Macbook Pro Black Screen - Chime

MacBook Pro 15-Inch "Core i7" 2.66 Mid-2010

When you push power button

it DOES chime.
NO keyboard back light
NO image on screen
NO screen back light

This has been sitting for awhile, not sure where original hdd has gone. I had installed what i thought was the original hdd (turned out to be from an old Windows laptop)

when this was connected and turn the Macbook Pro on, the usual was happening, however out of curiosity i connected an external monitor and was greeted with a blank screen with blinking underscore

(assuming because incompatible software)

so i then took the ssd from another macbook pro i have to see if it would boot/ run normally to external screen.

With the SSD connected, the usual blank screen, no lights but then the machine will turn itself off.

if i disconnect SSD leaving no boot disc the machine will boot chime, fans run etc but will stay running.

Worth noting, i can't see any obvious corrosion around display connector, or anywhere for that matter.

I have removed RAM. I have tried different RAM. i have tried SMC & PRAM/NVRAM reset.

I cant find any info on the web about this specific scenario, unless I'm hopeless at searching.

Any info, suggestions welcome!

MacBook Pro

Go Here: If your Mac doesn't Turn On or Start Up - Apple Support

Using External Devices: Try Resetting the SMC and NVRAM, but this time, using an external keyboard. Connect an external monitor and see if you get an output.

Some Thoughts:

Do you hear the fan upon boot? Does it power on yet?

Boot into Safe Mode:

Booting into Safe Mode makes installations operate without preferences, opening it. System caches are placed aside. So, see if that works. Hold down the shift key upon boot to boot into Safe Mode. Go Here: Use safe mode to isolate issues with your Mac - Apple Support.

Use a New Charger:

Perhaps it is not getting enough charge, if any charge at all. So, use a new charger, and use a new battery. If this were me, I would use Apple brand, and none other, as it would be more trustworthy.

Use an External Speaker:

See if you hear the chime when you turn this on.

Create and then Use a USB Bootable Installer:

Create a Bootable installer for macOS --- Create High Sierra

Contact an AASP:

Go Here: Find Locations - Apple Authorized Reseller
Click: Service & Support
Enter: your location information
See: if there is an AASP nearby
Contact: an AASP that shows up, and find out more about the services that they offer to fix the iPhone
