The Stages Of Grief In Repairing A Trinitron Found In The Trash

Sometimes you see a project just staring at you with proverbial puppy dog eyes and you just cannot look away. In the case of a once rather nice Sony TV it was the smooth 32″ Trinitron CRT that gave [Happychoice] that look when he came across it along the side of the road. Naturally he had to beg the owner of the junkyard to please let him adopt the pupp^Wjunked TV and attempted an ill-advised repair.

Some later sleuthing revealed that this poor TV had been sitting on the side of that road for at least six years, exposed to the worst that the Italian weather and local fauna could do to it, so it was no surprise that all he got out of it even after cleaning and some repairs was a sad triple-blink of the power LED. This indicated that something on the control board was very unhappy about the status of the power supply.

Over the course of a few months this project went correspondingly from careful optimism down to the depths of depression, through the fields of bargaining and into the blue skies of acceptance of a likely far more involved repair session than originally assumed. That said, the CRT itself looks to be in pretty good nick, as do the PCBs barring the few sketchy resistors that already got replaced.

We would like to congratulate [Happychoice] on the acquisition of a fun new repair project and wish him all the luck on bringing this beast of a TV back to life.

Fixing A JMicron-Based M.2 USB Enclosure That Stopped Working

As useful as USB-to-M.2 SSD adapters are, sometimes you come across a bit of a dud. A case in point is the Orico-branded TCM2-C3 that features both an attractive clear case and in its earlier revisions a JMicron controller-based circuit that apparently degrades over time, causing erratic boot behavior. After implementing a fix a few years ago, [Mark Furneaux] can happily report that the thus fixed enclosures are still working.

These faulty board revisions feature the JMicron JMS583 controller IC, which has a 1.0V core voltage input pin. Apparently to save power, Orico designed the board to target the minimum ~0.95V core voltage per the datasheet. Apparently due to component drift or degradation, this lower core voltage is after a while often not enough any more to start the controller, which thus translates into an unresponsive USB device and presumably some panic about lost data.

Although [Mark] doesn’t describe the fix in detail, it entails bumping up this core voltage to something closer to the nominal 1.0V, which restores functionality at the cost of presumably a measurable amount of extra heat production by said controller.

Later versions of the Orico TCM2-C3 enclosure switched from this JMicron controller to a Realtek one, which so far appears to be noticeably more reliable. Although Orico kept the same model name, the transparent enclosure makes it at least a snap to see which revision you are dealing with.

Repairing A “for Parts” Canon 7D Mark II DSLR

The exciting part of buying a ‘broken, for parts’ off a site like EBay is that you rarely know exactly just how ‘broken’ it truly is. Even if the seller insists that it’s thoroughly buggered, you just might be able to eke out a fix with some out-of-the-box thinking and plucky ingenuity. Such was the case for [Dieter Vansteenwegen] who gambled on a cheap Canon 7D Mark II DSLR body that was sold for a mere €180 on account of said broken condition.

After confirming that the DSLR’s condition was basically as described by the seller, with nothing on the LCD or HDMI output and the auto-focus not working while partially pressing the trigger button, but still taking a picture when fully pressed. Sometimes it would also show a standard maintenance message on the LCD, so clearly it ought to be working. Maybe the camera’s processor was just being chronically unhappy about something, in which case an easy fix might be possible.

As anyone who has ever taken a digital camera apart knows, you do not simply pop them open for a quick look. Somewhere in the nightmarish contraption of flatflex cables, PCBs and endless sub-assemblies there might be a fault, but where to start? Fortunately with some support from the custom Canon firmware community Magic Lantern and the website Photo Parts UA for reference images he was able to start tracing a number of pertinent signals.

With the auto-focus hint as guide, this was traced back to the MPU, which turned out to have a floating signal on the auto-focus pin that got interpreted as ‘active’. Likely the internal pull-up got damaged due to the use of an external trigger module as there’s no real protection on these lines. One bodge wire later to create an external 3.3 V pull-up the DSLR happily sprung back to life.

In terms of parts this definitely was a cheap repair, but it comes with the prerequisite of having the skills and equipment to perform said repair. Still, massive props and congratulations to [Dieter] for saving this DSLR from being merely a device to be picked over for parts.

A cardboard box (top left), set of instructions (top right), and a disassembled gaming console (bottom half) are strewn across a light blue tabletop, giving the impression that repair is impending.

Team Repair Breaks Things To Teach People How To Fix Them

Would you buy a broken device, fix it, then return the repaired item? [Team Repair] hopes you will.

Many people would rather repair what they have than have to get a new device and deal with all the annoyances of shopping and getting used to a new item. The problem is, most people don’t have any experience fixing their broken electronics and are intimidated by the process. [Team Repair] has found that helping people through the process the first time is a big confidence boost, especially when they have a test piece to work with.

