Had a 2019 MacBook Pro come in with a swollen battery that was actively smoking

It was in my shop in Denver, and the owner said it just started smelling funny. When I opened the back, the battery pack was bulging and a thin wisp of smoke was coming out. I got it into a metal bin with sand, which is my go-to for this, and let it sit for a full day. The real problem was the adhesive Apple uses; it's a nightmare to remove safely once the cells are compromised. What's your specific protocol for a live thermal event beyond just the fire bag?

Working on a 90s arcade cabinet changed my view on cleaning boards

I was fixing a Street Fighter II machine at a retro arcade in Portland last year, and the owner insisted I blast the main board with compressed air before even looking at it. I did, and it blew a tiny surface mount resistor right off the board. Everyone says to clean first, but now I always check for loose parts with a magnifier and gently brush instead. Has anyone else had a simple cleaning step cause more damage?

Just saw a 2015 MacBook Air come back to life after a $2 capacitor swap

It had been a 'dead logic board' case for months, but a local shop in Tampa found the exact 0201 size cap that failed. Anyone else have a go-to source for those tiny SMD parts?

Spent three days chasing a phantom short on a 2018 MacBook Pro board, turned out to be a single grain of solder under a tiny capacitor.

Checked out a new repair shop in Phoenix and the soldering station setup was a real eye-opener

Honestly, I was at a place called Circuit Fix on 7th Ave last Friday. They had four Hakko FX-888D stations all lined up, but every single tip was completely oxidized and black. Tbh, it looked like they never cleaned them, just cranked the heat to max for every job. Ngl, I watched a tech there try to reflow a connector on a laptop board and it was a real struggle. Has anyone else seen a shop let their basic gear get that bad, and how do you even bring it up without sounding like a jerk?

Question about those cheap hot air rework stations versus a decent one

I bought a $70 no-name hot air station off a website last year, thinking it would be fine for occasional phone charging port swaps. The thing was a nightmare, the temp reading was off by like 50 degrees and the fan would surge. I finally spent $300 on a Quick 861DW last month and the difference is insane. The heat is steady, the airflow is smooth, and I'm not burning pads off anymore. It's cut my rework time in half on small boards. Anyone have a good middle-ground station they'd recommend for someone just starting out?

Pro tip: always check the power supply before you blame the main board

Last week in my shop, a customer brought in a gaming PC that wouldn't turn on, and he was sure the motherboard was fried. I pulled out my multimeter and found the 12V rail on his Corsair PSU was dead, so I told him he just needed a new power supply, not a whole new build. How many times have you seen someone jump to the most expensive fix first?

Finally gave up on the old hot air station and the difference is wild

For years I used a cheap hot air station from a starter kit, always fighting with it on small components. Last week I switched to a proper Hakko unit for a tough board repair. The precise temperature control and steady airflow meant I got a clean BGA reflow on the first try, something that used to take me three attempts. Has anyone else found that one tool upgrade just made everything click?

Shoutout to the tech who showed me a better way to clean flux residue

For years I'd just use 99% isopropyl and a brush, but a guy at a repair meet in Portland said to try a 50/50 mix of isopropyl and distilled water with a drop of dish soap. I switched six months ago and my boards look cleaner with way less scrubbing. Has anyone else found a better cleaning method that actually saves time?

I was reading an old repair manual and saw that a CRT television's flyback transformer can output over 25,000 volts.

Found that in a 1992 Zenith service guide, and it makes me wonder how many of you still work on tube-based gear and what safety steps you take for high voltage.

Question about the weirdest repair request I got at my shop in Boise

A customer brought in a vintage radio that had a family of mice living inside, and they asked if I could fix the radio without disturbing the 'tenants'.

I just fixed a 1980s arcade board by cleaning the edge connector with a pencil eraser

This Galaga board came in last month with a dead screen, and the owner said two other shops told him it was junk. I spent a whole afternoon checking voltages and chips, but the fix was way simpler. After pulling the main board, I saw the gold fingers on the edge connector were just dark with old grime. I gently rubbed them with a plain white eraser for about five minutes, blew out the dust, and reseated it. The game booted right up on the first try. Has anyone else had a modern problem with a fix this old school?

A repair job from 2012 that still bugs me

Got a call today from a guy who still uses the same Vizio TV I fixed for him over a decade ago. It was a simple bad cap job, maybe took me 45 minutes back then. The thing is, I remember that whole week because three other people brought in the exact same model with the same issue. It was like a weird, specific wave of failures. I charged him $60, which felt fair at the time. Makes me wonder what kind of 'waves' we'll see with today's stuff, where you can't even get a schematic. Anyone else have a weirdly memorable run of identical repairs from back in the day?

