Just posted a query about purchasing a new Dell monitor (below). This topic is how to eek out just a bit more use from the iMac.

It looks like the only problem is the screen blacking out. A few weeks ago (a month or so?) I started noticing vertical lines in the screen, but I could ignore those striations.

As I understand it, the iMac comes with a mini-Display port. However, the Thunderbolt/mini-Display port that connects the MBA to the old, 19" Dell monitor does not fit the iMac.

Will a different mini-Display port to VGA let me use the iMac with a darkened screen by ignoring the iMac and viewing the Dell?

Even better, any simple thoughts on fixing the screen? In my dreams, a simple PRAM reset or something that fixed things would be great.

The situation reminds me of getting a few more weeks out of an old iBook by opening up the innards and heating and re-flowing the solder.

If it’s the screen, rather than the video card, then the right adapter will let you use the Dell.

Pull the glass off the front, blow it out, make sure its not dusty?

The mini display is next to the FW 800 port... should be the same as MBA

Yeah, I can find the mini-display port on the back of the iMac. The cable I use for the MBA just does not feel like it fits. (Clearly, don't want to force it.)

Will (gently) try again. May have to pull the iMac completely away from the wall, rather than just tilted away.

Mine was tight, maybe rotate?

Not that much dust flew out of the case. Did manage to coax the mini-Display cable in to the iMac. Should be good for a week or two.

Cool. Did you take off the glass? Tons below the screen.

Here’s a potentially helpful troubleshooting page for iMac screen problems from iFixIt.

(I found this since my FIL’s iMac screen started having probs - haven’t gotten around to it yet though).
