First of all apologize for my English.
A disaster similar to the one described in this thread has happened to me:
https://www.raspberrypi.org/forums/view ... 28&t=70903
With some important differences:
- The charger has apparently nothing happened to it.
- The TV has been damaged through HDMI
Step to summarize what happened.
A USB to microUSB cable that apparently had no damage and has been used for a long time to charge phones and other devices, caused the Raspberry pi to "explode" and through the HDMI cable (which now also does not work) has damaged the TV.
It seems that the USB cables have caused a short circuit which, when plugging in the USB, has caused a flash and subsequent burning smell.
The part of the microUSB connector and some other electronic component near the HDMI have been completely burned, and the case also a bit.
The TV was connected to the Raspberry via HDMI, although it was turned off, it has also been affected and has not started anymore.
I still have the doubt if the problem has been the cable itself, or a USB sound card that I wanted to try (newly purchased), but I doubt it, and tomorrow I will leave doubts trying it with an old PC.
