I picked up a used Openbox S10 months ago and any time I tried to watch an HD channel or move the USALS motor the box would reboot. I ordered a new power supply and tried it again and same problem. I then found with a voltmeter that the power supply was dropping voltage when trying to move the motor causing the box to reboot. Then friends at another forum found that the ic regulator chip in the power supply SD4841P is underrated for the box. They found that a SD4844p chip is better suited. So I went ahead and ordered the chip for about 6$ shipped and soldered it into my original power supply in place of the old chip. I am happy to say that this repair fixed the rebooting problem completely and now the box works perfectly! It took many months to figure this out but now the problem is solved. Hope this helps anyone with a S10 rebooting problem!
