Here are some images from the [https://elektrotanya.com/yamaha_p-115b_p-115wh_p-45b.pdf/download.html|Yamaha P45B service manual] that may help. I couldn’t find the manual for a P45 so hopefully this will be close enough to still be of some help. Be patient when going to download the manual as it takes a bit of time to go from ''processing'' to ''download'' after you have passed the security check and then clicked on Go to Download.
The images show what to test for and where when the power is connected but the keyboard doesn’t turn on.

There are full schematics in the manual do if there is no power at the DM board then the schematics will help to find out why.
