Giandel inverter question

So this little board is a very important part of the inverter and does a lot of work for such a small thing....

Unit is dead right now and all in bits, this is the best picture of U1
I removed R85 shortly after putting up photo of it the solder joint wasn't just dry the joint was nonexistent on the top side of the board the bottom had good soldered joint though but one legend on the top side of the board ran to a large capacitor C23 this was completely unsoldered. other side of the resistor ran to the burnt out board. The resistor (R85) looks to be 1Watt so replacing with a bigger 2Watt resistor

I'm wondering if this resistor is what caused the board to self destruct....

Thanks for your time and help BUD I do appreciate it.
