Thanks for the question. My name is Dan.

Just a couple questions so I can get a better idea about what's going on here.

1. Does the red LED flash, or is it solid? If it flashes, how many times before it pauses and flashes all over again?

2. Do you have a multimeter? Soldering iron? Or are you not interested in that kind of effort here?

Respectfully,
Dan

I would have to check the sequence of the red light. I have a sodering gun and a small multi meter that has dc/ac/check/k 9upside down U) and cont.

 

Is that all I need or is this going to be complex.

The blink sequence will help us narrow it down. We won't know the complexity of the issue until we can get some baseline diagnostics.

Ok, thanks. That's a +5V problem... either shorted or over voltage. Tough to say what the exact issue is without internal diagnostics. Might be the "G" board, the "A" or the "B." If you want to disassemble and dig in, just let me know... I have the schematics. Otherwise, sounds like it's time to replace it.
