CRT Safety - The Consumer TV Version - Cathode Ray Tube

[@ridleycampbell2518]

this rocks. I've been using CRTs for a while now (video game tournaments) and i've always wanted to learn more about how to fix them or repair them!! I have zero experience and a well explained & properly cautious video like this feels like an amazing place to start. Love all the safety tips!!

[@PatricksRetro]

Thanks so much for this video Steve! I just took a small CRT out of our basement that has not been used for 15 years and wanted to do a recap before using it. These safety procedures were exactly what I was looking for!

[@brahmdempers1005]

U can also add that dust can conduct static electricity and cause mayhem in electronics .Sometimes just dusting the tv inside at the back that had alot of dust buildup,can fix a faulty tv.

All color TVs can be modded for RGB, the tube needs to take RGB at some point either way.

@@Eddies_Bra-att-ha-grejer Yeah, they all _can_ be, but if the TV's own circuitry doesn't handle its signal in RGB before it's sent to the tube (OSD, PiP, CCD, etc.), that makes the RGB mod considerably more difficult and less worthwhile.

Wow! I’m so glad this video exists. I want to clean out a 1990 13 Inch crt I own. It works fine but It gets a bit of a gross smell after about 2 hours of use. I don’t know if it’s just because of all that dust or something else. But I want to see. So this is very helpful.

[@qmangillett]

It's funny to me to see certain things like no potting around the anode just a rubber cover. I test these everyday at work and that's a crazy looking coil compared to what we use. Of course the crt's I test are used in aviation so things are going to be designed alot differently

[@trond-ivaringebrigtsen2077]

A bit over the top on safety there, I worked for samsung making theese beauties, our production lines spat out 3,5 mill a year and I was responsible for dynamic purity/static convergence. A tiny jolt of 50-60k volts is nothing to fear for normal healty people, there is no wattage behind it, so just a tiny jolt. Keeps you awake and productive :)

[@H4RDSTYL3RAV3R]

Beautiful. Really great video Steve. Very thankful for you.

[@RetroTechUSA]

[@KittyKatKya]

The chip you were pointing out, likely branded SEC, is actually the jungle IC for the set, with the micro controller responsible for the OSD being up towards the front of the set underneath the tube. No way to tell from just the video, but if it's labeled "KA2163", I can say without a doubt that an RGB mod is doable.

[@RetroTechUSA]

Thanks. Yes you are right. That bigger chip is the Jungle IC. It also has the 2nd chip that sends in the OSD Blanking so it's a go for RGB!

[@spvillano]

If you're ever going to mess with an old CRT based analog TV, first get an isolation transformer. Most had the chassis ground tied to the neutral of the AC input and if your home is miswired, you'll have full mains voltage on the chassis ground. The other important thing is the one hand in the pocket rule. One hand on a circuit, the other in your pocket. Lest you have one hand on a ground and the other touches something high voltage or worse, mains current. Working with the CRT deflection, second anode or video drive circuits, no, those would be in person teaching. Too easy to get bit and damage something.

I got an unused RCA CRT fresh in box, unfortunately it decided to crap out after 1 short use... I guess the capacitors were old even though they weren't used.

[@jagmarc]

CRT bench repair techies used a pair of long-blade screwdrivers to discharge the anode. Holding them by the plastic handles of course and poking them in the right order. If hear sparks then it's done.

[@welcomeaboard69]

I've got an old crt that's been powered off for years. Im assuming I don't need to worry about discharging the unit and being shocked. Now I'm in Australia on 240 volts. I doubt the procedures will be any different from what you've shown. Please let me know if I'm wrong in my assumptions.

[@peterk1837]

I have been staring for about an hour at the focus/screen nobs that seem to need adjusting. Too scared. I made the mistake of googling it, and everyone is fearmongering. I have 1000v screwdrivers with plastic handles, or am prepared to use a shaved wooden chopstick to turn them. Still scared. I see you do it by hand and am so envious. I would love to go on a course where I can have someone at least look over my shoulder.

[@NeverSuspects]

alot of newer ones have resisters that drain the power when it isn't turned on, you can just use a large resistor clip one end to the metal frame or ground and then use some insulated stick to slide the other clip under the cap and let it drain through the resistor as that will not produce any arc and take a chunk out of your screw river.

[@ViliamJakubek]

I have never used gloves 🤣. Oops... once left a screwdriver in the anode when discharging. Turned it on and remembered then to take it out.

