I got in ~10 820-3330 boards with "various issues". Some had clear PCH problems, others seem to work fine but with minor issues (i.e. bad iSight camera, bad USB ports, etc). I know this model is also very affected by the PCH/GPU failure, and I want to make sure the ones I repair that "seem" to work fine are in fact OK to re-sell.
They all pass ASD, but some of them do have the tell-tale signs of eminent failure (i.e. the "blue tinted screen" when opening PhotoBooth or disabling automatic graphics switching, etc). My question is two-fold:
1. If an 820-3330 board has the "blue-tint screen" effect when opening PhotoBooth or disabling "automatic graphics switching" in System Preferences, is the board already toast?
2. What's the best/most-reliable method of determining whether a board has latent PCH/GPU issues? Should I just run FurMark for a while to see if the board shuts off/restarts or video cuts out? How long is "enough" time to run it in order to determine if a board is OK to sell?
I obviously don't want to sell a bad board (bad for business), but I also know that a lot of these 820-3330 boards are "newer" and may last a long while before having any issues. About half of them show no signs of problematic GPUs, while others do exhibit the aforementioned blue-tint issue. Thoughts?
