Ampower K02P133.01 TV Power Supply With Crispy Diodes and Mosfet

[RukyCon]

So i got this power supply from a Samsung TV i'm fixing and it appears the issue with it is the power supply due to it having at least 5 blown parts (maybe more) and a few blown PCB traces.
Here is the list of all of the blown parts PCB numbers...
QI831 (unknown)
DI819 (ER206)
DI821 (need to check)
R839 (SMD) (unknown)
Q826 (SMD) (unknown)

Q1832 might also be blown, it's part number is K3115
I also posted photos of the damage so people can tell me if it's worth fixing.
Thanks.

To me it might not be if this board has multiple layers and has burn the trace apart
This is the big unknown

Here is what I would do is to clean the burn up parts of this board and see how badly it is burnt and how deep the damage is I would scrape the burnt spots unit you see the board color again and if you traces real deep in the board

If you do see traces deep down in board I would not waste my time trying to repair this board

This is my two cents worth on what I see in your photos

I hope this helps
