One day while attempting to clean up my wires a little bit my acc resistor cover came off. My acc wire touched an open ground wire (needless to say I was being very careless). It damaged my computer. I got the computer replaced. My stock HU works just fine. My tv does nothing. It sounds like a cd is loading but my screen isnt moving at all. Its getting power because the security light blinks when panel is off. Can anybody help me please? Thanks in advance for any help or any tips.
