I've had my Dyson for 3.5 years now and the power button stopped working. The trigger is not responsive. I checked with Dyson repair services and to fix the trigger they ask for $130. Dyson itself is so expensive (I bought mine for $500), they use defective parts and to top that to repair it is an additional $130...  I know there are so many videos how to fix that but any tips and tricks would be great.
