    When you have replaced the cap, and you have only the red led, and all the voltages seems to be there, and you do not have any serial output, and also not be able to make a connection to the board by jtag.
    Than the most logic thing to think is a issue with the cpu.
    Most likely not defective, otherwise some voltages should often drop, but more likely some bad contact to the motherboard.
    An reflow may work, or re-balling, but both are risky to preform as also could be fatal when it's going wrong.
