EDIT: Thanks everyone, Problem solved.
Any simple suggestions on replacing C1 in this circuit?
What value capacitor(?) it is? Or likely to be?
C1 selected as possible fault on basis of possible magic smoke residues.
Board is from an artificial Christmas tree with optic fibre tipps in the foliage.
The green LEDs will now only flash for <0.5 seconds very very infrequently.
I have a multimeter and a soldering iron.
Suggestions for hashtags?
@RueNahcMohr @skua And no transformer or anything that could provide galvanic insulation.
But it says Pri: 240V Sec: 12V 😨
@bastelwombat @RueNahcMohr @skua I'd agree I think the circuit is safe enough, the label is on the wall wart transformer that is feeding 12Vac to the PCB.
I don't think C1 is the issue, although the soldering on C1, R1 and U1 all look none to clever.
My bet would be that U1 (looks like a voltage regulator for U2) has blown but without part numbers for U1 or U2 you've little chance.
Bet the tree kills wifi for miles around when running.

Thanks folks.
Your inputs are much appreciated.
I'll look further at replacing the lights with a project like the one below.

Fibreoptic Christmas Tree Upgrade: We've had one of those fibre optic Christmas trees for some years. The base contains a 12V halogen reflector bulb, and a coloured disk driven by a motor is placed between the bulb and the base of the tree. The bulb and the motor are powered by a 12V…
