Chosen Solution
I am trying to help my daughter withe her MacBook Pro. (A1229, 2.4 GHz, 2 GB RAM, serial ends with QX94, running 10.9.5) I replaced the HDD about six months ago, and it’s been fine, until a couple of days ago. She told me the display was black. Well, I thought I would get it back here and try a different monitor, and maybe reset the PRAM, but it seemed to me that it wasn’t booting. I could hear the optical drive if I put a disk in it, and the status light was on solid. I shut it down, and restarted by holding down the power button for about ten seconds, when it gave a loud, long beep and booted up. So I shut it down again and the same thing happens. It won’t boot normally and there is no chime. I’ve tried switching out the RAM, I’ve reset the SMC. Now it won’t boot at all, although the status light is on. Does this sound like a bad logic board?
Sounds like NVIDIA failure. If this answer is acceptable please remember to return and mark it.
Ya sounds like mother board the 661 number is an American part number for the board you can google part number maybe find a cheap one on Line or if have an apple authorized repair center near they can do an exchange with Apple for new board as long as no signs of physical damage ( liquid spill) usually 3 to $400 if liquid damage just find one on eBay and replace yourself or buy part and pay shop to install for you. But most of time it’s cheap to buy used Mac then repairing it. I do Apple repairs as a living and I always recommend buying new machines over doing a board unless can find cheap one on line.
