Problems with hifonics brutus 1206d amp

Set your meter to ohms and touch the probes to the burned area. Place them as close as possible without them touching. Does the meter ever change from OL (or whatever it reads when the meter leads are not connected to anything)?

ok like you see in the picture not all is burned and by the way sorry to sound like very desperate i get really nervous when it comes to fixing car audio,
anyways you want me to turn my multimeter to ohms and test the burned part ?

[Perry Babin]

Yes. If it's not an auto-ranging meter, set it to the highest resistance range.

ok boss did it but where all that is burned dont have resistence

If no part of the blackened area caused the meter to change from whatever it reads with the probes not touching anything (no matter how close together the probes were), you don't have to cut the burned area away.

To replace the SMD parts, you'll have to use discrete parts as shown in the photos I posted. You'll need two 1N4148 diodes, two 220 ohm resistors and two MPSA56 transistors. You'll have to scrape the traces and wire the discrete parts as shown. The collector legs (leg 3) of the MPSA56 transistors are soldered to the ground plane on the other side of the board.
