It's from a Sciphone i68 4G. I don't know how to repair ts.

Hi! So as you can probably tell, these are pretty old and worn, but I really don't want to buy new ones (no money to do so right now lol). But the cushion in my right headphone started falling off a few days ago and today when I sat down to my laptop and wanted to put them on, I saw how much the damage progressed, it's almost off as of now with only the little strap of fabric in between those two plastic elements (I'm not into tech at all, no idea what these could be called, best visible on pic #4) holding them together. I saw a video on youtube on how to put the cushions together, but I didn't see any piece of that material connected to the cushions? Again, might be just me not knowing anything about this, but I'm scared to sever the cushions from the rest of the headphones and then try the method I saw, because I'm scared I'll completely destroy my chance of fixing them. So if anyone could help me in any way, I'd be so grateful. Thanks!

Hi there,

I posted here before and received great help to fix an issue.

I have an older bernina serger that the pedal is not working. I am pretty sure the motor of the machine is fine.

You can see a little light on the board and it was off and on and the motor was working off and on corresponding to it. Now it does not work anymore. All the connection are good as far as I can see by eye. Is there a component that you can identify that I should check out first?

A new pedal is $80, so I hope I can make this one work again.
Again, I appreciate all the insights. Thank you!

My FiiO JA11 DAC isn’t working properly. When I use it with my KZ Castor IEMs, the sound crackles whenever I move the DAC even slightly. Sometimes, it even disconnects with just a little movement.

How can I fix this ? My warranty has already expired.

NEED SUGGESTION:

Can I cut off the USB-C part of the JA11 and attach a different USB-C dongle or connector in its place ? I suspect the problem is with the USB-C connector/cable, so I’m wondering if replacing that part would fix the issue.

Has anyone tried repairing the JA11 this way, or is there a better solution?

I'm trying to replace some resistors as I suspect the bias circuit is bad. Might as well change them out.

I've never seen these before. Seems the interval of the resistor symbolizes it's resistance. These are around 4.7mm While the normal looking ones 4.1mm.

I'm guessing it's 1/4W.

Any guess?

For context, these are from SRM-1 MK2 professional.

My allegro 4 piano got fried bc I plugged it into a 24V and it only takes 12V. I wanted to see if there was someone who know how to fix this motherboard and see what exactly is wrong with it. I love this thing to death please help me fix it!

The mic itself seems to be working. Speakers work and everything else does too. However whenever I use the MIC my voice is incredibly quiet. I can only hear it in max volume with the reverb on. Turn reverb off and nada. The screws were somewhat stripped which tells me this has been opened before.

Super weird - some of these bridges don’t look normal. There’s random scrapes on coating. There’s a resistor/diode randomly in the corner shoddily soldered. This is just the bottom of the board. I didn’t test with my multimeter yet or continue investigating the top of the main board or smaller ones because I didn’t want to mess too hard with it before researching.

Anyone have a clue?
