Thanks for the reply. What did it cost you to rebuild the power supply? Did you do it or send it in to Roku?
I just used BBJohns' parts list in "List of parts to fix your power supply" thread in this forum and a soldering iron...
The output voltage is low, so something else is ready to fail too. I will probably install an aftermarket power supply sometime soon -- unless a component on the mother board fails before I get around to it. I keep watching the "No Power / No Component Video" thread to see what other folks learn.
