Re: Watching a DVD under Raspian Stretch, how?

As above.
As far as I am aware, there is no Linux compatible software that supports AACS decoding (the encryption used in bluray media)

VLC can play back blurays if modified, but it still cannot decode the AACS file.

Re: Too much heating and USB port not working on Raspberry Pi Zero W

Your Pi is dead. It is only a matter of time until it will no longer boot.

Have you plugged anything into the GPIO at any point? Incorrect wiring is a common cause of killing a Pi

Re: Can I run a Raspberry-Pi 3 B+ with 5" LCD touchscreen on Rechargeable batteries?

Yes but as there are more types and sizes of "rechargeable batteries" commonly available than you have fingers and toes that "yes" may not be much use to you. Also note that there is currently no cell chemistry which can provide a battery giving 5 volts for a significant portion of its discharge cy...

How can I tell if I have the revised board ?
Since the problem has only just been diagnosed, you do not have a revised edition.
The silkscreening will probably show this information.

Re: Powering Pi from 3S lipo with LM2596 step-down converter

It is how those Lipo are made. Many wholesale manufacturers where I live stress this point.

For example, I recently purchased a 10,000mAh cell directly from the Chinese manufacturer. It came with a datasheet which claims the cell is capable of 1C (10A) but the wiring is rated for [email protected]

Those specs are odd. In one place it saysit has no storage, in another it says it has a 40Gb HDD.

Does it even boot before the battery is empty?

I cannot answer number two, but your first question is easy and documented. It does depend which model of Pi you have, but if you've got a Pi3b or Pi3b+, you can use 1.2A / 4 - other peripherals, per port. In other words, 1.2A max, shared between all ports with any one port being able to deliver tha...

Re: Yellow lightning bolt

After a quick look, that case confuses me. It has a power button, yet the power goes directly into the Pi? It also doesn't specify Pi3b+ compatibility, but I don't think thats anything to worry about. Using better quality wiring to that power switch, however its wired up, should fix the issue for you.

Re: Yellow lightning bolt

Which model Raspberry Pi are you using and which version of the power supply?

The newer Pi models use more power and there are two adaptors, one capable of 2A, suitable for a Pi2b and below (plus the Zero models) and one rated for 2.5A, recommended for the Pi3b and 3b+ models.

Re: Can i power a rpi3 and a 5” lcd from 1 power adapter?

Personally, I don't think that will help because it sounds like a component simply failed.

Anyway, the proposed solution will work, but be sure to connect the ground between Pi and screen.

Its probably the USB port itself. Are you able to connect the usb cable directly to the power rails inside?
