- This scope stopped powering up at some point. The motherboard was found to be at fault. After some attempts to troubleshoot the motherboard, a similar board was picked up on eBay for a reasonable price, which brought the scope back to life.

Great repair.
At one time Gateway had a tool on their service discs to write the splash screen file. I recall reversing the file structure to make humorous splash screens back in the day.
Thanks for the video. Nice to see some video tear-down on these popping up. I've been wanting to change mine to a sshd but never get the time to sit down and try and get it done. If you do yours, I hope you make it a video.
Excellent repair and "never give up" attitude. Also your audio is excellent!
Nice work, I would fully recap the original motherboard and see if that brings it back to life.
Great fix as always! You give me confidence to attack complex systems like motherboards, I might have written this off once I realised it wasn't the PSU or the easily swappable components...
Epic troubleshooting and repair!
Great work. And a great addition to the lab.
I always enjoy your videos.
A very pragmatic approach to repair.
You're the best.
Great analisys and repair.... As usual!
Great repair! In the models that came after (7054, for example) the bios is a special one: it was good to learn that you didn't had to swap them ;)
I have one of those. The sata cap is bulged, waiting for the new one in the mail.
Congratulations for the repair.
Good persistance in sleuthing. Thanks for the look.
Wow. That was extremely impressive!
Awesome repair job!
Excellent work! A good update is coming
Nice, I love saving these old Tek scopes. They are still useful and better than becoming ewaste.
Another outstanding video. You've been online for over 7.5 years (as of Nov 2021), yet you have only 10.4k subscribers. This is a crime! You deserve many, many more subs and views. What can we do to correct this situation?
Nice one ! Отличная работа!
It put up a fight but tenacity won the day! Great result with ultimately better performance.
a followup is coming
Nice job. Thanks for sharing.
Awesome as usual
Smart way of trouble shooting. 👍👍👍👍👍
Great job
Nice rising from death..
Good idea to backup hard drive!
Intel Desktop board inside was a surprise.
For old dead board - I, usually, start with CPU power phase transistors measurement when power supply goes into protection mode.. By symptoms, looks like ground side mosfets is shorted to ground (This is good scenario, because, when positive side blows out, CPU, usually, dies from direct 12V power)..
Great job thank you 🌹🌹
Nice, this was actually pc repair :)
Fantastic! 👍 👌
Nice video, thanks :)
Эх, до чего же красивы всегда высокочастнотные узлы и элементы.
if the software works with windows 2000 it should work with windows xp as well , so u could have just cut the io shield and upgraded this to a 775 motherboard , those are much cheaper , newer and more reliable than 487 boards. i had so many 487 boards die after 10yrs of use but 775s are going strong even after 13yrs. a core 2 duo or quad would be nice and unnecessary upgrade for this
For desoldering huge components with big ground areas like this USB connectors i recommend use the Rose metal. It's melting point about only 95 celsius and using completely reduces overall temperatures and make desoldering much more easier.
Прикольно. У меня плата немного другая. Кондеры по питанию проца вздутые были, но не все. И по питанию рядом с северным мостом один. Видимо производитель этой платы экономил.
Great video! So the fault is on the PC board, I can see it has a buzzer, so if was one of the components the little speaker would indicate if RAM or CPU is bad but the fact that it shuts down instantly resembles a short. These caps close to the Vcore... oh, God I hate these things.
Nice repair, Try starting the old motherboard without the p4 plug (4pin connector) closes to the cpu, if it stays on it would indicate a fault on the CPU mosfets, The RAM is DDR 1 not DDR 2, Those boards do have a lot of faulty caps, Old AMD fan should work as an replacement fan they are thinner fans. Great repair video👍👍👍👍 for dual DDR it needs to be in the two white slots
Yes, DDR (without a number, but often mentioned with frequency like DDR266, DDR333 or DDR400). I don't think I said DDR2. I know about the proper slots for dual channel configuration, thanks.
@@feedback-loop DDR266 DDR 333 DDR400 is all DDR1
@@AnonymousRepair It is called DDR1 retroactively. At that time, before DDR2, there was no number at all. It was called just DDR or with frequency appended.
@@feedback-loop correct these days everybody calls it DDR1 😂
yeah clone it! great job!
Great recovery for a nice old scope. Not keen on Microsoft run test equipment.
Thanks In Advance...!!! ;)
If you can make a video about the cloning would be amazing, i could not find any satisfactory help online, of cloning bootable HDD. Thanks for the amazing Video! Love your attitude. I would have probably drilled out the rivets of the bracket ;)
I prefer less invasive approach if possible.
@@feedback-loop true, but changing the motherboard is also ;)
Might as wel change the CR2032 battery, it will go eventually :)
Any chance that you may go back to the old motherboard and extensively clean it with alcohol? It does not make sense but it worth a try maybe!
