I’m working on this one. From outside it seems a fine set, but inside is rather cheap. All Samxon 85°C grade caps. Those close to heatsinks are toasted.
I find toasted glue around DSP (Decoder) PCB heatsink (with 12V and 5V regulators). Tracks corroded by roasted glue, 12V track is burnt and open.
I clean everything, removing heatsink, large caps and even rectifier bridges (2 DB104G). Repair tracks, replace C102, C94, C93, C143, C141, C144 that are "tanned" from "heatbathing". Now there’re all voltages (12V, 5V, -12V, 2.5V), but still no sound. Damn, what a crap!
I’m getting SM from ET to keep wasting time on this.
