Mistakingly didn’t test the pie before I installed it in the Pironman 5 case. After taking it apart and returning it for a replacement I wanted to be sure that it wasn’t the case that potentially took it out as I really don’t want to brick another one.
Looking carefully at the HDMI card I noticed that one of the solder joints rubs right up against the hole for the standoff. I’m curious if this could have taken out the pie? If so, why so ridiculously sloppy for a commercially available product that is quite frankly ridiculously fidgety to put together.
I attempted to include multiple photos of what I found however it will only allow me to use one so this is the one I have. I will see if I can add the other in a comment.
It would light up but I couldn’t get video out. And before you ask yes I know it was dead I have multiple pies and I tested against multiple known good cables that once plugged into a different pie immediately powered on perfectly.
Here is a close-up of the same spot.
Do you mean the solder joints of the USB-HDMI adapter are touching the copper standoffs? If so, it is recommended that you remove the Pi5 and power it on separately to see if it can boot up and function normally.
Please provide us with a video of the Pi5 booting up when powered alone so we can confirm the status and observe how the Pi5’s status indicator LEDs behave.
Also, could you provide a close-up picture showing the contact point between the copper standoff and the solder joint on the USB-HDMI adapter when it is mounted with the standoffs?
Yes, that is what I mean. Yes, I did try that and, no it would not display an image any longer. When it first turned on there were SSD lights, they went away, within a second, maybe 2, They were replaced with what I thought might be a very faint smell of burning electronics. I’m sure you know the smell I’m talking about.
The input device recognized there was an HDMI signal of sorts… like it would switch for a moment when plugged in, but nothing else.
When I booted it only the red led on the pi 5 came on. I tore it down to bare pi and swapped out a known good Micro SD card (had to take off the known SSD) against known working cables. Trust me when I say, the pi is toast, somehow. Whether the case caused it is up in the air but I’m hoping for a way to test it so it won’t happen again. I don’t know how I would get that standoff image you want as it would be mounted but I will try a little later today to get a picture like that out of the case.
I returned the PI to Amazon thinking I was possibly shipped a bad one. I have a replacement one now. I then, had a thought about how perhaps the HDMI extender might have hosed the HDMI port (detected signal but no video out). That is when I looked at where the standoffs would sit and saw that it would have hit that solder joint.
I just don’t want to risk another 16gb model and am looking for advice on how to insulate or test the kit. Maybe a schematic so I can test voltages with a multi meter, or solder mask to cover the board or even perhaps a washer to get in the way, etc.
Okay, so I got the best picture I could out of the case with my phone. While doing so I noticed a tiny little piece of solder/metal that is jumping over a bit. I wonder if it was a tad big bigger, reaching across and my pulling it out and futzing with it caused it to break a piece off? Obviously conjecture at this point.
That said, if I test the PI beforehand, with the battery on that board, is there any risk of me testing outside of the case with just that extender board? Is it feasible for that board to hose the HDMI output of a PI? Basically I’d like to put it back together but I want to remove as much risk from the situation as possible.
Thank you for your feedback. We will implement stricter quality control for our products moving forward.
We will arrange to ship a USB-HDMI adapter to you immediately.Please contact the service@sunfounder.com to provide your detialed address.
