iHip Headphones: headphones won't turn on

Sun, 14 May 2023 01:42:56 -0700

My problem with the iHip headphones is that it won't turn on and when I put it on the charger it will turn red but when I put it on the charger it wouldn't do anything not even make any sounds and after a while I think I noticed that the red light would just go off and the thing is they were working perfectly fine this morning. Does anybody know anything that could help cause I would die if I couldn't use these headphones...

Boat Rockerz 450: The slider broke, superglue is not fixing it.

Sun, 07 Dec 2025 10:16:05 -0700

I have been trying to stick this with superglue but it keeps falling apart, even after waiting 10-20 minutes for it to cure. Can someone suggest alternative methods to stick this? The headphones work fine its just the slider thats broken.

T004: Why are my wireless headphones not charging?

Mon, 26 Aug 2024 08:11:06 -0700

I have G-Cord AYM T004 and they are flashing red and blue slowly, which I think means it needs to charge, but I had them charging overnight and their normal charging time is 3 hours, they just aren't charging.

Tue, 05 May 2026 04:00:52 -0700

Experiencing an issue where one of the earbuds is not charging properly when placed inside the charging case. I have attempted to charge the problematic earbud using another earbud's case, and it charges successfully. However, it does not charge when placed back in its original case. How can this be resolved?

Mackie HR624 mk2: Dead Mackie HR624 MKII measurements... check my work?

Tue, 23 Dec 2025 19:50:12 -0700

I have a dead Mackie HR624 MKII part of a pair I got for free. The other one powers on, but emits only static.

I want to use this as a learning opportunity to do test measurements and diagnosis and hopefully fix the problem.

Schematic: https://www.audioservicemanuals.com/m/ma...

I am starting with the dead monitor first. Like I said, dead, no power light, no sound. Fuses checked and are good. A visual inspection does not reveal anything obvious. no leaking, bulging capacitors. no shorts or burnt parts of the board. the grounding wires look ok at the connection point, no corrosion, but maybe they could be cleaned up anyway.

I did a Transformer AC Output Test and got ~31V AC from the center wire to each outer wire and ~64V AC between the two outer wires, so it seems power is being correctly delivered to the main circuit board.

Next I did a Main DC Power Rail Test and measured 0V DC on both test points.

So that led me to the bridge rectifier. I got the correct forward voltage drop (~0.6V) and an open circuit reading in reverse.

So I did some point-to-point continuity tests

AC Path (Transformer to Rectifier): PASSED. There was a good connection.
Ground Path (Center Tap to GND): PASSED. There was a good connection.
Positive DC Path (Rectifier + to Capacitor C39): FAILED. Showed "1" (no connection).
Negative DC Path (Rectifier - to Capacitor C48): FAILED. Showed "1" (no connection).

I'm guessing there is a physical break in the copper traces on the PCB? If so, reflowing that is beyond my knowledge and skill probably. But I could do small jumpers?

Or am I misunderstanding the result of the measurements?

I can share pictures if anyone can help me see the issue the measurements are pointing towards. But now i feel a little over my head.

Thanks.
