Dynex TV Will Not Power On

I’m currently trying to diagnose my TV not powering and I do not have a manual.

Here are a few notes:

-Screen is black (does not power on). Sound does not work as well.

-Performed the “flashlight test” and did not see any "no signal" or anything dimly lit to indicate it is a backlighting issue.

Opened up the back of the TV and:

-Backlighting board seems fine. I havent taken it out and it is covered by metal but I can see the coils and they do not looked burned.

-Initially heard a "popping" sound when TV broke. However, I can not find any swollen transformers on any of the boards.

-Standby light in the front of the TV is On when plugged in, this light is red.

-Power On/Off Switch works. Standby light turns blue when the power button is turned on and stays blue.

I could use some help determining what the issue is and what replacement parts I need to buy. Thank you for your assistance.