Uau! what a repair! congratulations!!!! Another example that a bit of luck is always needed in any activity and even in life!!! If I were you, I would have been TERRIFIED at the moment the system was asking for drivers... Cloning the HDD is A MUST to recover this simply fantastic machine in case of another fault in the future. Do you think an SSD could do a better job?
Did you run a POST Code test using a card or checking LEDs on that initial board? It might be related to the BIOS rom
Nice repair. "Any testing is better than no testing." Agreed. Yep, always recap, as maintenance, since you have the device open.
You can buy an assortment of 5 different size desoldertips for the Sx100. They are all very usable sizes and for 99% of the time they cover everything you need
I have a few, but not that large
You solved that the way I would have solved it.... like a computer technician. Look for a working substitute part first.
Very interesting repair. Re-capping that unit will keep you busy for a while. Expensive scope with Chinese power supply. I think I would complain to Tektronix. They should be including their own supply.
Artesyn is of the world's top producers of power supplies. They would had not used them if they didn't make a good supply.
Can you desolder the bios on the original motherboard and dump its contents? Id like a copy.
To bad these old oscilloscopes depends on an old outdated OS to work. Will it Even accept to boot from SATA without additional drivers?
How does the scope communicate with the PC? Through a PCI card?
PCI - have a look at 3:28. It's not a card as such - the whole main board of the scope mates directly with the PCI socket on the motherboard.
on the original board, replace the ADP chip. I repaired the Intel board in my Lecroy Wavepro (it was a very similar board to this with a very similar 4 phase VRM chip but different part number) and the chip was dead as in yours. I had to buy it on ebay from china but it worked.
I have already placed an order
nice fix yea it would deffinatly bennefit from a ssd
Is the shure slx there for repair? :)

And this one about a handheld transmitter as well. It says PGX, but it uses the same board as SLX (just LCD display is not installed) ruclips.net/video/-APbI_hSflA/видео.html
Coincidently I've got 4 dead motherboards here I'm trying to repair - lol -.
If it's SATA 1 it's only going to be 150, not much faster than PATA 133, and most vids I've seen don't show much improvement with a SSD. If you see a difference I would like to know, because I would like to SSD my old 478 Pentium - I think it also needs caps because it doesn't start sometimes. lol =
I have seen night and day differences by changing to SSD in a bunch of really old machines. Even if the throughput is not much different, the seek time or lack thereof makes a huge difference in booting up the OS where you are reading hundreds of small files. Most of the machines I've done this on are industrial computers for CNC machines, so once loaded the disc is not used much.
@@RambozoClown Are these PATA IDE or SATA1, or something better. It's hard to find actual results of before and after, but I remember Defpom doing one and he said it wasn't much better. I guess I can get a SATA2 to PCI card and SSD it.
@@SidneyCritic I've used a mixture of PATA and SATA1 even some slow SATA to IDE converter boards. While the data transfer speeds have been the same or worse when moving large files, the time to boot Windows NT or 2000 is often cut in half or better. It all depends on what your workload is.
It all comes down to file size and latency for the HDD -> SSD conversions. Just about all of my computers (and some test equipment, looking at you, 16702B) have been converted over to SSD, and the speed difference is incredible. Loading an OS, especially an old NT-based one has many small files scattered across the disk that the head in the HDD has to seek and read. SSDs do not have this problem, and that is arguably the biggest speed increase.
I've never really run a benchmark across the different storage mediums and data transfer speeds, but I would say everything is better overall, with the most gains seen in random read/writes, which is very common, and lesser gains in sequential read/writes as the head does not have to move very far in the HDD.
@@davidstech1445 I don't really need the exact numbers, just that it feels considerably quicker, ie, faster boot, more responsive. I've done SATA2 SSD and it's a massive improvement, but no SATA1, so I'll have to defer to your experience with PATA SATA1.
was the battery in the original board any good? I have had instances in the past where a bad battery prevented the motherboard from booting.
the battery is fine
*GOOD ... IT IS WORKING.. IS A COMPUTER SO MORE RAM "MUST BE OK" AND "SSD" ..*
*AS A COMPUTER A "CPU" MUST ALSO BE TO "UPDATE"... (THEY DO STRANGE THINGS)*
*AND MANY TIMES ..THINGS WE NEVER "UNDERSTAND"..*
*BUT IT MUST "RUN" WITH A CPU WHO HAS.. (MORE CACHE).. 128 ..IS VERY LITTLE*
*HOPE YOU "HAVE" A BOX WITH "OLD CPUs" 100% ONE "WILL" WORK*
*GOOD LUCK)*
i know you can fix this
Hey, could you please tell me which driver you had to reinstall for the front pannel? my wont work and i am not sure wich driver i need
I put it in slow motion so you don't fix it that fast
My apologies that was a tough one
Лучше бы ты по русски озвучку сделал. Мой комп по субтитрам твой английский не понимает.
