Raspberry Pi (no video, doesn't appear to read SD, hot chip)
I just got my Raspberry Pi (Model B 512MB RAM). I have tried everything and can't get it to work.
I've tried 3 different power supplies with a minimum of 1.5 amps. I've tried using 3 different micro USB cables in all the possible combinations with the power supplies I have. The red LED always comes on and I've tried measuring the voltages on the board and I got 4.94 to 5.2 volts.
I first tried it with my TV plugging it into 2 different HDMI ports (one that I have my video disc player on and the other I have my slingbox on). I tried the cables that I've been using for the player and tv slingbox plus one other really short cable (1 ft). When those didn't work I tried using the composite video out instead. At work I tried plugging it into a monitor using an HDMI to DVI adapter.
I've tried wheezer, fedora, archlinux, and raspbmc on 3 different SD cards (2, 4, and 8 GB). I read somewhere that the green ACK LED should flash when the SD card is being accessed. It never does on my board. Only the red LED is on.
The big chip in the center of the board seems hot to the touch but I don't know what the normal operating temperature would be.
Any suggestions? Adafruit suggested I post this here so that if someone is able to help me it may help others as well.
