Circuit Board help

[SparkyStu]

Hi guys, I have problems with a circuit board taken out of an all-singing and dancing front room flame effect fire. The makers told me the circuit board is likely the problem for the fire not working, but the boards are no longer available. (Great.) So, I need to fix this one. Can anybody help me (looking at the pictures) identify what is the most likely component to have died?

Seems like there is heat discoloration around toroid and the four power diodes right
next to it and large electrolytic

Tedious but consider hand drawing a schematic, then use DVM R measurements to look
for shorts at various circuit nodes. Or start with diode check on DVM, and confirm each
diode looks like a diode, fwd and rev bias with DVM diode check mode.

Check caps not shorted, always key failures causing other failures.
