Well I just purchased a mint Avengers "The Pin". The original owner said that it was working with no issues until one night at a party, it was nudged hard and it thew up an "IO Error". From there they replaced the CPU board and the Node board. Neither fixed it. I bought it in this state and have continued to work on it.
When booting up with just the node board connected to 48V and RJ45 from CPU connected, it doesn't throw the IO Error. On the node board there is a 6V LED that flashes. As soon as I plug in the flat ribbon cable running from the node board to the main LED board, it drops the 6V down to 1.5V and says IO Error. It does this with nothing but the ribbon cable connected to the LED board. So I thought the LED board has a short pulling down the 6V. I just received a new LED board from Stern today. Plugged it in and it does the exact same thing.
I have called Stern support and David & Chas has helped some but it appears they have received absolutely no support from the engineering department on these pins. There appears to be no diagnostic menu for these machines either.
Anybody have any experience with either the Avengers or the Transformers? Would love to know how a known working machine boots up and how the 6V LED acts during this. Also make sure the node board is connected correctly.
This is the first Spike system. The CPU board appears to be working ok. All LED's are reporting with the correct voltage and it is talking to the Node board as long as I don't plug in the LED board.
