Loud pop no power / burnt board

I plugged in Vizeo TV and heard a loud pop. The TV now won’t power on. I opened the back up and discovered a burn mark on the back of the electric board, so I think I’ve identified the failed component but I’m out of my depth from there. Not sure what it is or how to replace it. It’s the black thing connected to the heat dissipator

Hi @newbie99

It is a bridge rectifier and it converts your 220V AC to DC voltage. You will need to desolder it form the board in order to change it.

You may also need to unscrew it from the heatsink to remove it completely.

The replacement is quite inexpensive. Just make sure you buy a similar rectifier with the same voltage tolerance. You should be able to search for it by the label on the component.

You should also check the fuse, in case it blew too!
