- Опубліковано 29 чер 2024
- This Pandora's Box DX 9800 is faulty and appears to have no power. The LED lights come on, but there is no display, and there's no sound coming from the internal speaker.
Let's see if we can work out what's wrong with it and FIX it!
Hope you enjoy!
Steve

Sometimes Dave.. you just gotta go with the reflow....
😂
....... get out
@@hteekay Nope I'm here all week 😁
I will
If a short disappears and turns into a rising resistance, chances are your multimtr (sic) is charging a cap somewhere
I'm glad someone else said this. Multimeters inject voltage and small current into a circuit to determine the readings. This why it is hard to determine the readings you are seeing without knowing what they are supposed to be. Inductors will always show as low resistances as they are designed to filter/condition current, when used in conjunction with a resistor and capacitor, they create a frequency filter.
Yip.
You make these calls and second guess yourself thinking it was luck but you are a very intelligent guy and you have learned so much over the years you need to give yourself more credit! I do love how you stay humble tho. Such an awesome guy!
@dudewhoareu
Yes, well said. Steve is one awesome fella, but just needs a bit more confidence in himself. "Can I Fix It", 9 times out of ten, he can. Unless it's one of those disgusting "blob chips" or a part that is not obtainable, but that would beat all of us.
C'mon Steve, YOU CAN KICK ASS AND FIX IT DUDE.
Thanks for your comment Sir.
🤜🤛🫡🫡🫡🫡🫡🫡🫡😊😊😊😊😊
There's no resisting a zero ohm resistor! Your face when that worked should be your channel icon! Great honest reaction
Spectacular fix! 😊
Regarding the short/no short;
You might be charging a capacitor with your multimeter.
(Think of the multimeter as a very small bench power supply.)
So the capscitor flows back and makes it look like a short for a moment
Thats one of the many reasons its hard to measure things in circuit.
Just want to thank you for your videos. It has been a source of inspiration for me for a while. I've been fixing some stuff like Game Gear, PS1 or NDS and your videos taught me a lot.
My brother is currently dying at the hospital after a tough fight against leucemia. Your videos are the only thing I bear watching tonight while I can't sleep
Steve. I don't know where these beats come from but I love them. I was bobbing my head at work subconsciously with this video on in the background. I forgot I was listening to a song about your viewers for a min.
"I'll probably do more harm than good. [ .. ] Let's reflow it." :D Yay! It worked!
Couldn't resist! I thought it was worth a go!
@@StezStixFix i know how it feel , did that on my xbox one x retimer chip did work for a few months till it die again. but on xbox it's a common issue, i do the same freaking ask myself a lot while doing electronics repair/projects can't help myself but try. LOl good video cheers
@@StezStixFix Was it a zero ohm resistor after all? /s
@@StezStixFix Almost as hard to resist as a 0 ohm resistor
Couple of things to remind yourself in situation like that;
It was already not working when you started.
If it is not working at all, you can't make it work less.
Man Steve, you are getting good at repairing this stuff. Your videos are an anticipated highlight of my weekends. Keep'em coming man. I love it.
Steve, you look absolutely adorable with this shirt! It suits you ☺
You want to know something? When I first started watching this channel, those patreon songs were such 🔥🔥🔥 that I thought you were paying a musician to make it for you.
It probably took at least like maybe around 10 videos before I realized
it was you 😂
That irrepressible smile at 21:49 was so sweet and defines why we do stuff like this
Brilliant fix Steve well done glad the reflow worked 😊
Nice job Steve!😊
That was the most luckiest fix I ever seen. so awesome Dave I love it ❤🎉 congratulations
Way to go Steve! Yo man, a win is a win. Truth be told, I'm always rooting for ya. Can't wait for the next one.
That is some impressive work there, Steve!
Love you videos - the surprise on your face when things work is great….. well done, I’d still replace the internams with a pi5 ❤
You must have the magic touch steve well done 😊
Trust in the flow Dave!!!
Nice work Steve ! Get in !
