Glad I could help. Your English is very good, but did you learn it off old Poirot films..Thank you so much my good man. I will stroll to my local tech guru guy and have him give it a go
Orn,
No need for a photo; The part that failed was the component slightly left of the centre of your photo. Gold/yellow ring round the writing with 470163 on the top.
Ashley charged £50 + postage, sight unseen, to fix it. Very happy with that. The bit is probably 50cents, but he knew how to find and fix it. I didn't.
Apart from that, I converted the fixed torch to a Euro version with a conversion kit from Welders Warehouse. Very good idea! That was 14 yrs ago. So likely the bits are available much cheaper now.
Edit: I think Dennis Aspö might have been talking about big caps on the output of a transformer welder, rather than the PCB.
Thank you, yes Poirot and Monty PythonGlad I could help. Your English is very good, but did you learn it off old Poirot films..
