    Hello!
    I'm brazilian and firstly please sorry for my english.

    I came to tell my sad story hahaha

    My son spitted juice on my receiver. At the same time I shut off the equipment.
    After the clean there is not powering on. Going on protection mode but show the info percent from DC protection.
    Ok. Looked at superficially I found some resistors opened. Removed and soldered the new but at the moment in connect the cables, I've inverted some connections (images 1 and 2) and since then the receiver not display anything (only horizontal lines for 0.5sec).
    I hear the relay arming and desarming rapidly.

    With tests on the power supply, the line that should have AC12v (image 3), have AC24v. I don't know if it's the problem.

    Can anyone help me in this problem?
    Thank you in advance for your support.

    I would definitely recommend not powering the unit on again until we can figure out how to get the AC24v back down to AC12v
