Hello,
I'm really hoping somebody on this forum, who have way more expertise than I, can help me with something.
I am searching for the schematic to hopefully repair my 83 yr old mother's console stereo system, it's a 1979 Soundesign 5595 w/ turntable, AM/FM stereo receiver, cassette and 8-track tape, everything works but there's a loud bass hum when using the cassette player and the FM radio needs to be turned up to full volume to hear it, every other part seems to work like it should with the exception of burnt out dial lights and needing new belts.

since i couldn't find schematic or boardview for this model (LA-K062P), i use closest board model found here https://www.badcaps.net/forum/troubl...-and-boardview
the schematic share same marking for each component, using same PD-Controller, same BQ25710, the only different is the battery cell used. LA-K061P uses 3S battery while LA-K062P use 4S battery per schematic.

Hello everyone, I come here in search of wisdom and hope.
I got this laptop with charging problems, apparently it charged ok while turned off but it would not charge while powered on, anyways I was doing initial measurements looking at the voltaje on the ID Pin, it is a 135W DC Adapter and the pin actually measured 1.9V that looks ok, anyways, while doing that, I accidentally shorted the ID pin DETECT(ID) with one of the 20V pins, sparkles and it automatically killed the TVS Diode PD102, and also made a cute burning hole on the middle of the KBC or EC chip UE1, it is a IT8227E-128...
