Has anyone ever tried reviving an AIWA PB-3/4/5 lead-acid walkman battery using the "just add distilled water"-technique described in some YouTube...
Thanks for pointing out my mishap. I am aware of the PCB label for the LED, but simply mixed up two components. The issue has been resolved.
I am trying to identify a diode I found on the DC-DC converter flex PCB inside my WM F707 that I am trying to restore. Could anyone help me find...
I replaced it, but there was no change in behaviour, unfortunately, When I accidentally got the Walkman working one time, I noticed that the 3,5V...
Thanks, @Squiggly. I appreciate your support. Unfortunately, the matter is more complicated. :) The DDC FLEXIBLE BOARD is what's in the copper box...
I am restoring a Sony WM F707 walkman that has been dead on arrival. It does not react to any inputs, on-device or on the remote. I checked for...
As usual, many thanks @Valentin. Let's tackle the first problem first; it will take a while before I can check the voltages on the relevant ICs....
Thanks, @Romulo Lubachesky. I am 99% sure that the buttons are fine. As far as I can say, they do what they are supposed to do. I have turned my...
Many thanks, @Romulo Lubachesky, that was extremely helpful. I've now had time to repair the clutch. Sadly, while things seem to have improved,...
Thanks, @Romulo Lubachesky, you seem to have been right. This is what I found: [ATTACH] Is the idea here that you have: 1) lower, felted part...
Many thanks for the hint! I think I got what you did. Not sure if this will resolve my issue, but I'll give it a shot as soon as I find the time.
@Valentin, I have now had some time to dig deeper into the mech and have opened a new troubleshooting thread here:...
I am troubleshooting an AIWA alpha-2 walkman mechanism that doesn't want to autoreverse. The mechanism works perfectly fine in forward. Upon...
Many thanks, Valentin! It will take some time before I find the chance to open up the mechanism. I have yet to examine its functionality without...
I had thought of that before and done this now, but sadly to now avail. I'm not even very surprised as the switch board seems to be a tightly...
Also, the volume control is not digital here - it's analogue. There is a control wheel under the remote control. The +/- keys are used only for...
So, I eventually had some time to dig into this again. I cleaned the headphone jack, the head flex connector to the board, the headphone amp, and...
So, I gave this a try, but didn't succeed. I have a 4-pole jack, thus 4 points to solder to. I had initially soldered each wire to its own pole. I...
Thanks a lot, @Silver965. That looks interesting: I will have to have a look at the way I did it and will report back soon. I have been using the...
I am trying to wire up a Walkman remote with fixed headphones to a new 3,5mm socket so I can use my own phones. I cut off the old phones and...
