Good day bros. I am working with a Fusion 2250 watts monoblock model: GS-DA12250. The amp keeps clicking only and does not power on. It had adhesive coating near the power supply section near the filter capacitors (as shown encircled in red from the picture). I removed the hard adhesive coating and I believed the coating became conductive after some time which caused the components under, ZD3 and one resistor to blow(also encircled in red in the picture), actually it created a small hole in the between the the 2 blown parts. Measuring the voltage drop on the on one of zener diode (ZD2) adjacent to it 5.5v as reference, I replaced the blown parts as in trial and error method but the amp just trying to power on , the power goes on and off, continously. Can anybody tell me the correct value of these parts, ZD3 and resistor(encircled). I f you came across this amp? or better if anybody can share me the circuit diagram of this amp. because not sure if a trace was cut as well from the hole. Thank you very much and more power to all.

ok Perry . definitely, I will once I am back in my bench this afternoon. Thank you always for your prompt response and willingness to help always. After 2 years in this hobby, Still I am in the process of learning because I believed that repairing car audio amp is neverending learning. Getiing your tutorial guide truly is big help to me, I had learned a lot from it, but still more to learn ha ha. Please inform me if you have new updates on the repair tutoria.l More power always bro. Thank you.
I have things I could add to the tutorial but with less than 1 per month in sales, there is no reason to add any more to it.
