D6220 will no longer power up

[JeffreyJames]

After briefly powering off my modem/ router I can no longer get it to power up.
Any suggestions?

I should say that the power is on. I’ve tried a few power points. When I activate the little power on/off button there is a momentary flash of light on the “dashboard”. I assume this to be the power indicator light.

Would pushing the reset pin help?

Sounds like it is toast. If it does not stay powered up the unit is done.
