4 My Sony bravia KD-49XF8505 will no longer boot up
I have a Sony Bravia KD-49XF8505 that no longer wants to boot up.
While booting up the TV, my father pressed the mute button (sound), then the TV suddenly showed lines for a moment, then completely shut down. After this incident, we have not been able to turn on the TV, also the light at the bottom of the TV does not turn on anymore.
I checked the adapter and it shows the "normal" voltage, as written on the back of the adapter.
In addition to testing the adapter, I also plugged my cell phone into the usb port on the mainboard, and it appears to be providing power, as I can charge my cell phone with it.
I also checked to see if any capacitors had blown by chance, but I don't see anything about that right away.
Does anyone have any idea what could be wrong? I have already turned the TV completely off and on several times. Also pressed the power button several times when it is not connected to the wall outlet.
I myself am a software development student, so I have practically no understanding of this.
My native language is not English, so sorry for the possible typos

EDIT:
- Here are a few pictures of capacitors that I don't know if they are still any good (the first 2 images are the same capacitor)

- @oldturkey03 Is this the fuze you're talking about? It still works, tested it with a multimeter

@landervanlaer just to make sure I understand you correctly. The Power LED does not turn on. Your TV shows "no sign of life"? Post another good picture of the part of the board where your power adapter connects to. There should be a fuse around the connector.

@oldturkey03 Yup, draws power (bcs usb port works), but no sign of life

@landervanlaer checked for a fuse? They are usually labelled with the letter "F" followed by however many digits.

@oldturkey03 I have uploaded an image in COMMENTS section on the "question". I also added some pictures of some capacitors

@landervanlaer caps look okay. You got power going to the fuse. Power plugged in. meter to VDC and Red probe to right contact, Black probe to ground? Got proper voltage? Now do the same with the opposite contact on the fuse.
