I'm not sure if you found any of the advice useful as you seem to have stopped responding. If you still need help I think I have the answer you're looking for.
First you do not need to see the screen or even have it work to factory reset your device. Use this link and follow the directions within to access your Bootloader screen, from there it's all Volume buttons and power buttons. The phone will vibrate letting you know it is powering off or on.

Additional advice:
Watch the video a couple of times. You will need to gauge the time it takes before the Samsung logo appears so you'll know when to let go of the buttons. So is it a 1, 2 count or a 1 hound dog, 2 hound dog....
Next you will need to know how many down clicks it is to factory reset. Is it 4 Vol down or 5 Vol down clicks.
Then you will need to know if it up or down to confirm that Yes you want to factory reset your device.
My final advice would be to do it twice.
