Hello everyone, I am trying to find out a problem with my washing machine control module, but I have no multimeters nor any of the electronic know-how that most here have so I have been trying to do this by theory study alone.
Sadly I reached a dead end now where I can't still understand what is going on with the component so I am here hoping that some amazing guru will manage to find out what exactly is going on.
Details:
Washing machine released in 2005
Model: Samsung Q1044
The control panel number: MFS-Q1044-00
No history of previous problems, this was the first and only one so far.
The following video shows exactly what the problem is whenever I plug it to the wall until I unplug it:

Pressing any button does nothing.
I have opened the machine and I found out that it had a cockroach infestation and I am assuming that one of them caused a short circuit on the PCB that blew 2 tracks because I found one all roasted near the blown tracks, as the following image shows:

The 3 point solder there belongs to a M10LZ47 5-J (or 5-i, not sure now) which can be seen better from the view above, it's the small one screwed to the heatsink:

I have already have the tracks repaired but still the problem persists, nothing changed.
I have also looked for any component that could be busted or show any signs of fault but none was to be found.
Buying a replacement is not an option since I already looked for it for a long time and everyone says it's not made anymore and I don't have the money to just buy a new machine and since this one was expensive at the time I would really want to get it fixed and working again.
This is a very weird problem because most of the times, for me, when an electronic component goes bad then the system simply doesn't work, period. With this one it still works, kinda, and the power goes straight to the motor for some reason as if the control module chip is runing in blank mode, like it was wiped clean during a short circuit or something like that.
If anyone wants better pictures or more details I will gladly post them. I really hope someone here can help me out, I am out of options and washing by hand during winter has been quite harsh.
