Update firmware - factory firmware has quite a few USB-PD problems, which the newer firmwares fix. See the [https://github.com/Ralim/IronOS/blob/master/Documentation/Flashing.md#pinecil-pine64 update documentation on GitHub]
* Check cable with another device

  - Using PinePower or some other non-grounded PSU?
|Internal problem with power
    - This is likely to be a "lack of grounding" problem. When using Pinepower, you can unplug the figure-8 AC cable plug (on the back), rotate it 180 degrees and plug it back in - this tends to remedy the problem [https://github.com/Ralim/IronOS/issues/975 (insights)]

  - The FUSB302 might have gotten damaged and shorted an internal power rail
|Out-of-date firmware
    - Fix is to use a hot air gun to remove the FUSB from the board. You can leave the iron without the FUSB302 IC, or you can find and buy a replacement.

    - Without the FUSB IC present, you will lose USB-PD compatibility - the Type-C jack will not power your Pinecil with a C-to-C cable, or from a PD-capable PSU with attached type-C cable (laptop PSUs)

    - You will still have USB QC support without the FUSB IC, and all the other features will keep working!

== Pinecil tip heats up too much, starts to glow and [REDACTED] ==
|This is likely to be a "lack of grounding" problem. When using Pinepower, you can unplug the figure-8 AC cable plug (on the back), rotate it 180 degrees and plug it back in - this tends to remedy the problem [https://github.com/Ralim/IronOS/issues/975 (insights)]
  If you don't press the + button after plugging power in, does it start glowing?
|-
  - If it heats up as soon as you connect power (without button presses), then it's likely a FET failure - the FET can be replaced. by using a hot air station or a soldering iron.
| Doesn't power on after applying 24V to the barrel jack  
  - If it only heats up after pressing the button, this is likely to be bad soldering of the thermocouple amplifier IC caused such behaviour. Resoldering the thermocouple amplifier shoudl fix this problem.
|Damaged USB chip
  You will want to replace the tip after it's heated up to the point of glowing, as the surface coating is likely to have gotten compromised.
