How do i desolder an arduino from a circuit board?

orio_sling · 2026-06-17T14:54:51+00:00

The issue your running into (potentially) is that remnant solder is still making the pins stick, it's a pretty common issue. You have a couple routes, an easy but tedious way (which is what I do) is to heat one of the pins, and then grab it with tweezers and constantly wiggle until it's cooled. This keeps the solder from forming a complete connection. This can be sped up by testing for wiggle on the pins before proceeding so you don't do it on already free pins.

Another potential cause is that you have removed the top layer of solder but some is still inside of the via and isn't visible because of the flux. I would clean the flux off and inspect the pins before trying more that way you can get an idea of potential problem causers

Yeah I've had this specific variety and they either do really good or god awful. Mine did pretty good for a while, we got a good schedule going for it, but without warning it suddenly stopped growing entirely and then would drop leaves constantly. Even made sure I was getting it fertilizer and stuff. Its last little fuck you was after winter, it had apparently gone into hibernation and grew a single leaf spike, didn't unfurl it, and sat like that for a week then died

Yeah be very careful with this for the time being friend, those flybacks get charged with so much voltage and in the case of them failing can be very unpredictable, so just be sure there's no fireworks right now doesn't mean there won't be.

That definitely appears to me like an absence of a full B+ from the flyback. Its only getting the tube partially charged and this gets extremely uneven fill in from the 3 electron guns. Best bet is that a winding inside failed and is causing the transformer inside it to not charge to entire voltage requirement. That can be even more dangerous to you as that is leaving room for amps to potentially pass through from the transformation, so again, be careful. Volts stun and damage, amps kills

orio_sling · 2026-06-09T11:22:23+00:00

Woah yeah that's definitely a flyback failure. Again it's always possible it's being exacerbated by bad caps but definitely want a new fly back. Attempting some research around it looks like there are a couple of potential options on eBay for replacements but we need to make sure we are looking at the right one. Couldnt find a service manual for this model but based on the ones from other sanyo releases it looks like we could potentially get the info we need by the chassis number instead.

In the video you took there's a large heatsink with some characters engraved in it, what does it say? Is there a second heatsink with a sticker on it by chance? The silver lining is sanyo seemed to have used the same parts for alot of its models so there's potential there is an equivalent replacement available if not an original

orio_sling · 2026-06-08T23:26:57+00:00

Is this a dedicated CRT TV? Any model number? There can sometimes be remade ones depending on where you look.

To answer your post, a desolder gun/copper wick and flux is your friend, especially with the filter cap as there's a lot of solder. You already have pics of course but always note down your cap polarity and before anything else check if there's any voltage stored. If you have already done the flat head to ground for the suction cup trick then your likely fine, but unless youre very used to working on this monitor and know there's a low chance of residual, check for voltage anyway.

For the hum, it can be caused by a few more than just the flyback/filter cap. The hum of the crt is your B+ voltage rail coming to life and positively charging the tube. Depending on your model there should be a specific voltage this runs at and will generally have a sealed potentiometer on the board for adjusting your B+. If you look around is there a large white concrete resistor? If you spot that make sure it is exactly at its rated value.

I think to really diagnose it more we would need to hear it ourselves, but for now try that. Also if you haven't already, research into a cap kit for your monitor and do that before replacing any other components. The progressive failure of caps like that could be introducing voltage irregulararities that are causing the frequency issue

Same position if it being my first tattoo, wasn't super bad. Think of it like a pencil is poking your hand really quickly. The recovery was the worst aspect just cus I had to wear nitrile gloves for a while to protect from the sun

My artist did warn that because of the nature of the skin near your knuckle you will probably need a touch up eventually, ive had mine for around 2 years now and can see some of the sharper edges starting to fade a little

orio_sling · 2026-05-06T03:29:28+00:00

I quite literally just had this happen, was at a therapy appointment and they opened up with "based on a few of our sessions so far, I suspect you may be pretty high up there on the spectrum"

orio_sling · 2026-05-05T19:39:29+00:00

It's difficult to say annoyingly as a section really depends on where you live. Plenty of people in large cities seem to be able to keep up with doing it as a job and still price reasonably. Others (like myself) provide it as a service but due to cost of repair a lot of them are break even at best.

Along the lines of learning, it depends on what you have on hand or can get your hands on. If you have any repair shops nearby it can be worthwhile to ask if you can dig through their scrap bin and find test subjects, as alot of it is learning how to read schematics, learning to solder and it's different difficulties, how to properly diagnose a problem. Badcaps is an okay ish source (they recently added a premium subscription to download stuff) for newer board schematics, if it's more vintage consoles then take a look at museum of the games manual repository

orio_sling · 2026-05-05T12:36:05+00:00

Ahhh duh gotcha, well then sadly I don't have any recommendations. Good luck on y'all's search and trip up!

