Just got a Raspberry Pi4B, I have tried all night to get this to work and have had no luck. Both the red and green LED indicators are both on, not blinking. I have followed all troubleshooting advice I have seen (new NOOBS, etched Raspbian, recovery.bin) and cannot get it to output anything to HDMI or even get the green LED to begin blinking. Plugging in has never caused the green lights to blink, regardless of whether or not anything else is inserted. Wired devices such as keyboards and mice don't power up when plugged in (no leds in keyboard for instance). Recovery.bin did not cause the green LED to flicker. Did my Pi brick in transport or something?

This is not a problem covered by The Boot Problems Sticky
I suggest you try removing the SD Card - where the green LED should blink 4 times alternating with long solid green.
If not you probably have a hardware problem.
