OPEN NEW RULE UPDATE. Read before posting.

18 Upvotes

If your device has a make and model number, please include it in your post. We've updated Rule #1 to emphasize this. Essentially, if your device has a make and model number, you should let us know what it is. FCC IDs are also helpful, if applicable. Below is the text of the updated rule:

Posts should be clear and on-topic

"Posts should focus on fixing broken electronics, ongoing or completed repair projects, or original content (OC) guides and tips for repairing electronics. Posts must include any available make and model number information. When asking about an individual component, you must provide details about the circuit and/or the device it belongs to."

If you forget, you can always add this information in a comment. If the model number is particularly long, you can take a picture and upload it in the comments.

Including the make and model number makes the information in your post searchable for others who may encounter the same issue. It also provides context, such as where the device came from, who designed it, and what it's for.

Other One of the biggest cheap upgrades to our workbench

Post image
28 Upvotes

We recently bought a Siglent 4 channel scope to replace our old trusty Rigol.
One of the challenges we had is that the equipment shelf is a bit of a reach since our bench is deep.
This cheap (mostly) DIY solution made a night and day difference!
The ability to move the scope all around the bench, bring it closer to the DUT, especially when probing those hard to reach areas, and easily move it out of the way with one hand, is a life changer!

The arm is a standard gas spring VESA monitor arm that you can get on Amazon for ~$35.
The Siglent VESA mount adapter was 3D printed using PETG-CF, from a free tried and tested design by printables user aeberbach. It's an ingenious design that uses the scope's handle as a lock mechanism for the bracket.

After using it for a while, we figured that we were missing 2 things - a handy storage compartment to for probe attachments, clips, etc., and a probe hanger to solve the unavoidable messy entanglements of the probe wires.

Then we thought, "why not add a DMM to the bracket?" so we did.
Our trusty vintage HP DMM was way too big and heavy, so we settled for a cheap XDM1041 digital DMM that works well for most of our daily needs. They come under different brand names, but are all the same.

Then we designed a bracket that attaches under the scope mount, and you can see the results after several iterations and improvements. It has a convenient accessory compartment, and a probe hanger for all 4 probes on the right.

If anyone is interested in the print files for it, let us know and we'll share it online for free of course. The idea can be adapted to any small DMM that you already have, but the files we have are specific to this model so we weren't sure if anyone would be interested.

Have a great weekend!

OPEN Overlay for control damaged.

As you can see the control button overlay is damaged. Is there a place that makes stuff like this?
For that matter can you just but the Lexan material?

I did find this company that makes these things.

canadastickerking com/more-specialties/lexan-overlays/ This link is missing the beginning part & the “dot” so I can include it. Only lets me post a picture or a link but not both.

OPEN Want to repair a (fairly)old Subwoofer

2 Upvotes

Hello everyone. I would like to try to repair an Old Subwoofer. Can someone help me identifying this part?

The one with the "LT-Sub2" marking ripped off the board. I soldered it back to place and I am able to start the Subwoofer and get sound of it - so far so great. But over a certain level (volume/bass) it just turns itself to standby. The part I'm holding is part of the Power Switch - that do I know.

I think that part is the one that is broken.

It's a Teufel C200USB Set, the subwoofer a Teufel CC200SW If that matters.

I would really like to get it working again.

Thank you very much!

Hello, has anyone here ever replaced the cells inside the LP-E4 battery pack? If so, were you successful? I've swapped mine out, but I believe it'll need some calibration, but I don't think I can force a calibration myself.....the charger has charged the battery pack, but the camera still shows it as empty, so looks like it's out of calibration of some sort!......thanks.

Have had these Crusher Evos for years and they are my favorite headphones by far. Of course I had to drop them, and now they refuse to connect.

They were gifted to me years ago, but I'll do anything to get them up and running again.

When plugged in, music can only be heard on the right side, but both haptic drivers thump away. "Power on" still plays through both speakers, but it no longer says "pairing," nor does it appear in any bluetooth menu.

I took them apart but see nothing abnormal or disconnected. I'm thinking it's an issue with the motherboard itself. Any ideas?

OPEN OnePlus 6: powering the phone from a bench supply through the battery connector board, no boot. With what I should replace the bms baord?

1 Upvotes

Hi everyone,

I recently bought a OnePlus 6 and I’m trying to power it from a bench power supply instead of the battery with the battery removed bms board. Voltage used: 3.8 V

Problem:

The phone doesn’t turn on or show any sign of life. While handling the connector board, I think I damaged it with heat while solding.

Questions:

  1. Any ways to check if the bms board still works? (I lost the battery)

  2. Should I buy a new battery or using a battery flex can work? If yes can you show me one?

Any other tips are well accepted, thanks

OPEN Guys does anyone know what most likely could be wrong on these tailight boards or how/what to test to locate an issue I’m having. I’m new to this

Hi guys, so these boards are from a taillight and I’m trying to learn how to fix it.

I’ve not removed it yet from my own but I have some experience doing that as I replace lenses/housing etc on headlights so there’s no issue get the board out. The issue I’m having is identifying how to find the problem.

The issue with the tail light is the brake lamp when on the car (which is the inner ring of LEDs on the board) flashes once then turns off. What steps you think I should take to identify the issue?

OPEN iPad 2017 pro 12.9 touch damaged - ribbon and nearby circuit problem

Thumbnail
gallery
1 Upvotes

I replaced a faulty battery on my iPad 12.9 and it was successful. However I must have been carelessly broken the ribbon connector to the screen and you can see one of the connector is broken and I think two nearby components are fried. The iPad screen now is showing something but the touch does not work.

Before I attempted to DIY repair I would like to check my odds:

  1. How do I find out what components I should be replacing? And where I can find the schematics?
  2. I have a hot air gun for replacement but not a preheat platform. The problem I encountered in the past mostly is the air gun is too strong and blow the nearby components out of their places. A preheat platform can prevent that?
  3. Should I use heat tape to protect the nearby components? I have had tried but the effect was not very good. May be it was just my poor skills?

  4. I don’t have a magnifying camera. Do I need one?

Thanks!!

OPEN LattePanda Mu N100 dead after sudden power cut – Replaced 1uF ceramic cap next to bulk capacitor but still no power

Thumbnail
gallery
1 Upvotes

Looking for component-level diagnostic advice on a dead LattePanda Mu compute module (Intel N100).

The Failure:

  • The module was running on its carrier board when a sudden hard power cut/outage occurred.
  • Since the drop, the board is completely dead: no LEDs, no fan pulse, and no response to the power button.
  • The carrier board itself is confirmed fully operational (tested and runs properly with an i3-N305 module).
  • The SPI BIOS chip was already cleanly reflashed externally with official dumps, but it made no difference.

Hardware Findings & Attempted Fix:

  • Inspecting the power circuitry, I found a missing ceramic SMD capacitor sitting in parallel right opposite a large polarized bulk capacitor (marked with a + and labeled WE8/EE7).
  • We soldered a replacement 1uF ceramic capacitor onto the empty pads, but the board still will not turn on or draw power.

Questions:

  1. Based on the bulk cap markings (WE8/EE7) and standard x86 compute module layouts, what rail is this stage filtering (main 12V DC input, or a primary 5V/3.3V buck rail)?
  2. In an abrupt power cut, is it common for the polarized bulk capacitor (left) or an adjacent high-side switching FET to fail short alongside a blown ceramic cap?
  3. What key resistance checks relative to ground should I probe next around this circuit to identify why power isn't sequencing?
