Hi, I just got my raspberry Pi today and was playing with it fine on the firmware that came with the image download with clear picture and no interference with both the standard config.txt and with overscan disabled, but when updating to the newer firmware with Hexxeh's rpi-update command, the interference issue described on this page started occurring (although with red dots rather than green like the picture). It did go away when setting the config_hdmi_boost to 4 - but it might help others to note that this could be caused by a firmware update, and not necessarily mean that something is broken. Although, I do find it strange if the "defaults" were changed as it causes this problem. [[User:Adammw|Adammw]] 09:53, 14 June 2012 (UTC)

New Power/startup issue

I'm seeing a symptom not yet described on the page.

The Red PWR led is on. The (normally) green led for OK is not, except for a tiny green dot in the center of the led. Or is this point 1.2?

In my case the board does not boot at all (no video, no flickering leds). According to Farnell there might be an issue with a recent series of boards that all seem to have this behaviour. But this still needs to be confirmed.

I still have to test some other distro's and SD cards to exclude a few failure modes.
