Is this soldered controller repairable by an amateur? (lemmy.zip)

I have a controller for an electric throw blanket that I would like to repair, but I have no experience soldering on boards

You can see at bottom left a yellow box and a resistor. Something has burnt out in this area, and likely both will need to be replaced at a minimum

I would also need help identifying parts. The yellow box is embossed 'Tenta' and has printed on the side 'TC MEX/TENTAMKP 0.1 uf 275VAC' with some other markings obscured or damaged

Is this an achievable project?

Thanks, if that is the pad below the resistor I assume that component is also damaged and would likely replace it as well. I'll do some searching and reading on the capacitor, is a U1 chip something generic or will it have markings to indicate specs?

A bit of context for you:

U1 is a reference for the PCB designer and assembler (if soldered by hand).

The information you need to find a replacement is the etched text on top of the IC (Integrated circuit, a.k.a "chip").

If you're able to read that, put the whole thing into Google or Octopart or your electronics component supplier of choice (Mouser, DigiKey, Farnell, etc). and you should find the IC you need.

Thanks!
