I've got a TiVo Roamio that froze up the other night with a black screen only slowly showing the overlays and not consistently. I unplugged it and now I'm stuck with no video output and alternating blue and green lights. There is no red light, unlike the other video I've seen uploaded that is usually a bad drive. I've uploaded a video of my flashing lights to YouTube: https://youtu.be/yRg_pGWonSY

Has anyone seen this issue before? It still has an original drive so I suspect it's that, but I'm hoping to confirm in case it's the power supply or motherboard instead.