[Team Repair] started with workshops and now has a “Fixers Club” subscription box for 8-14 year olds where they will send a broken device every three months to fix. After the device is repaired, it gets sent back into Team Repair, or iFixit in the US, to be broken again and sent to the next fixer. For grownups, there is a similar smartphone repair kit, but it’s currently waitlisted. If you’re in the UK, they even have a classroom program if you want to recruit larger groups into your fixer corps.

Curious about other ways to get into repairing your own things? We don’t recommend starting with smart rings, but learning analog repairs like zippers or turning a laptop into a desktop could be good places to start?

Repairing A RED Cinema Camera On The Cheap

[ALT CINE] took a punt recently when purchasing a damaged RED Komodo camera online. In functional form, the 6K-capable camera sells for several thousand pounds (or dollars, or euros), whether used or brand new. However, [ALT CINE] was able to score the damaged unit for just £700. The question was—could it be repaired and turned back into a functional camera?

Things looked promising from the drop. The camera had just 3 hours of usage recorded in the firmware, and the casing seemed to suggest it had little use. However, the problem was soon revealed to be serious as the image sensor itself appeared to be damaged. Some research provided hope though—that the damage could be limited to a glass layer in front of the sensor itself that had delaminated.

Thankfully, disassembling the camera was easy enough thanks to its modular design, and [ALT CINE] soon had the sensor block on the bench for further examination. The cause of the issue was apparent—overzealous cleaning leading to fluid getting stuck to the rear of the filter in front of the sensor. Simply popping off the filter, cleaning and drying it properly, and reassembling, was enough to get the camera back to fully operational status.

RED’s repair service quoted $695 for a glass filter swap and $1,395 for a full sensor change. In contrast, [ALT CINE] was able to demonstrate that this repair was something easily within the realm of an intermediate camera tinkerer and it cost almost nothing to achieve. The video also covers an alternative potential repair route, wherein a DSMC2 filter can be subbed into a Komodo camera if the damage to the filter glass is otherwise unrecoverable.

It’s rare to get this lucky when it comes to repairing big-dollar cinema cameras like this one. We’ve featured some other great deep-dive camera repairs before, too. Continue reading “Repairing A RED Cinema Camera On The Cheap”

EU Adds Exemptions To User-Serviceable Batteries Rules

Built-in batteries put a timebomb inside devices, with especially the calendar aging feature of Li-ion chemistries setting a hard limit on when you’ll have to toss the device or figure out a way to replace the battery somehow. Here the EU’s Battery Regulation policy with the 2027 implementation of the user-serviceable battery requirement provided a lot of hope. Now six new categories of exemptions are diminishing what could have been a bonanza of easy repairability.

Most notable here are smartwatches, fitness trackers, wireless earbuds and other so-called ‘wet devices’, which as GSMArena also notes is an area where having a user-replaceable battery might affect features like being water-resistant. Something which is also relevant for e.g. outdoor wireless speakers. There’s also a new exemption for smartphones, where if its battery retains at least 83% of its original capacity after 500 charge cycles, battery replacement has to be only replaceable by professionals. Which is probably code for ‘glue, hotplates and prying tools’.

Considering just how daft of an idea built-in batteries are, this is somewhat disappointing to see. While it’s understandable that ‘wet devices’ get such broad exemptions, it should be noted here that advanced technologies like gaskets are neither complicated nor expensive. You can even hand the average user a tube of RTV silicone and let them go to town on a part in the happy knowledge that there’s never such a thing as ‘too much’ RTV silicone.

It is likely that there was some pressure from the industry on the EU to not change too much, but at the very least us happy few in the EU will be getting a new Nintendo Switch 2 with easily replaced battery in both the main unit and its controllers. For the average rechargeable device you keep kicking around the house this should also still apply as long as its manufacturer cannot squeeze it into one of these exemption categories.

The Right to Repair battles shall continue.

Hacking Around The Financial Pain Of New 3DS XL Top Screens

With Nintendo’s 3DS experiencing a bit of a renaissance lately, prices for functioning systems have shot through the roof. Getting a busted one with a broken screen is a lot cheaper, but then you run into the eye-watering price difference between a replacement top screen for the regular version and the larger XL variant. The latter costs about the same as a whole new used 3DS, while the former goes for peanuts. Here the solution is obvious, with [Skawo] demonstrating how they hacked the cheaper, smaller top screen into a New 3DS XL.

The price difference on AliExpress as shown in the video is on the order of $120, with the smaller screen going for less than $10. Since they both use the same connector pin-out and display technology, you can plug either display into the New 3DS XL mainboard.

Where you’ll run into issues, other than the replacement display being obviously not XL, is the physically shorter flat flex cable for the controls that forces the display to be installed in an offset manner. You need jailbroken firmware like Luma3DS here to adjust for the screen offset. Filling in the missing screen real-estate is the other issue you have to patch over somehow, which was done here in barbaric fashion with some cardboard.

Beyond that it does work, and as a fix to at least get a broken New 3DS XL back into the game it’s worth considering. Do note that there’s a difference between regular 3DS and New 3DS (second generation) screens with neither being compatible, so be careful before you try such a fix.
