Looks like you may have the same problem as several other people posting in http://www.raspberrypi.org/phpBB3/viewt ... 28&t=20657.

My advice would be to ask the supplier (RS?) for a replacement.

On further reflection, I'm not sure that you realise that you need a Linux distribution specifically geared to the RPi. Perhaps a look at http://www.raspberrypi.org/downloads would also be in order.

Wait, this might sound like a stupid question, but do I need to program the SD card with Linux before I connect the Raspberry Pi to the monitor? Would this affect the signal going from the Pi to the monitor? And does anyone know the easiest program of Linux which I can put onto the SD card? Oh, and...

Have you worked through http://elinux.org/R-Pi_Troubleshooting?

Unplug everything from the USB ports and boot it again. What happens?

drgeoff

Which operating system (OS) is supposed to be on the SD card? Did you buy the SD card with the OS already installed or did you put the OS on it yourself?

What have you got plugged in to the USB port(s)?

If you type on the keyboard, do any characters appear on the screen?

[quote="jjggag"Its very annoying because apart from the static/snowy image, I also get buzzing (sound).[/quote]
How are you hearing the buzzing sound? From the TV loudspeaker, from the power supply, from the hard disk, ...?

A better solution would be to use a 6xAA multi-block pack to make 9v and since one Ni-MH AA is approximately 3000mAh you have a total of 18000mAh to play with. :) I don't think you do. If one cell gives you 3000mAh at 1.2v then six of them in series will give you 3000mAh at 7.2v, not 18000mAh. You ...

This is beginning to look like a problem with the soldering of the BGA SoC to the PCB. Although baking may effect a cure, I would be concerned about the long term reliability of such a "repair".

I'm having a shocking time just trying to mount the image on an SD card. I'm working on a Macbook Pro via Disk Utility and when I attempt to restore the file using the image from SqueezePlug 5, ticking the box that says Erase Destination, I get the following error message: "Could not validate sourc...

The green LED is the equivalent of the Hard Disk activity light that is (or was at one time) common on the front panel of PCs. When lit it signifies that the SD card is being accessed. Initially it was labelled 'OK' but was changed on later boards to 'Act'. The change was only to the label; there wa...

In the sixties, when Wireless World was the Fount of All Knowledge, I remember an ongoing discussion (can't remember the protagonists). The underlying theory was that one should design a layout using waveguide principles. I don't recall that specific discussion but I seem to remember the name "Ivor...

My understanding is that all 512Mbyte RPis have Issue 2 boards and http://www.raspberrypi.org/archives/1929 indicates that although D14 is still present on those boards, it is connected slightly differently so as not to cause the HDMI-CEC problem. The above understanding is based only on what I have...

Later firmwares and distros are much less prone to sticking/missing keys than earlier ones. So a lot depends on exactly what versions you are comparing.

drgeoff

My understanding is that the acknowledged (by people in or close to the Foundation) USB problems are not caused by the SMSC USB/LAN chip. They arise from the USB part of the Broadcomm SoC. The design (hardware logic and software driver) of that part was bought in from a third party.

Hi, thanks for your quick response. My HDMI->VGA adapter is an active one. I really don't understand what is happening, the adapter is ok, I've tested it using a Samsung monitor connected to a Toshiba laptop's HDMI port through the adapter and it worked fine. Also I've testes the RCA output using a...

drgeoff

I am not sure of your exact problem, but not all HDMI -> VGA adapters are the same is my understanding. Some are just simple wiring that passes the signal directly to the monitor and just adapts the connector basically. I believe this means that the computer has to be putting out a signal that is c...

while running the resistance rose to around 25 ohms I'm guessing you tried to measure the resistance while current was running through the device, this is impossible! A resistance measuring device (multimeter) drives a know current trough the resistor (device under test) and then measures the volta...

There are really only three possibilities: 1. Not enough power for the RPis. 2. SD cards don't have the Operating Systems written properly. 3. Faulty RPis. But It is very unlikely you have two faulty ones. I guess you have not ordered SD cards with OS on them, but are writing the cards yourself. If ...

Hi all I've got V5 working perfectly, many thanks to Thomas & everyone else who contributed. Now it's all working as I want it I thought I'd backup the SD card. Having tried and failed in Windows (cyclic redundancy check error message) I thought I'd let the Pi do the work with a dd command. I manag...

Apologies in advance if any of these make you say "Does he think I'm that stupid". :) 1. The HDMI lead must be removed before booting the RPi. 2. The composite video out (RCA phono jack) is a baseband video signal which needs to be connected to a baseband video input on the TV - typically a yellow R...

Currently there are two methods of getting video into a RPi: 1. USB webcam or USB video-grabber. However there have been many posts about USB webcams not working properly with the RPi. There are acknowledged issues with USB on the RPi. These are being worked on but there is no ETA for a definitive f...

Besides I am American and I consider it my god given and constitutional right to mangle the English language into American! :lol: Despite the many liberties that Americans take and have taken with the Queen's English, the interchange of "your" (the possessive form of "you") and "you're" (a contract...

Free does not mean worthwhile in this case as I see a problem in YOUR grammar also in that "says" should be more like "said" should it not. None of this is helping the OP so maybe stick to the content of the thread rather than focusing on a miniscule grammar problem. @Vindicator 1. Seeing as you ha...

Is it possible that the recording is in dvr-ms format - you do mention Windows Media Centre? If yes, you might care to look at http://www.raspberrypi.org/phpBB3/viewt ... 35&t=18733
