0) My Pandora doesn't turn on anymore at all.

1) Connect the DC-in cable. Does the Pandora turn on?
a) Yes → Fixed. Your battery charge was too low.
b) Give it an additional 1h. Does it go on then?
b1) Yes → Fixed. Your battery level was reduced to a critical level. It was revived.
b2) Use it for light applications while it charges.
b3) Use overclocking/heavy applications only when it charged another 1-2h, then your battery should have a stable enough charge to withstand peak levels again.

2) Try the USB-power-in. Same steps as in 1.

3) Try USB-power-in and DC-in at the same time. Same steps as in 1.

4) Take out the battery.
a) Connect only DC-in. Boots → Your Pandora works. Your battery has become unreliable/dead. Purchase a new battery. As of 2022-12 [https://dragonbox.de/en/accessories-for-pandora-pyra/pandora-replacement-battery.html batteries are still sold].
b) Connect only USB-power-in. Boots → Your Pandora works. Your battery has become unreliable/dead. Purchase a new battery.

For now charge via USB. Consider servicing the DC-in plug/circuitry.

5) Check your USB and DC power plugs with a voltmeter. Maybe the do not provide the proper voltage and/or current.

6) Your Pandora may fail due to a corrupted bootloader. In that state neither the status-LEDs nor the screen get turned on.

a) Try this: [https://pyra-handheld.com/boards/threads/openpandora-type-1002-doesnt-turn-on-anymore-what-to-check-how-to-repair.99796/post-1712104 Incomplete info] here.
