I am very saddened to see that literally no one has pointed out that this is the completely incorrect way to discharge a CRT. Your wall ground is not connected to the TV chassis ground, the chassis is two pronged and is isolated. The charge isn't stored in the flyback or it's anode wire, It is stored inside the tube. The tube needs to be discharged to itself, from anode button to the dag coating or the ground wire strapped around it. The Flyback cannot store a charge, is it simply only a transformer.
@@Cr1z4n63L The tube itself acts as the HV capacitor, hence completing that circuit with the grounding dag strap. Also why they will self recharge minorly if left disconnected
This video is a safety hazard. The method shown to discharge the tube does nothing. If the tube contained a lethal charge, it would still do so after it was connected to earth ground - with a single wire. The tube is discharged by connecting the contact at its anode cap to the tube's kathode - which is usually connected to the monitor's chassis. The point is to short circuit the tube - not to connect a single of its contacts to an external, unreferenced voltage potential (like earth ground). When making such videos, it's better to leave out such safety critical steps - but simply and clearly warn viewers to check out other descriptions of how this is done safely. This is much better than to spread such dangerous misinformation.
@@SciTyeTech hope this help.. i found my old tv is 10inch.. have a thick bazel i have to trim the the side bazel to fit my 14inch lcd laptop. My suggestion better find the size that fit the height because the width can easy be fit.. most hd screen wider than old screen. Lol, i just realized mine have speaker grill make my bazel wider than yours tv shell.. maybe you find some old lcd laptop or notebook that run xp or vista, windows 7 basic era most of use old aspects ratio
There was a time when the actual flyback transformer went to a high voltage diode and then to the CRT. In those days, the CRT would hold a high voltage charge which would usually be around 15Kv in color televisions. Those chassis’s were built of sheet metal and either had vacuum tubes or modules. Discharging an anode on these CRT’s required a screwdriver with a long shaft and a clip lead connected to the chassis. You would run the screwdriver under the anode cap until you heard the discharge snap. This is even when the set was discharged for hours. Yeah, I’m a retired TV tech.
I like to dig in my basement to look for broken electronics that I can scavenge parts from to maybe put something cool together One of my most recent tear downs was a old Dell latitude from the late 1990s running windows XP while I did get some cool stuff out of it such as a hard drive, Disk burner, screen and some other stuff I felt like I broke this laptop for a good reason because the battery made it slower and I also tore down the power pack I said I was glad I broke those but the truth is I wasn’t and the reason is I had a love for old tech and my mom bought it for me from eBay and I felt like I could have brought it back to life And normally when I tear down old electronics I usually end of breaking them or they don’t have what I’m looking for
Nobody ever desoldered all the components off a board. It’s such a waste. That design of a set was just before the advent of flatscreen TV’s which were not meant to be serviced by anyone.
When I was little I always had CRT TVs I had a Spongebob TV, a Diamond Vision TV I played on a old Windows XP Computer but for some reason now that I’m interested in Electronics I’m a little paranoid using one because I had a few in my dads garage and there’s a good chance some dust and sawdust got in there and I’m worried something would catch on fire considering the 27,000 volts in there Nothing happened though just some crackling noice and that’s it I’m 15 btw
That's cool that you are interested in electronics at a young age! I wouldn't be too concerned because the saw dust is not conductive and the high voltage connections are insulated. It would be the bottom of the flyback transformer that could be an issue. The connections are exposed but not dangerous, it will only shock you a bit. If it was metal shaving then maybe, but really likely. It would just cause a short and flip the circuit breaker before there would be an issue.
Hmmm, I think that some of those silver "capacitors" were not really capacitors, but crystal oscillators, although I might be wrong, because I can't see it verry clearly.
"This comment will be very, very useful". Just kidding, but I wanted to point out a few things. These sandstone and ceramic resistors are not necessarily "high voltage". A resistor's rating is dependent on the power rating, which is related to voltage across it. For example, only 10V across a 10 ohm resistor will dissipate 10 watts. That's a lot of heat and but hardly "high voltage". That white sandstone resistor is rated for 5W and appears to be 1.8K, so 95V across it will max out its rating. 95V is high voltage, but if that resistor was a lower resistance we'd be talking about much lower voltage. I'd advise against reusing electrolytics. It might be ok if they're tested, but they tend to degrade more than any other part with age and aren't very expensive new. I also highly doubt that large IC will be useful for anything. It's likely some sort of video processor specifically for a CRT TV. The three leg "capacitors" are more likely ceramic resonators. Not capacitors at all.
That's a good idea. I will probably do that next time. Why I did this in this video, is that I wanted to show how to safely teardown a crt tv safely and salvage for the components.
It supplies high voltage to the cathode gun to produce an electron beam that is manipulated by an electromagnetic field to produce an image on the phosphates of the screen.
Hi I am curious wondering if you could by chance help me fix my Philips crt tv? The model number that I have is 24PT6341/37. The problems I am having with the tv is the RF connector on the back has broken off. Secondly there is no sound on the tv either. The sound went out right after the RF connector broke off so I am unsure where the issue is as I am assuming that had something to do with the sound no longer working. Is there any way to fix the RF connector and the sound on the tv? Please let me know as soon as possible!
Worst video I seen, I came here to figure out how to remove the board on the tube, but once I seen how he took off the anode, I come to realize this man knows nothing about safty or CRT-TV

