The first Tech I spoke with was obviously running off his script. Fine, whatever; I have no problem with that until protocol becomes a hinderance.
I jumped through the hoops of shutting down, then resetting the PMU (Shift+Control+Option+Power for 2 sec) and PRAM (Option+Command+P+R; let the startup chime sound twice). Obviously, no effect.
Then he said that since I have third-party RAM, I'd have to remove it myself or at a service center. At which point I thanked him and ended the call. No further progress possible there.
I called back immediately, and got a Technician who actually seemed to care.
One thing Tech #1 said: after repair, machines are put through a 24 hour hardware test. I explained to Tech #2 that this machine was my livelyhood, and I was concerned I'd send it to be serviced just like before (maybe having just the screen replaced), only to have it returned to me still broken; even after their intensive testing. That got his attention.
He looked through the detailed notes from the repair, and mumbled (among many other things) something about "board". I asked him, "logic or inverter"? He seemed impress/appreciative that I knew what he was talking about. He said he doubted the logic board, and that it could be the inverter board. Also mentioned that they don't replace individual inverter boards; they'd replace "everything from the [screen] hinge up".
He got a Product Specialist in on the call. Described the problem to him: this recurrance gets worse with a longer duration of use. Because of this, the Specialist speculated that it could be the fault of some overworked video hardware... like the graphics chip... which he said is integrated with the logic board. *sigh*
He wrapped the call putting instructions to the repair techs in the case file to pay special attention to the video hardware during repair; then he issued a dispatch and shipped a box. I have greater expectations for this time through than I did for the first servicing. Hopefully Apple doesn't trample all over my trust again... But expectations and hope is where disapointment comes from. ;-)
I'm glad to hear you finally got someone with a brain. It's pretty obvious that the problem is something besides the screen at this point and that they need to be diagnosing hardware upstream from it.
