Opened for replacing faulty capacitors of the power supply.

  • Hi, I own Syncmaster 740n, I turns on/off but I can’t see any image (black sreen). I plug VGA cable to monitor. I turn in on – nothing, black screen. It should show ‘Check signal cable’ image (http://www.orionimages.com/images/faq2_1.jpg), bu it doesn’t. I can’t even go to monitors menu.. Any ideas what might be wrong?

      If you have experience repairing electronics, you can try to open it and check the capacitors of the power supply. You can see in the images posted, that some of them are worn, leaking from top or bottom, or just have a bumped top cap. Replace them with same specs and dimensions new parts and it should work again.
