Instead the ribbon connecting the screen failed. I took it to a reputable repair shop, who told me based on their experience the failure rate on these for other display-related reasons was high enough that in their opinion I'd be throwing good money after bad. So I told them to just use mine for parts or recycle it. (It was old enough by then that the latest OS X no longer supported it, thus defeating its purpose for software development. In return I decided to simply no longer support Mac versions of software I write.)
