Hi, please bare with me guys, I’m in the UK have this piece of beauty equipment I’m trying to fix, I’ve got it down to this PCB board that is blowing the glass fuse every time power is applied. I’ve tried to have it repaired by a local company, but they said they couldn’t, but they believe it to be the transformer component at fault. I’m looking for someone in the UK to help me with this and if it can be repaired. Im an electrician, so knowledge when it comes to this is very basic, please bare with. Thanks.

 

If you have a multimeter you can do some basic testing to check the transformer.
It looks like it has a built in rectifier circuit.
Can you take pictures of the track side..

 

Hopefully these are ok

 

Appears to be a sealed unit AC and DC out,
May have to replace it with a small wall wart , either external or open one up and jury rig it onto the board.

i don’t want to sound like an idiot, but I’m totally lost on what you said. My expertise is lost on this, I’m looking for help and someone to fix it.

I might be able to help from a distance of 4,000 miles!
Can you at least remove parts from the board and jury rig something in if necessary?
As an electrician you should have some inkling of the components such as power supply, albeit that it is contained inside a module.
Possible fix, Wall-Wart: power supply that goes in a wall socket.

yes I have an understanding of how the power supply works. I was hoping to be able to just remove it and replace, but yes, I’d happily have a plug socket transformer that powers it. I’m not 100% that’s the problem, but the cooling fan in the machine stopped, so I think it overheated. So I’m hoping it’s the transformer, if it isn’t, I’ll be stuck for sure.

 

If you can unsolder the P.S. you can use a AC cord with Croc clips to power up and test the voltage.
The tricky part is removing it, solder sucker or dry wick helps.
BTW, I have a UK electricians ticket, but went into Industrial electronics, soon after.

 

Ok,

Ok I’ll buy a tool see if I can remove the part and test it. I hope that is the problem. Ahhh ok, I’m still just an electrician

 

Yes it's a sealed unit, unsolder the transformer and replace it with a phone charger you can solder the lead to the pcb.
