The resistor R15 has a burnt out lead and has been burnt out and it will need to be replaced. (shown in red circle)
I think that the colour bands on the resistor are Yellow - Purple - Orange - Gold.
If this is correct the resistor value is 47K Ohms and it has a tolerance value of 5%. It is a bit hard to tell from the image but it is either a 0.5W power rated or a 1W power rated resistor.
Replace it with a 1W rated just to be safe.
The MOV (shown as MOV2 on the board - and in green box) next to the resistor may also be damaged or it may be OK and has just caught the “blast” from the resistor burning out.
There should be some markings on the MOV which can be deciphered to indicate its’ value etc.
Be sure not to touch the marking with your fingers as sometimes they rub straight off.
It should also be replaced just to be sure.
The two cable (black wire and white wire) connectors (blue arrows) will have to be disconnected from the board and inspected in case they have been damaged as well

There may be other less obvious problems that may have to be found by testing with an Ohmmeter and then on a ''live'' circuit with a Voltmeter.

If you don’t know how to use a DMM and since lethal voltages are involved when testing for voltages, contact an electronics repair service and ask for a quote.
