Sorry to hear about the problems your having but it does sound like there is a problem in your board. I would recomend contacting a Customer Support Representative from where you purchased it.
If you got it from Newark-element14 you can call 800 463 9275 or use the Web Chat
I have logged a RTM under warrenty because my raspberry pi has just stopped working.
Mod B 512mb rev2
The voltage accoss TP1 and TP2 on the problem device is 4.04 volts (not a good start).
The voltage accoss the top of the 3v3 regulator (output) and TP2 was 2.25 volts.
The voltage accoss pin 1 and pin 5 of the connector (USB micro) was 4.40 volts.
I can tell you now, this is not a pwer supply issue because I did the same test with an old rev1 board and the voltage accoss TP1 and TP2 was 5.05 volts. I think the fuse is blown or something else in the 5 volt input cicuit has gone wrong because anthing in the circuit (as per the schematics) gets very very hot. The fuse reaches a tempature of 40 degrees C in about 10 seconds of power going through it and the 3v3 regulator (RG2) reaches 40 C in about 25 seconds.
Does anyone know what is wrong? I am going to return it anyway but it would be nice to know what my problem was.
Thanks for the tips, Jason.
I initially called Newark.com at their listed number (877-736-4835), and the guy I spoke to directed me to http://www.element14.com/community/groups/raspberry-pi. From that page I couldn't figure out how to actually contact anyone. Clicking around on this page seems to just get me back to that same 877 number.
I tried the web chat and directed the tech I got to this discussion, hoping that I could quickly establish that I had already done the troubleshooting and that my Pi is bad. As soon as I mentioned I wanted to get the thing RMA'd, immediately he told me to use the RMA and left the chat. I was hoping to get RMA approval from a live person.
So at this point I have:
- Sent a message to support (chat was offline and I used the contact form offered there instead). No response.
- Used live chat (above).
- Emailed support (no response).
- Filed an RMA, linking to this thread and asking for a warranty replacement. That was 8 days ago and I haven't received a response.
I was really hoping to avoid a phone call because I'm afraid it will become protracted and I'm convinced all I really need is an RMA under warranty (I've already done the necessary troubleshooting and even written up this nice summary of it!).
I'm getting pretty frustrated by the lack of a response. I know I'm just one among hundreds of thousands who have bought a Pi, but I still need the support my warranty should get me.
I guess I'll have to try calling them next.
Update: I called them on Friday 1/18 and the guy I spoke to said their procedure is to get me in a queue and have a support person call me back. He said that would "probably be Monday" 1/21. So far, I haven't received that call.
I can help you with getting that taken care of, I will send you a private message and get it all squared away.
Well thankfully, this story has a happy ending. I was able to get the defective Pi RMA'd without further issues once Dave stepped in.
Thank you Dave, and thank you Element14!
Apologies if this doesn't belong here but I couldn't seem to find any other way to reach out for help through the community site.
I recently received a new Raspberry Pi (my second one). The issue I'm having is that within a few minutes of booting up, the unit will unepectedly freeze (display says "unsupported signal" and the Pi stops responding to pings).
My first Pi is a model B rev 1 (256MB RAM) and this second unit I ordered (model B rev 2) was intended as an upgrade. I have a setup (power supply, Element 14 branded SD card with Raspbian Weezy installation, and an external HDD plugged into a powered USB hub) that has been working like a charm for several months. I'm using the Ethernet port for network connectivity.
I started by swapping out only the board, leaving everything else (SD card, power supply, hub with HDD) in place from my existing setup.
Here's what I've done to troubleshoot:
- Followed the instructions here on the troubleshooting wiki. Both tests (TP1 to TP2 and the Polyfuse test) reported voltages within the stated acceptable ranges.
- Booted without the USB hub (and the external HDD).
- Used another power supply (a new one that I bought from Newark along with the new rev 2 board).
- Tried another (new) class 10 SD card with the latest OpenELEC Raspberry Pi image.
Each time, I observed no changes in the behavior: the unit freezes within a few minutes of booting (even if I let it sit idle after boot).
