lxkev Posted November 16, 2012 Share Posted November 16, 2012 Hello, Advice needed. Martin Roboscan 918 power ups fine. When the lamp sticks a loud humming sound comes from the back off the unit near the transformer... anyone have any ideas of what might be causing this?

greenalien Posted November 17, 2012 Share Posted November 17, 2012 If the noise starts when the lamp strikes, it's probably the ballast. Link to comment Share on other sites More sharing options...
Richard CSL Posted November 17, 2012 Share Posted November 17, 2012 the transformer laminates are making the noise, we used to have a similar problem with transformers years ago, solution dent the laminates with a hammer, this often used to work.
