Re: Make pwr & act LED visible externally

you could remove the existing LEDs, add some wire, and run them to outside your case, but that will be tricky to solder and would void any warranty.
a simpler approach is to drill a small hole in the case if you can.

Re: USB C power port fell off

I would contact wherever you bought it and begin a warranty claim, that's not been soldered properly.

There are alternative power methods available, if you decide not to go via the supplier for a replacement.

Re: Cannot delete partition SD card. Back to original SD.

I know you don't want to continue the discussion, but the minimum card size is 8GB. a 4GB does not have enough space to install a 5GB+ Operating system. It doesn't solve the issue, but it might explain why you are seeing the 'out of space' error. moderators don't have time to approve every single po...

I believe the idea behind including an on screen keyboard by default was so that users without a keyboard on hand could setup Raspbian via a touchscreen. naturally, it's easy to apt-get install one, provided you have a physical keyboard on hand to type the install commands. do you see the catch 22? ...

Re: Cannot delete partition SD card. Back to original SD.

"almost new" means nothing, unfortunately.
certain actions can incorrectly set the write protect bit prematurely or the card may even come with the bit set fresh out of the packaging (I've personally experienced this)

Re: Accidental 12V Overvoltage and smoke

So for now, I can remove the TVs and just short the two leads that connect to the tvs? As drgeoff has said, merely remove the TVS diode (after identifying it), it is normally not bridged. it's job is to create a short circuit upon failure conditions, which will prevent power from going to the Pi (o...

I've pushed a Pi4b below 10°C while in use. just because you can though, doesn't mean it's beneficial. the extra energy required to keep it that cold far outweighs the benefits. it'll run fine at 60°C, get it to 50 if that makes you happy, but ultimately there is no actual need to unless you're hol...

Re: Accidental 12V Overvoltage and smoke

if the TVS diode died, then I would expect it to get hot - it's a short circuit after all.

I'm not sure what the green LED signifies.

Re: Accidental 12V Overvoltage and smoke

Which Pi, you may have only killed the TVS diode (No guarantees there). Removing the diode should allow the Pi to boot if so, but do not make the same mistake again without replacing the diode or the Pi will be dead for sure.

Depending on what the display requires by way of voltage and current it is potentially possible to use a single HDMI cable to get power and HDMI to a remote display. One can inject power at one end, extract it at the other, using additional adapters or by hacking the boards at both ends. It might b...

Cardboard from a cereal pack or plastic from a milk container, both of these are about the right thickness to friction hold the cable like the original plastic clamp does.
