I could only get into the simple ones, like Space Invaders, Apple Panic and Raster Blaster Pin Ball.
Last month I "got into" a Sony PlayStation 3 -- a box more modern than that required for Space Invaders, but one considered retro nowadays, I suppose. (Therefore I'm not OT posting this in the Nostalgia section, right? That's my story and I'm sticking to it!)
I'm not a gamer, but a certain five-year-old in my life is.
When the PS3 woke up one day with its status LED showing the dreaded Yellow Light Of Death (YLOD), something had to be done! But some internet research led me to an unwelcome conclusion. It was time to expand my troubleshooting expertise in a new direction:
BGA reflow!
In the time-honored tradition of reflow hobbyists, I did the work in the kitchen using cooking appliances (plus a heat gun). The PS3 motherboard is actually beautiful and fascinating. And of course the
Cell processor is a whole study in itself. But I had to shed my admiration and replace it with pure aggression. I baked the %$#!*ing ^%#! out of those BGA's,
absolutely flamed them with extended, point-blank heat gun set on high.
And the board had been pre-heated with the electric skillet you see.
Even so, I never saw the BGA's budge or "settle" as I expected to happen when (if) the solder balls melted. Perhaps at the factory the BGA's were glued to the board prior to the original reflow -- I dunno. I
do know it was stressful not knowing when to stop! Eventually my courage failed and I quit. The tops of the BGA's were hot enough to melt solder. I could only hope the bottoms were, too.
I guess a thermocouple is the proper way to manage. But with only gut instinct (and luck) I seem to have cheated the yellow light of Death!
