and all
MacBook Pros with Retina Display.

Macs going back to Late 2008 or 2009 (varies betewen models) have Mini
DisplayPort, for which third party adapters are available to connect to
HDMI. Your Late 2009 iMac will have this connector. (Mini DisplayPort
was merged into Thunderbolt starting with 2011 models. The Thunderbolt
connector is identical and compatible with Mini DisplayPort adapters and
cables.)

Prior to Mini DisplayPort, Intel Macs had either a full DVI connector or
a Mini-DVI connector. (The original MacBook Air had Micro-DVI, unique to
that model.) DVI can be adapted to HDMI. Mini-DVI is now old enough that
the adapters are getting harder to find, but there was a Mini-DVI to DVI
adapter, allowing HDMI via a chained adapter.

Going back into the PowerPC era, there were a few models with Mini-DVI,
some with VGA, but a lot more with Mini-VGA, DVI or Apple Display
Connector (which can be adapted to DVI). The VGA variants are not
compatible with HDMI (analog vs digital).

I'm sure you're right, I bought an adaptor of some kind and had been 
using it so long I forgot.  It's been in the garage for a while.  I 
just bought another online.  So I can likely still go out to the garage 
and test this thing again, provided it screws up again.

It's pestered me three times today.  And then, inexplicably stopped.

It has no DVI/VGA output ports?

My late-2009 iMac has these ports:

	http://grab.by/FZdA

After reconsidering, I feel quite I have an hdmi cable with an adaptor 
on it that lets it connect via the Mini DisplayPort.  Likely in the 
garage somewhere with lots of other abandoned stuff.

Curiously yesterday and today I sorted through 3 packing boxes full of 
a snarl of cables.  I wound them, put a tie on various clots of it, 
then into zip-lock bags so that everything doesn't crossbreed in there. 
 I have a bag each for coax, ethernet, telephone wires, AV-related 
wires and switchers, phone lines, phono lines, camera-related cables, 
two kinds of fire wire cables, two kinds of usb cables, then another 
bag of mini-phone, mini-phone stereo, phone to phono, usb to female 
usb, etc.

A large box of scsi, appletalk, DIN, and all kinds of other crapp, 
dial-up modems, slower usb and firewire routers and all kinds of muck 
from yesteryear--bound for goodwill. I also through a bag of 20+ guitar 
cables, the curly wire kind, in there too.

I can't believe I was holding that adaptor in my hand and packed it up 
real neatly just yesterday.

It is easy to forget all ones stuff! <g>

You can also connect by DVI or VGA depending on your external monitor, 
older ones likely have at least VGA and the cables for those are ten a 
penny, you will likely have one... but you need an mini to VGA or mini 
to DVI for this. This means you have to have separate connection to 
speakers, but in your case,it is to test for sleeping...

Wrong.  I found this picture online somewhere but the Mini-DVI port 
shown is not actually on my iMac.  I have a completely different video 
output port; this one is called a Mini-Display port.

It actually looks like this:

So another set-back.  Now two adaptors, one still on the way, both of 
them for a different plug type.
