I was dreading fixing this old Sony TV from 2012 that kept shutting off after 10 minutes, figured it was a dead mainboard. Turns out it was just two swollen caps near the power supply that I swapped in 15 minutes for under $2. Has anyone else had a repair that looked way worse than it actually was?
I hit 50 repairs this month on a mix of old Xbox 360s and PS3s from my local Facebook listings. Started doing this as a side hustle in Dallas about 8 months ago, and I didn't expect to get that many so fast. Most of them had bad capacitors or disc drive belts, nothing crazy hard. Has your repair count surprised you at any point, or do you keep track at all?
Some user named 'fixit_frank' told me to always replace a bulging cap with the exact same brand, so I spent 3 days tracking down a Nichicon for an old monitor. Turns out any decent low-ESR cap would have worked fine and I wasted $12 on shipping for nothing. Anyone else run into bad advice from this sub?
Figured they were just overpriced toys for hobbyists, but after soaking a filthy motherboard from a 2010 receiver in one for 10 minutes it came out looking factory new. Anyone else have a tool they dismissed for years before finally trying?
I was fixing a busted power supply from a 2012 Dell desktop last weekend. The capacitor was stuck on the board like it was welded on. I cranked my hot air station to 400C and hit it for a solid minute. Nothing moved. So I kept going another 30 seconds and the whole surrounding plastic connector started melting. Learned that slow and steady wins with these boards. I should have used flux and a low melt solder first to break the connection. Now I'm out a connector and the cap is still half on there. Anyone else have a trick for getting stubborn through-hole caps off without damaging the board?
Last month my neighbor, who fixes old radios, told me to spray canned air upside down to freeze bad solder joints. I laughed and told him that's just going to spray liquid everywhere. Tried it on a cracked joint in my own stereo and it actually made the connection pop right out so I could see the problem. Has anyone else been given advice that sounded totally backwards but actually worked out?
I was trying to remove a voltage regulator off an old laptop motherboard with my 858D set at 400C and it just would not budge. After 3 minutes of heating, the solder still wasn't flowing right and I ended up lifting a pad. What temperature do you guys actually use for ground plane components?
Spent an hour scraping adhesive off a Samsung tab yesterday until I remembered to preheat the frame to 90C for 2 minutes before pulling the glass. Has anyone else found a specific temp that works best for different tablet brands?
Old timer at my shop swore I was making more work for myself replacing every capacitor I saw, and after chasing a ghost voltage on a Samsung TV for 3 hours last week I'm starting to think he had a point. Anyone else have a mentor whose advice you fought for years before it clicked?
My mentor told me to just crank the iron and watch for the solder to flow, but I cooked two $400 telecom boards last week before I caved and bought a $90 preheater. Has anyone else found that hot air alone just doesn't cut it on dense 8-layer stuff, or am I missing a trick?
I used to just dab at solder joints with a q-tip and 91% alcohol, leaving that white sticky film everywhere. Then a guy at a repair meetup in Portland told me to switch to 99% and use a stiff brush instead of dabbing. Anybody else find out the hard way that lower percentage alcohol just makes things worse on boards?
I was picking up a vintage amp from a retired broadcast engineer in Portland, and he told me he never replaces electrolytic caps unless they're actually leaking or dead. He said he's seen too many perfectly good 50 year old units get wrecked by people shotgun replacing stuff. Has anyone else ever tested caps before swapping them, or do you just replace them on sight?
Since I swapped to a 25W Weller for vintage gear, I haven't lifted a single trace or killed a cap in the last 40 repairs, has anyone else seen a difference swapping wattages for delicate stuff?
Been fixing audio gear out of my garage in Nashville for about 5 years now. Last month I pulled open a powered monitor I fixed in 2021 and saw the joints had turned into this crusty mess. Turns out I was using a super aggressive flux and never cleaned it off properly. Started scrubbing everything with 91% isopropyl and a toothbrush after that. Anyone else run into hidden damage from flux years later?
I just crossed 500 logic board repairs for phones and laptops, and I'm honestly shocked not one has come back defective. On one hand it feels like luck, on the other maybe my process is actually solid - has anyone else hit a milestone like this and wondered if it's skill or just good fortune?
I had a guy bring back a PS4 I fixed 3 months ago saying the HDMI port was loose again. Turns out I was using cheap lead-free solder from Amazon and not preheating the board enough. Switched to 63/37 leaded solder and a $40 preheater from Fry's and my last 8 repairs have held up perfect. Anybody else get called out on a bad habit by a customer?
Bought a Hakko FR-301 last year thinking it would speed up my board repairs. Spent $180 on it plus tips and cleaning supplies. After using it for 6 months on various through-hole jobs, I honestly get the same results with my $15 desoldering bulb for most stuff. The pump clogs way too easy if you don't clean it after every 10 joints. My buddy who's been doing this for 20 years laughed and told me he still uses a manual pump on 9 out of 10 boards. Anyone else regret dropping cash on hyped up gear that doesn't deliver?
The precise temperature control and steady airflow on the Hakko FR-301 let me replace a BGA chip on a laptop motherboard last week without scorching the surrounding components, something my old unit could never manage.
Went with the station to finally fix a pile of Xbox 360s with bad HDMI ports, and it's been a game changer for BGA work. Anyone have a favorite budget meter they'd recommend next?
I was fixing a vintage radio for a guy in Portland last month, and he said my solder work looked messy and could cause cold joints later. I mean, I thought my joints were fine, but he was right when I looked closer. Now I spend an extra minute cleaning my iron tip and using more flux before each joint. Has anyone else had a client give them a tip that actually improved their work?
I was watching a repair video for a Sega Genesis and the guy said over 70% of the failures he sees are from the same small surface mount capacitor, the 2200uF one near the power input. He said he buys them in packs of a hundred because he replaces them so often. I checked a few boards I have lying around from jobs, and sure enough, three out of four had that exact cap bulging or leaking. It's wild that one cheap part can take out so many systems. Has anyone else noticed this being the main culprit for a specific piece of gear?
Has anyone else had a tool that seemed like a splurge pay for itself almost immediately?
Had a client bring one in last Tuesday, screen was totally dark but you could see a faint image with a flashlight. Spent like two hours checking the usual flex cable, but it was actually a single blown capacitor on the backlight circuit, C7702 on the board diagram. Anyone else run into this specific fail point on the A2159 model?
I used to blast every board with my Weller heat gun for 30 seconds before even looking at it. Then I had a Samsung TV board from a job in Tacoma where the heat actually shifted a tiny capacitor and made a cold joint worse. My buddy pointed it out and said 'You're cooking the good parts too.' Now I only use it for big, shielded chips and check the smaller stuff with my iron first. Anyone else dial back their heat gun use after a mistake?
