I ran a Weller WES51 for years and thought it was fine until I borrowed a Hakko FX-888D from a friend last spring. After two months of repair work on circuit boards, the Hakko's temperature recovery was noticeably faster on ground planes. Has anyone else switched stations and found a clear winner for their daily work?
I was going through my old repair notebooks trying to find a trick for a Samsung power supply issue. I decided to tally up all the jobs I've done since I started doing this on the side a few years ago. Ended up at 512 completed boards, with maybe a dozen I couldn't save. That number just surprised me because I never set a goal or anything, it just happened. Has anyone else ever gone back and counted how many repairs they've actually done?
I was going through a 1980s stereo receiver last night and decided to actually measure the ESR on the power supply caps instead of just replacing them blindly. Found out three of them had ESR values over 10 ohms even though they looked fine and tested okay on a basic capacitance meter. That detail came from a forum post by a guy named Mike in Austin who specializes in vintage gear. Has anyone else found that the physical condition of old caps can be totally misleading?
I've been using a cheap heat gun from Harbor Freight for years to shrink tubing and remove components. Last week I borrowed a friend's $60 Weller one and it hit temperature in like 20 seconds instead of my 90 second wait. I looked up the specs and mine is only 800 watts while the Weller is 1500. All those times I thought my solder joints were bad were probably just the heat gun being too weak. Has anyone else had a similar experience with a tool they thought was fine for years?
Pulled a blown capacitor off a GPU in under 2 minutes flat without scorching the board. Has anyone else seen a big jump in success rate after upgrading their gear?
I had this Dell U2412M that kept flickering after 10 minutes of use. Tried replacing the power board first but that didn't help. Turned out it was a single bulging 1000uF 25V cap on the logic board near the ribbon cable. Now I check those first and it's cut my repair time way down for that model. Has anyone else run into this issue with the older Dell U-series monitors?
Spent all afternoon swapping out a trackpad on a 2015 MacBook Pro only to realize the old connector wasn't fully seated, cost me an extra 4 hours of head-scratching and a near trip to the dumpster, has anyone else had a repair drag out because of something this dumb?
I finally broke down and bought a Hakko FX-888D after using a $15 iron from Amazon for like 3 years. The difference in heat recovery alone is insane for doing THT joints on old boards. First project with it was fixing a dead power supply from a 90s JVC receiver and it took me half the time. Anyone else notice a huge jump going from budget gear to something mid-tier?
Last Tuesday I was fixing an old laptop in my garage and tried to reflow the GPU with my cheap heat gun. Got too aggressive on the low setting and melted the plastic on a RAM slot next to the chip. Board was dead after that, wasted 2 hours and a $30 part I ordered. Now I always use kapton tape and aluminum foil to mask off stuff, lesson learned hard. Has anyone else fried a board trying to save one with heat?
Had this lady bring in a 55 inch Samsung last year with a straight face telling me her TV was possessed. Said it would flicker and show static faces at night only. I asked when it started and she said right after her nephew 'plugged in some game thing.' Took me about 2 minutes to unplug the HDMI cable from her Xbox and boom, picture was perfect. She didn't believe me at first, kept insisting I needed to bless it with holy water or something. Charged her $40 for a diagnostic fee and she actually paid it and thanked me. Ever had someone argue with you that the easy fix wasn't the real problem?
Was down in Austin last month helping a buddy clear out his dad's old shop. Found a Yamaha CR-620 with no sound output. Guy who used to run the place had a note taped to the bench - "check the relay first, not the caps." Popped that relay open and sure enough the contacts were just dirty. Cleaned them with a file and it fired right up. Anyone else run into dirty relay contacts on 70s gear?
I used to think a good soldering iron was all you needed for fixing electronics. Then I tried to replace a tiny capacitor on an old motherboard last month and melted half the traces. Swapped to a $40 hot air station and finished the job clean in 10 minutes. Now I keep both on my bench but the hot air gets way more use for SMD stuff. Has anyone else found they grab the hot air more than their iron now?
I was going through my logbook for the shop here in Tucson and realized I just crossed 500 repairs for 2024. That's more than I thought I could do in a year, especially since I only work on micro soldering and console power issues. A lot of those were PS5 HDMI ports and Nintendo Switch charge ports, which used to take me forever. Has anyone else tracked their numbers and been surprised by how much you actually get done?
Couldn't tell if they were being hopeful or just cheap, but do you guys take the time to explain bad panels to people or just hand it back and move on?
Bought one of those cheap digital stations thinking it was a steal, but the tip temperature was jumping around so bad I lifted a pad on a 1978 Marantz. Has anyone else had luck with the Hakko knockoffs or should I just bite the bullet on the real thing?
I've been fixing circuit boards in my garage here in Dayton for about 3 years now. Last Thursday I pulled a failed power supply from an old Sony receiver and realized it was number 500. I just started counting for fun after a friend dared me back in 2021. This one had a bad regulator and took maybe 20 minutes, but it still felt like a big deal. Anyone else keep count of their repairs or am I just weird?
Started acting up last Tuesday where the screen would flicker then shut off after 10 minutes. I was about to call it a bad panel until I checked the secondary side of the PSU under bright light. There was this tiny bulge on a 1000uF cap that I almost wrote off as glue residue. Replaced it and the thing fired right back up. Anyone else run into caps that hide their failure like that?
I was fighting a stuck capacitor on an old TV board with my cheap plunger pump for 20 minutes with no luck. Dropped the cash on a Hakko desoldering gun, popped that cap out in 5 seconds flat. Anyone else find that spending a little more on the right tool saves way more than it costs?
Honestly, I bought 500 of these cheap caps from a surplus place in Detroit and half of them failed within two weeks on the bench. Now I'm stuck redoing a bunch of power supply repairs for free. Has anyone else run into fake caps from that supplier?
I was at a virtual meetup for the Midwest Repair Guild and one of the presenters said that. He showed a photo of a blown capacitor he replaced because he "always used 105C rated parts" without checking the ripple current specs. It made me realize I've been doing the same thing for years on old power supplies. I went back through my last 10 repairs and found two where I probably could have avoided a failure by following the datasheet closer. Has anyone else caught themselves relying on what they've always done instead of what the part actually needs?
I was cleaning up my bench after a long job and just out of curiosity I added up how many caps I've swapped out since I started keeping track back in 2018. It came to 1,043 exactly. That number kind of hit me because most of those were on LCD monitors and old motherboards where a bad cap was the only thing wrong. It made me realize how often we toss stuff that just needs a $2 part. Has anyone else ever added up a specific repair they do over and over?
Some old timer was telling the clerk he never uses flux on board repairs because 'it's a waste of time.' Then he showed a pic of his last joint job with cold solder all over. Changed my mind about skipping flux on those tiny SMD caps. Anyone else seen bad work from skipping the basics?
I just realized I swapped out 500 capacitors on various boards since I started keeping track three years ago. It surprised me because I always thought of myself as a general repair guy, not a cap specialist - has anyone else noticed a big number like that sneak up on them?
I was reworking a laptop mobo from a 2017 Dell XPS 15, trying to remove a bad HDMI port. Set my hot air station to 400C like I always do for big components, but I guess the shielding on that board held the heat in too long. Popped a nearby ceramic cap and had to spend 2 hours tracing the short. Learned I need to preheat the board to 100C first and drop my air temp by 30 degrees for dense areas. Any of you guys use a specific temp curve for multi-layer boards?
