My soldering station stopped working. I love this soldering station, so I opened it up to see whats going on inside. The transformer contacts had come loose, so I tightened them and VIOLA! all good.
But not longer after it stopped again and this time I couldnt fix it. Using my multimeter I tested for voltage on the circuit board, nothing. So I concluded the board was bad and ordered an after-market one from ebay.
Once the board arrived I set to work on swapping them out. The pictures of this are below.
The embarrassing part is, after the swap it still was not working. So I decided to do a little more investigation. I found that there was no voltage after the transformer AND before it. So it turns out the actual power cable was faulty, once I replaced this all worked again. Sheesh! I left the new circuit board in there as I couldnt be bothered putting back the old one. Ah well, at least now I have a spare board!

Hi
I found your article interesting since I also have a Hako 936 and the station does not light up.I am going to replace the power cable as you did and hope it works.
Thanks for the tip and lets hope that it works.
