Hi and welcome to JustAnswer,
Thank you for the question and your patience. Should you still need assistance for information purposes only...
Initially, it appears to be a glitch or the "booting" gets stuck.
A review; were the specific steps in the link below followed?

I have tried this, I found those steps in the manual. It turns the screen completely black. If I don't hit the straight button, the screen just says Main On.
Expert:  Louie replied 1 year ago.
I understand.
A first try; consider a firmware update (if have not been done and if applicable). Please see the link below.

This would serve as both an attempt of a fix and as a test by process of elimination.
A non-corrective RESET would be indicative of an internal hardware issue (most likely) or a firmware concern (least likely).

Tried the USB method with no luck. Still have the frozen "Main On" message.

Could the power plug be failing?
Expert:  Louie replied 1 year ago.
Sorry but no; if it were a power plug issue, then the Yamaha would not even power up at all.
All of the above would point/confirm an internal hardware issue.
I realize that the above information may perhaps be not what was expected. Unfortunately, there is no quick-n-easy fix and neither is there a workaround; sorry for having to be the bearer of bad news.

Thank you Louie. I will be taking it in to a service center. I appreciate your help, at least we ruled out software issues:)
Expert:  Louie replied 1 year ago.
Appreciate your kind understanding.
Internal repairs are needed.
And again; sorry for having to be the bearer of bad news.
Good luck and thank you too for the opportunity to be able to share the information.