EXCELLENT WORK!!!
excellent work as usual steve
sometimes it can be simplicity even when its not obvious sometimes stuff need reflow when you don't even realize it
hahahaha we all smiled when it worked . very nice steve :)
Love you video steve make my day keep up the good work
7:07 your multimeter has to inject voltage and a small amount of current to the system. this can charge up a few capacitors. and resistance is technically a voltage drop. the resistance of your multimeter is pretty high, so there is just a little little current when measuring a resistance. so the multimeter is reading the voltage drop, that's available in the circuit.That's also the reason why often measured resistances go up and down while you're reading them.
9:05 Coils: coils are frequency dependent. Just measuring the resistance is just not always enough. If the leads inside a coils are touching, you still read 0 Ohm, but the frequency related resistance is not the same as before.
You are the hero of resistors marked zero.
Wow, a bad BGA solder! You don't see those too often, knowing how the factories work! Great repair!
Do this as a test, it should explain why you get continuity that disappearsd
Grab a random capacitor, test for resistance on lowest range, you should see a near short that changes resistance the longer you are connected, now reverse the leads, you'll get the same
When you test for continuity, you are charging capacitors, leave the leads on longer if it looks like a short when testing.
You need an LCR meter to check coils, prferably out of circuit
you could tell he was so surprised he didn't even say "GET IN THERE!"
Good job dude.
Seems like a crawler went under the chip and fried itself, the body parts shorted something until the reflow cleared everything.
A literal bug!
@@technoman9000 Finally, someone used 'literal' correctly on UA-cam.
Another awesome video. Always entertaining and love how excited you get when your fixes work. Ha!
I see your videos from around a year now.. I love you fixing the "stupid" things 😅
Excellent job young Padawan.
Loving your pc background. Instant nostalgia
that was a great outcome for sure
It is fuseless to resist a zero ohm resistor ...
Love your videos... Thank you for your content...
Good job
Believe in youre self more pal we all love youre repairs keep it up pal thankyou 👌
love the nirvana cover.
I celebrated with you after the reflow! Thank you for another great video.
Some more of that fibrous material came out when you re-flowed the main chip. 20:40 - right hand side of the chip.
Best outro. Ever. 👍
@ 11:44 - it is a measure of inductance, 2R2 means 2.2uH (micro Henries). The resistance across the coil will be very small: the only time (!) the resistance is important is if the coil has gone open-circuit (high resistance).
You the man 😊
Must be tempting to see if reflowing like that would fix some of the other projects you've had to shelve in the past. Reflow compilation video? :D
Can I get a _RE_ flow! ...sorry.
Snatches victory from the jaws of defeat once more 😂
well done
9:52 The disappointment on Steve's face with his own puns cracked me up. 🤣🤣🤣
nice pandora box😊
Today's rap was above par my friend! Good one! 👍👍 Fans in Canada.
Nice.
Another good fix there Steve 👍 - Stupid Pandora Box 😄
13:04 During a lot of time I thought you were saying "let it solder" instead of "leaded solder" as a joke, cause english is not my first language. I think I'll continue to listen to it as "let it solder" if u don't mind 😂. Fantastic job!
"This thing is so big, I dont know how I am going to film it...." - Glad you did. Ta! I'm off to reflow all of the things..
Love the shirt!
Love this guy 😂
nicely done, sir. I strongly suspected the HDMI input myself, mainly because we didn't see you inspect it I guess. Glad it's working though, those pandora boxes are some fun cool things for portable head-to-head arcade goodness.
"Take that Marian" - another classic StezStix Fix quote!
The battle continue.
A nice long video.... I love it when they are about 30 mins long :)
Nice
Love the "Phatt Island wharf" background on your computer.
That’s a mighty fine shirt, sir!
