Hi All. I have a 2009 Mac Pro 4,1 that won't boot. Power light comes on, but black screen. Have tried the obvious, safe start, zap PRAM, SMC reset; also tried a new graphics card, but no go. At this point it's beyond my expertise.

Does anyone know a NON-Apple-certified repair shop in NYC? it has to be NON-Apple-certified, I've checked, because the computer is so old that they will have to use salvage parts, e.g. if it's the logic board, which is quite likely. Thanks...

He runs a YouTube channel about repairing computers and can do so even if its replacing soldered on components. Seems to do good work, but I have no personal experience with him or his shop.

I have watched a lot of videos on his YT channel, seems legit to me! Have seen him fixe some pretty weird and small stuff that broke in macbooks and also uncover previous bad repair jobs from other repair shops :p

ps: have not seen yet a mac pro 4,1(5,1) being diagnosed on his channel, I would call/write and ask him and maybe we see your mac pro getting fixed by him in a future video:cool:

He doesn't touch Mac Pros. I asked him personally.

I haven't used this place personally, but they said they would work on Mac Pros:

Buy a replacement backplane on eBay and replace it yourself, a 2009 backplane sometimes can be found for less than $75 $50. It's an afternoon job, one hour for a skilled person, and somewhat easy to do.
