Hi all, Does anyone know where I can find a schematics diagram for my SONY WM-BF60? I've looked all over the internet and can't find one and presumably I'll need it to test the circuit board for continuity? Otherwise I have no idea where I'm supposed to be placing my multimeter 'wands' or what/how to test it. Many thanks Paul
Hi, service manual here: https://freeservicemanuals.info/en/servicemanuals/viewmanual/Sony/WMAF61/WMBF56/WMBF60/
Hi mrp32Dave, Thanks so much for your link you gave me to freeservicemanuals...however, I've tried that and can't seem to access any of the pages and/or service section...it just looks like its the front page only of the manual...am I missing a way of accessing the info? best Paul
Well, I've managed to download the schematics diagram for my Sony WM-BF60 and I'm looking at it now...having never used a multimeter to check the PCB before I'm not sure how/where to start. Can anyone recommend which pathways to test and how to find them from looking at the diagram? best Paul
Hi again all, I've been scratching my head at the schematics diagram on the service manual and think I may have found a working methodology...First I look at the circuit diagram and follow certain paths that seem to connect together (though I'm still trying to understand all the symbols and circuit 'language')...then when I think two points are connected I got to the other part of the manual which also shows the component number but in a more 'realistic' graphical way that looks like my circuit board...I can then find the two components or points to test more easily from there and make sure I get a beep on my multimeter! I'm not sure if this is an efficient way of testing everything...it will probably take days if not weeks to test each component/point like this but I've never done it before so just trying to work it out...feel free to suggest alternatives? Also, I've noticed a couple of components don't seem to create the beep with a continuity test but the whole board generally looks like it might be covered in electrolyte from leaked capacitors. Marian recommended I could actually dip the whole board into IPA and I'm thinking this might be a good idea because I've already treated it with IPA using cotton buds but it still looks like the solder is dull and the board generally a bit of a "matt" type look to the components/joints...what do others think? My main concern is obviously making sure any continuity tests are not being compromised through a layer which is stopping the probe from making the connection...and the components are sooo small its also an art just to get the tip on them! best Paul
