Sony dz950 DVD player brief white light and no power

Hi, I have a Sony DZ950 that suddenly became non-functioning. It could be because my house had a power tripped recently.

When I tried to turn on the DVD, the white light at the bottom of the DVD screen shows a white light for about half a second and fades out. It won’t power on so no error message and even the welcome message “Hello” is not showing. The DVD player just turned off as soon as the button is released.

I tried to open it up but see no obvious damage on all the fuses. AC power input is fine when measured with an ammeter. However, 12V and 5V output doesn’t seem to work. Can someone please guide how to pinpoint the exact issue from here?

Appreciate any help. Thanks in advance!
