Thanks,
Yes I have now got the VU+ up working again after replacing the C807 capacitor and an AOZ1021Ai voltage regulator ( which had a small crater in it
It was not easy to find the voltage regulator but after some searching I found them on Alixepress ( Shanghai), They sold in batches of 30 so now I have spares for a long time
The capacitor is relatively easy to replace but to desolder /solder the surface mounted voltage regulator is not for "faint hearted" if you don’t have it as profession.
