Flashing red and white generally means the unit failed to update. Reboot the device and try again. It may help to hardwire the device to your router to get it to update.

I have tried hardwire my device to the router over night. It still has the same issue. Any other way to hard reset it? Or should I bring it down to a shop, can they help?
Hello @Waynerbee, welcome to the Sonos Community!
I’m sorry to hear you are having issues setting up your Sonos Play:1.
Can you confirm if the light is flashing orange and white or red and white? As @schoondoggy mentioned above with the support link, there is a difference.
Flashing orange and white
The status light will flash orange and white when your Sonos product is updating.
If you’re resetting your Sonos product, the status light will flash orange and white while the reset is in process.
Flashing red and white
The Sonos product failed to update. Reboot your Sonos product and attempt to update the product again.
Have a look on our support article about how to Factory reset your Sonos product, you could also try this process while the Sonos Play:1 is hardwired to your router via an Ethernet cable.
If you are still having trouble getting it to work, I would suggest you to reach out to our Support team for some live troubleshooting. They have tools at their disposal to provide you with information and advice about your system and what it reports.
I hope this helps.
