All lights on on modern

Hey there, woke up this morning with no internet but my TV service is working and all of the lights on the modem were on and they were bright I've never seen them that bright. I've tried unplugging and plugging back in all the cables. I've tried the troubleshooting on the app and everything. the only light that comes on now is the power light. this a bad modem possibly? Should I just exchange it