Tried a new flux paste on a tough PS5 HDMI port job

I was fixing a PS5 with a busted HDMI port and used my usual MG Chemicals 8341 liquid flux. It just wasn't cutting it for the heat needed on that big ground plane. Switched to Amtech NC-559-V2-TF paste, and the difference was night and day. The solder flowed perfectly on the first try. Has anyone else found a specific flux that really works for modern console board repairs?

I thought the 'freezer trick' for a dead laptop battery was total nonsense

A client brought in an old MacBook Pro with a battery that wouldn't hold a charge at all, and as a joke I told him about the old trick of putting it in a sealed bag in the freezer overnight. He actually did it, and the next day the battery reported 12% capacity and booted the machine long enough to pull his files off. It only worked for about 20 minutes before dying for good, but it saved his data. Has anyone else had a weird, last-ditch trick actually pull through in a pinch?

Changed my mind about using a cheap multimeter for board-level work

I always used a $15 meter from the hardware store, thinking it was fine for continuity checks. Last month, I was tracing a short on a Dell laptop motherboard and my cheap meter gave a false reading, making me waste two hours. I borrowed a Fluke 87V from a friend and found the problem in five minutes. Has anyone else had a similar experience with basic tools failing on complex jobs?

Fixed my first surface mount resistor with a $5 hot air station from the flea market

For years, I'd just replace whole boards when a tiny SMD part went bad because I only had a soldering iron. Last month, I found a basic hot air station at a swap meet and tried it on an old radio. I heated the area for about 15 seconds, lifted the bad resistor, and put a new one on cleanly. It felt like a real step up from my old way of doing things. Anyone have tips for keeping the nearby parts from moving when you do this?

Found a 1990s VCR repair shop still open in a strip mall near me

Honestly, I was driving through Mesa and saw this tiny place called 'Video Fix-It' with a neon sign. Walked in and the guy had a whole wall of just VCR heads and belts, plus a stack of about fifty old camcorders waiting for work. He told me he still gets three or four VCRs a week from people with old home tapes. Has anyone else seen a shop like this hanging on, or is this the last one in Arizona?

Chatting with a teacher friend about the right to repair

Honestly, I was fixing a busted laptop screen for a friend who teaches high school. She was telling me how her students can't even change a battery in their own phones without a warning message. She said, 'It's like they're being taught that stuff is magic, not just parts put together.' That hit different because I fix that 'magic' every day. I realized we're not just swapping components, we're keeping a whole skill alive. It made me think about the shop I run in Tacoma. Maybe we should do more than just fix things. Like, host a free weekend class on basic soldering or battery swaps. Has anyone else tried something like that to get people, especially younger folks, more hands-on with their own gear?

A customer's old radio taught me to check the simple stuff first

This guy brought in a 1970s Panasonic table radio that wouldn't turn on, and he was sure it was a dead power supply. I spent 20 minutes with my multimeter before he pointed at the volume knob and said, 'You know, it clicks when you turn it all the way down.' It was just the on/off switch linked to the volume pot, and the contacts were dirty. A quick spray with DeoxIT and it fired right up. How many times have you guys jumped straight to the complex fix and missed something that simple?

Shoutout to the old timer who told me to check the clock signal first on a dead 90s stereo

I spent two hours checking caps and power rails on a Technics receiver, but he said to probe the main crystal with my scope before anything else. Sure enough, it was flatlined, and swapping that 4MHz oscillator brought the whole unit back. Do you guys have a go-to first check for 'totally dead' gear, or do you just follow the power?

A customer's offhand comment about a 2015 laptop battery

They asked if I could just replace the swollen cell, not the whole unit, to save them money. It made me realize how many people assume parts are more modular than they are now. How do you explain integrated component design to folks without sounding dismissive?

Just saw a tech at my shop use a regular screwdriver on a tiny Phillips head and strip it

He was working on a Nintendo Switch and the screw was basically ruined. I keep a JIS #00 driver for those jobs now, it makes a huge difference. How many of you guys actually use the right driver for Japanese electronics?

A customer in Denver said my solder joints looked like 'cold oatmeal' and it stung

I was fixing a vintage radio and thought my joints were fine, but the guy pointed out the dull, grainy finish on three of them. I switched to a hotter iron tip and started using more flux paste, which made a huge difference. Do you think visual inspection is as important as electrical testing for judging a good joint?

Rant: Saw a repair shop in Tampa charging $50 just to look at a phone

Walked past a place on 7th Ave yesterday with a big sign saying 'free diagnostics' but a tiny note on the door said there was a $50 fee just to open the case. That's not free, it's a bait and switch. Do you guys think that kind of pricing hurts our whole trade's reputation?