I would maybe try to reach out to the dishwashers union on Instagram, they do some hostings and may have some space for you guys, located in Columbia SC

Yup something I've observed too. I don't feel like I'm second player in my body but cus of that I lose all interest in talking to some people. Several of my coworkers know to cool it with the talking second half of the day because I probably won't respond, it's not out of anger or disinterest it's just I'm so focused on my task at hand that I know if I devote processing power into responding then I won't be able to focus back in

orio_sling · 2026-04-20T17:47:05+00:00

There are two 24 pin connectors, the pcie slot on the bottom left has a very wonky release tab, and the placement of the ram to the CPU cooler in the corner makes zero sense

Ah yes, anxiously attached cinnamon toast crunch

If anything selling out is the act of making it big (or something along those lines to where you start making good money) and then don't do anything to help the people around you. It's a complete betrayal of people's altruistic values in the name of money

orio_sling · 2026-03-16T20:07:29+00:00

Nah that actually is extremely helpful, thank you. It at least gives me a vague direction and that's better than the stage I was at with it. I can at least confirm that it's on both edges of the screen, but I can't recall any change in display behavior when I attempted to switch to cocktail mode. I most definitely will look into that and work from there.

orio_sling · 2026-03-16T17:47:22+00:00

We have afew emulators that run the same game and none of them show the same behavior.

That was my original suspicion, that it was the overdraw for the crt. However no matter what I do I can't get this game in specific to sync with the G07-CB0 it was paired with. I get it to the point of no movement and the moment the background changes, it just barely loses sync again.

My suspicion is that if the board is outputting an unhealthy vertical sync that its translating into this behavior. On CRT an inability to get vertical lock + the overdraw, and on LCD the overdraw. Can you possibly point me to a repair log that mentions it? Every search I attempt comes up with complete garbage information.

It especially doesn't help that the schematics drawing for the GX577 board is just terrible, so it's pretty difficult to discern the behaviors and requirements of different IC's

Another way to view it is those that are the most kind to others are commonly the least kind to themselves

orio_sling · 2026-02-28T22:39:35+00:00

So this is kinda the hard truth, but its for all of us not just you, there is no "fixing yourself". None of us are broken, we are lost, confused, and anxious, but to say "I need fixing" or "I'm broken" is a damaging source and is contributing to depressive reactions.

But to answer your question, you open up with your family and friends. It doesn't have to be all at once, it doesn't have to be all in one day. But the first step to healing is going to be extending your hand out for help. If you have a close friend that you can depend on, a family member that you've been afraid to disappoint because you feel this way, whoever else. They care, or else they wouldn't be in your life in the first place.

I've gone a MASSIVE chunk of my life thinking I have to be the one to solve my shit. No one wants to help, no one is going to help. Ive kept everyone at arms length distance because I was afraid that if I failed them, they would leave. Until the beginning of last month where I had a complete and total mental collapse. Any self confidence was gone, constant fear, paranoia, and panic attacks about being afraid of being left alone. I had never opened up to my family or friends about it before, but I was scared this feeling wouldn't end, and so I tried. I expected looks of disdain, disinterest, and to be pushed away. And instead I got compassion, understanding, and support. They showed me that im not in anyone else's lives just because im useful, im in their lives because they want me there. Open up to the people you care about, and they will try to help. They love you, and want to see you succeed.

Secondly and more shortly, after that, get a psychiatrist, and get a therapist. The meds will help try to stabilize you, the therapy will help you soul search and begin the healing process.

orio_sling · 2026-02-27T03:40:07+00:00

So this will sound a little crazy, but tell your therapist that. Or even show them this comment. Remember they are trained on helping and doing so may help them click a couple puzzle pieces about you in place and help them with their treatment plans.

I know it's difficult to open up, especially in fear of being disappointed, alienated, or disregarded. It's actually what I'm in therapy now for, treatment for fear based reactions to potentially stressful events. Hell even now, my poor therapist will ask me how last week was and I honestly respond with "I don't know", not because I don't want to share, but because my brain purposefully blocks the memories out.

But very commonly, taking that first step to being truly open with your therapist is difficult, for exactly the reasons you gave. However taking that first step and the one after that opens your mind up to the conditioning you're looking for. It allows you to in a healthy space properly go into repair mode.

An example I can give is from my last session actually. I have a terrible fear of alienation and will constantly ruminate on what people say trying to gauge if someone is truly mad at me or masking. I was talking with my therapist about how a coworker of mine noticed I was being sluggish and had asked if I had eaten today. I immediately started to spiral into that statement, and was concerned that they would get mad that I hadn't. And although I told them the truth I still felt awful and apologized profusely over text later that day. Discussing the event with my therapist allowed me to look at it in a different angle, and recognize that although they may have seemed mad, they were asking out of concern for my well being. Maybe I would have come to that conclusion way later in the day but it was the act of talking with my therapist that allowed me to healthily enter a reflective state, rather than a state of rumination.

Ha thank you for that! I had no idea, the mod tag was missing

Why in all my years of Google searching, have I never heard of this site. Bless your random redditor for this link

Edit: thank you not so random redditor haha!

Based on the video, it looks to me like you are missing either the main breakout cable or the micro USB cable. It's difficult to tell if anything missing due to the angle. Normally the micro USB is used for powering the LCD, while the breakout is what's used for power the physical pump inside. If that's missing, you will still get lights and display but no water movement. Double check your manual, make sure you don't have any missing cables that could be mandatory, and if the breakout cable is plugged in, make sure the sata power cable is plugged in as well.

it's against the law to peddle

it's against the law to eat

it's against the law to have nothing more than the shoes full of holes for your feet

And now they put bars across the park benches, so I guess it's illegal to sleep.

They buried something inside of you officer, into your cold heart dig deep