11:40
xRx values are in micro Henries (μH)
Three digit values are in nano Henries (nH) or micro Henries (μH), depending on manufacturers choice
First two digits are the value
Third digit is the multiplier (or number of zeros added to the value)
If there is an R, its acts as a decimal point, and there is no multiplier
Examples:
472 = 47*102nH = 4700nH = 4.7μH (Coilcraft)
472 = 47*102μH = 4700μH = 4.7mH (Bourns)
4R7 = 4.7μH
7:10 Likely a capacitor charging up off the meter..!
Take the win Steve :)
Short no short, charging a cap but is usually visible or switching on a MOSFET so leads the right way around Sir!! Inductors (coils) basically are a dead short at DC so hard to measure unless they are open but at AC its another kettle of fish, you would need to test at about 100 Khz AC. Resetting the trans optical wave differential oscillators time vector circuitry using heat was a cracking idea !.....cheers.
Steve, best I remember and I might be wrong but when checking coils, you need a meter that reads henry's and micro henry's. Coils are like that wire you use to make jumpers it has a coating on the wire that makes up the coil. Often times, they get hot, melt the coating and dead short. Using a meter that has henry's on it might help you. Idk.
stupid.... box! excellent repair
Battle Continue! 😎
Haha 😅
Well done. The only way to test inductors properly (in my opinion) is out of circuit (unless you have a schematic or another device to compare it, you never know what else is connected). Continuity (not open circuit) using Ohms etc, inductance (shorted turns etc) using an LCR meter.
Now reflow the tv!!! Another great video brother
haha another great vid ,i actually have one of these and they are great 10000 games on it but i think there’s lots of doubles ,and 1000s ive never heard off just fillers me thinks anyway nice 1 keep this great content coming please you crack me up 👍
Its a good job King and King rhyme Steve 😂
Stupid box indeed! Great fix!
Nice. Trust your instinct.
I honestly depends on these videos for my sanity, thank you. Hate the adverts though but hey ho. I've bought loads of what you use to do, I have no idea what yet lol
I always think with reflows, it's the memory chips nearby that get the benefit. Worth a shot either way. Nice
Haaaa fo short, bazing! Great vid!
Nice haircut!
That’s crazy, it was a good idea replacing the cracked coil anyway but a reflow working was a cool fix.
awesome. i would glued a cooler to the chip, preventing it from getting to hot in the future
Wherever you see a small inductor, with a small black IC nearby - that is a power supply for one of the power rails. You should get a good steady DC on one side of the inductor. The other side will have rapidly switching square wave, which might show as DC on a multimeter. Better to look with an oscilloscope.
absolutely love your content! You’re an internet gem!
There's always hope in the Pandora Box.
I know your Huapar broke and youse fixed it. Good fix vid that one too btw. I want one as the equivalent Flir is ridiculously higher priced (they aren't worth it imo) but the price for the Huapar has moved further north since your fixed-it video. More like £360+ after vat.
YAY ! 😁
Hey man, great fix! Are you sure that replacement coil fits under that heatsink? The main chip might be overheating after a while for not making appropriate contact.
Here's a funny story on reflowing chips. About ten years ago I had a coworker ask me if I could fix his laptop. I told him I'd look at it and see what I could do. He tells me it doesn't show any signs of life. Also he tells me that if I fix it, don't look at his pictures because he has nude pictures of his girlfriend. I asked him why would he even tell me that because I wouldn't have looked if I didn't know that bit of info. He was convinced I wouldn't fix it. Long story short I reflowed the Southbridge and it came to life. I brought it back to him and he asked what he owed me. I told him it's free of charge, and by the way, you're a lucky man. 🤣
Big bottomed coils, they make the rocking world go round
19:05 it’s a spiders leg, you were bending its knee to do a continuity test! 😁
Recomend to add termal pad to the heat sink ! Or update the heat sink !
Double Dragon. I remember that from arcades. Two dudes fighting through the streets in coop.
Oh my gosh
Really like you top
If in Doubt a Reflows worth a shout
Brilliant!!
When u soldered coil, did a little dance, made a little love, get down tonite.
You should’ve checked if the rock chip was still getting hot or whether it was running a bit cooler than 37 degrees.
