Is this soldered controller repairable by an amateur? (infosec.pub)

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?

Any chance of identifying the burned-out part on the left? If not, I'd leave this to professionals (repair cafe, maybe). A throw blanket works at mains voltage, so errors might have serious consequences.

Apart from that, you don't know what caused that burn, so that cause might still be around, and instantly burn down any repaired board again.

So my recommendation is: NO.

Thanks. It seems wasteful to throw it away but I'm working on my loss aversion 😉 and technically the blanket is still a blanket, just less warm
