Hello all! I need some help figuring out how to resuscitate a CR-620.
The problem:
When the unit powers on, the red LED light for AM/FM comes on but the relay does not click out of protection.
The symptoms:
I opened it up and found some of the transistors and the variable resistor have a blue-green residue on them. Also, the plastic tube containing some leads has been burned. There are four ceramic looking resistors and a braided fabric covering another component beneath the plastic tube.
The parts that look fried: TR709, 710,713,717,718, 719, 720, 721.
I am a bit of a noob to electronics but I know enough to get in trouble
Can anyone make sense of this? Any help is much appreciated. Please be a detailed as possible and dumb it down for me. Thanks!
