    Yeah the regulator is outputting between 0.5-1V over what it should.

    My power supply is giving like 10-10.5V though even though it’s a 9V supply, might this cause it?

    (Edit: Just tried with a more reliable power supply, same output from the regulator)

    Tried all the other suggestions and still nothing.

    Thanks for the patient help. I’ll try that and get back to you.

    The voltage across the regulator (the ‘bottom’ two horizontal pins) is like 4.8-4.9V so this seems about right.

    But across the VCC and GND of the chip is about a volt higher, 5.8-5.9V, same if I measure over the C2 capacitor next to the regulator.

    Interestingly, there is voltage across the output of the chip and when I press reset the voltage drops and then comes back up. Doesn’t this sound like it’s working?

    But as soon as I plug in the audio and/or video cables to the board, there’s nothing.

    I thought this seemed a bit weird earlier, I should have said, it seems like I have about 8V across those pins (I had already found that datasheet and checked that 🙂 )

    I also have 0V across R2 and R3.

    I was using the hackvision with an easycap usb adapter to play through the computer so I didn’t bother soldering the PAL jumper. Though I tried with a TV too just in case.

    As for the FTDI cable, I assume the green wire should be on the side where the board says green?

    [edit] just checked again and now it’s about 5.8V :S

    Unfortunately I don’t have an Arduino board I can use to test.

    I’m in the UK, not sure where it was bought from since it was a gift. I might assume Cool Components though. But I could find out for sure if needs be.

    Here’s a couple of pics, thanks.

    Yeah I’ve looked through all the troubleshooting, and have a correct power adapter.

    No sound or anything. I also can’t get Arduino IDE to upload to the chip (I have the correct cable and the correct COM port and stuff selected), so maybe the chip is dead I dunno. Is there an easy way of checking where the problem is?
