Help getting started with Roku devices, including setup, connecting your device to your TV, linking a Roku device to your account at my.roku.com/link, adding channels, subscribing to services, and more.
Hello, I purchased a Roku Ultra 4640X used to add to the other ones I already have in the house including another Ultra. This one however on setup works fine but if power is lost either when unplugging or if power goes out it loses all memory of settings, channels, login, network ect and has to be set up like a new STB. Is this anything anyone else had had an issue with? FYI I need this particular box as the SPD/IF is required to output sound to my non HDMI HD TV ( DVI-I input only).
I've had a 4640 since they first came out, and have never had an issue disconnecting or losing power and having to set it back up. I haven't had it shut down in quite a while, when I moved it from the bedroom to the family room. Been a couple of power outages as well, and it's never happened. I don't believe they have an internal battery to retain settings, like a CMOS battery on a motherboard, but maybe they do. Perhaps Tanner or Danny can confirm if there's an internal battery.

Most likely the internal flash memory chipset has been corrupted. You can try to factory reset the device and then do a system update. These are programmable "memory" chips.
They could be toast, however.
Best way to protect against this, though not a fail-safe is using a surge protector and maintaining cool operating conditions. The purpose of the chipset is to retain settings when no power is supplied (similar to a battery or USB flash drive/stick). It is a mini hard drive.