I noticed that too. It's like discharging a capacitor by connecting one lead to earth ground.

touch it lol its fun
Totally agree with you. But isn't there a capacitor inside the flyback?

U can use the tv shell for aio pc using old laptop.. i made one. But still working on upgrading the laptop built in speakers.
Cool idea! I just need to find the right size lcd. I originally thought of turning it into a fish tank or terrarium.

@@SciTyeTech oh ok! thanks for letting me know! 😁
this is so helpful for monitorhead cosplayers (which I'm studying up to get my parents to help me with lol)
You're welcome! That's a very cool idea!
Awesome, me too!!
Cool!
Just out of curiosity, how long did it take you to desoilder all the components from the PCB?
I would say it took me close to 2 hours.
Wow. Thanks for the reply!
@@SciTyeTech by the way Those blue components that you didn’t know what they were those are resistors that are high voltage resistors
Thats a sharp crt tv
Yes it is.
Hmmm, I think that some of those silver "capacitors" were not really capacitors, but crystal oscillators, although I might be wrong, because I can't see it verry clearly.

Nice hope the parts come in usefull
Most of them were.

i enjoyed seeing the guts of a crt tv
lol!! Very satisfying!
Very nice video 👍 on CRT TV teardown
Thank you very much
Dude! Why are you using your bedroom voice?
lol! Am I?
why not showing board??i dont consider it teardown..can you please addd circuit names
That's a good idea. I will probably do that next time. Why I did this in this video, is that I wanted to show how to safely teardown a crt tv safely and salvage for the components.
Very neatly arranged. You should open a parts ebay business.
That's an interesting idea!
@@SciTyeTech The local recycle shops should keep you well supplied.
Can you rebuild it?
I could, but that was not my intentions. lol!
What does the flyback do?
It supplies high voltage to the cathode gun to produce an electron beam that is manipulated by an electromagnetic field to produce an image on the phosphates of the screen.
@@SciTyeTech then what does the Circuit board on the back of the crt do?
@@SciTyeTech thanks!

HOW TO BUILD CHAKRAS FOR ALL
The giant screen makes me uncomfortable
I have one.
Nice asmr
lol! Thanks! That's just how I usually speak. I am always very calm.
lol this is the exact type of TV i have but mine has a seizure when i pull it up :/
lol!
@@SciTyeTech i put this on to try to find out why mine wouldnt open then i saw THERE WAS ANOTHER SCREW I MISSED AAAAAAAAAAAAAAAAAAAAAAAAAA
@@SciTyeTech actually mines a bit different
helpful, but why are you trying to seduce me?
Lol
Is there Red value with mercury
What do you mean?
What u gonna do with screen
I had some ideas of maybe lighting it up to glow in different colors, but I dropped it and it broke.
@@SciTyeTech oops
can i get the flyback. mine crt 21 inch has flyback issue.
Some of the capacitors look like Photo Flash Capacitors from a camera
Did you find some in that tv?
Very well detailed video btw!
Thank you! No I did not find those.
SciTyeTech oh ok lol some of them looked like flash tho
But still great video!
Amazing your are full of Amazing things Tye your a chef your a RUclipsr dang what els can you do 😂😂😂👍😊😊❤️
Thank you! That's so nice of you to say that.
Sci Tye Tech YW I mean what I say 😊
Why are you talking so quiet?
Don't want to wake up your parents?
lol! No, but that's just how I usually speak. I am always very calm.
