Stuck on a white screen

I got the macbook yesterday, and it was working fine. I went to get an SSD and a ram upgrade at a local hardware store. I got the SSD and the salesman tried installing numerous ram modules to see what worked. Repeatedly swapping them till one combo of a 1067 and a 1600 MHz worked. As i used it and saw it was indeed functional, it crashed immediately.

It refused to boot-up since then even after swapping the original 2GB kit back in.

Or so I thought. Turns out the chime arrives 57 seconds after the button is pressed. Till then the device stays on a black screen, no chime with the HDD and DVD drive spinning. After the chime arrives, the sound starts breaking? and then I’m presented with the white screen. I’ve already tried to access multiple recovery modes but all of them result in a white screen. Even SMC reset and PRAM reset did nothing to help. I’m not sure what to do as of now. Currently I’m creating a High Sierra Install Disk using transmac.(Dont have another mac) hoping it will boot off it.


Please advise

First you need the correct RAM for your system: 1066 MHz PC3-8500 DDR3

But before you can go beyond 4 GB you need to update the systems firmware (EFI) from what the system had for the older OS-X’s. So you need to get back to the original RAM config and then you need to upgrade your OS first to a newer one. I strongly you don’t go beyond Sierra (macOS 10.12.x) as Apple has issues with SATA based systems.

You’ll need to create an OS installer disk to boot your system from. Either an external FireWire drive or optical drive. Depending on your exact OS (firmware) installed presently you might have bootable USB drive support.

Here’s the steps to make the needed installer How to create a bootable macOS Sierra installer drive

FYI the max this series can support for RAM:

  • 2.26 GHz - 8 GB
  • 2.4 GHz - 16 GB

I tried that, somehow inserting a bootable USB key sped up the whole 57 second chime. Now the issue is the white screen still. It looks like it's just the backlight and the display doesn't function. As connecting it to an external display and hitting the mirror keys made me see the recovery menu. As for the ram, the current sticks are the default 1067 2GB kit that came with it.

The internal white screen and you have a working external display is telling me your internal display got damaged or is the wrong one for the system. Did someone replace it?

@danj The 2.26 will only take 8 GB of RAM

@mayer - I jumped too soon ;-{ Your right!

The screen was working right before the sales idiot furiously swapped ram. Here's my theory on what happened. Repeatedly switching the ram and turning it off using the battery ribbon cable along with running an incorrect ram set ended up corrupting something somewhere in the boot. Now with no output the guy panics and pulls at the display cable hoping for some display not knowing how to take it off and ends up damaging it. After that the rest is history. I'm not sure on the service history of it as I got it off the equivalent of craigslist. But I'm sure other than the ancient HDD, nothing was wrong with the laptop. I've given the laptop to a technician that's hopefully seen more apple devices. At this point, it chimes normally, lights up white, caps lock key works in recovery after a minute or two, connecting a display when caps lock works results in a recovery display(has not booted normally, assuming corrupt macOS install). Will update on what this new tech says.
