Default Pioneer DEH-P5800MP

I got this in for repair . The guy said he was hooking it up to a cae battery to test it . He said he hit the case of it to the positive terminal of the battery.

Now the unit is dead. I opened it up and repaired a broken trace on the circuitboard but the unit is still dead.

Any ideas on where to look next??

Do you have continuity between the case of the head unit and the ground wire coming out of the head unit's wiring harness?

Yes i have continuity between the ground wire on the harness to the case of the unit.

The 10 amp fuse in the back of the unit tests fine also

If it has a ribbon cable that connects the face to the main board, that cable could be defective which would prevent it from powering up. See if there is any oscillation on the oscillator pins of the microprocessor (pins 12 and 13). You'll have to set the scope probe to 10x to prevent loading the circuit. If there is oscillation, it may only need the ribbon. This is one of the problems with head units that use the ribbons. You almost always have to replace the ribbon to eliminate it as a possible problem.
