@julzryu the very first thing you need to let us know is if the LED indicator is flashing red. If so, count how many times it flashes and let us know. If the LED indicator flashes red, reset the TV by disconnecting the AC power cord from the TV for two minutes, then turn on the TV.
Then start with the basics by checking the items as follows:

Check the antenna (aerial)/cable connection.
Connect the TV to the AC power outlet (mains socket), and press / on the TV or remote control.

A pleasant day.
Here are pictures of the boards when I opened the back panel.
SONY LED TV
Model: KLV - 40R352C
I've tried reseating all the possible cables that I can see but still the issue persist.
Would you recommend using another power adapter with higher AMP rating?
Need more help.

@julzryu a higher amp power adapter will not make a difference.
