I have a problem with my neighbour's 9865HD Nextbox. Setting up a new TV, I must've disconnected the external drive I'd installed years ago. Although the Nextbox has power, the power button is dark and has no effect. The display is also blank. The TV gets no output from the box.
I disconnected power, reconnected the drive, reconnected the power cord. No effect. I did the same while keeping the power button pressed; still no effect.
What should I do now?