[@ВСЖМєсногоДеда]

hi Retro Tech! i've got this crt monitor with mitsubishi Diamondtron tube. the image is good and clear but it heats too much from the top, buzzes and smells) so i decided to take the cover off and blow out some dust. there was a lot of it. but what bothers me is the red circle where anode enters the tube is in black sticky substance and i don't know if i could just wash it off with spirit. i don't know if its an Aquadag, but graphite layer's visible sharp margins are 5 cm away from the red circle, so i think it shouldn't be there, on the circle itself. So, can i just clean it off? you will not be responsible (i mean morally) for any advice so please don't be cautious :) Sorry for long text and bad english )

[@patricknoel9096]

So clean inside the TV. Gave someone the excuse to help the people crawl out

[@eletro_doc9529]

One thing to keep in mind is to ALWAYS attach the draining cord to the chassis BEFORE trying to discharge the tube, otherwise you will receive the discharge yourself. EVEN if you're holding it trough the plastic part of the screwdriver because there's too much voltage. Might seem dumb, but when you're tired and frustrated about some defect it's easy to forget about it.

[@n646n]

It's impossible to get shocked if you're holding it with the rubber/plastic part of the screwdriver. That's not how it works.

[@eletro_doc9529]

​@@n646n A general screwdriver plastic part will insulate at most 1000v. A CRT can hold up to 30.000V or more depending on the size. The plastic wouldn't do much for you. It only offers a resistance to electrical flow, with enough voltage, there's electrical breakdown. Think of how air is most often an insulator, nevertheless we can see it conducting lightnings every now and then. When one is attaching the screwdriver to the TV set, if the screwdriver isn't attached to an earth point beforehand, the earth drain will be one's own body.

If you pause around 3:40, the package for the rubber gloves says Type I (no resistance to ozone), class 00 (500VAC to 2,500VAC & 10,000VDC), length 11" (from tip of middle finger to wrist or below elbow), size 10" (inches around palm of hand, front to back). Here's a link from Grainger: www.grainger.com/know-how/safety/ppe-in-the-workplace/hand-protection/kh-electrical-gloves-5-things-to-know From what I've read online, CRTs can have up to 25,000-30,000V while running. Higher class numbered gloves can protect you from higher voltages & are thicker, but they are more expensive & stiff to move the fingers. It sounds necessary to have a leather glove protector over the thin rubber gloves.

[@BrandonArnold0]

If you really want PPE for this task (which I do, but many do not), I don't think the rubber gloves shown are adequate. The voltage rating needs to be 30kV or so, which would be class 3 or 4 rated rubber insulating gloves. They are very thick and unwieldy, like space gloves or something, so I can see why many think it is just not practical. At the very least, something to where on one hand while discharging the monitor and not much more. These are several hundred dollars everywhere I have seen, and you need to send them to have them balloon tested every so often. If there is a tiny hole in the hand / finger then it will completely invalidate the glove (the arc always finds a shortest path to ground), which is why you need the leather over the top to protect the rubber. If you try to buy them for cheap on Ebay then you probably need to send them in to be tested, too, which cancels out those cost savings basically.

[@BenM39435]

[@mydecembermydecember]

I've read that CRTs can hold roughly 27,000 volts when operational. Short of buying Class 3 or 4 gloves which cost hundreds of dollars, do the lower voltage Class 0 and 00 gloves like you use (500-1000v) really even protect you? I need to do some convergence, yoke and flyback adjustments to my set and I just want to stay safe but wonder if Class 0 will achieve that.

[@n646n]

Just be a bit careful while doing it. You shouldn't be touching anything potentially lethal for convergence strips and flyback adjustments, but I'd be pretty careful around the yoke. Gloves are bad because they limit your ability to feel what you're doing, or so I've heard, and they won't really protect you at all if it's on.

[@mydecembermydecember]

i have a sony wega 24" and the text seems shakey and has some lighting jitteryness what could this be from?

[@谢筱清]

SONY-PVM-9040/2 96年日产放了很长时间原是好的.最近开机指示灯亮,40V电源正常无光有声,实測12V,15V,24V120V电压均正常行输出菅也換新,C2555 C脚只有46V低,因此显示屏不亮,请问下一步还可查哪儿?能找到图吗?

[@scralings]

I have the gloves! Hehe thanks for being so thorough. Also have you considered setting up a patreon?

[@RetroTechUSA]

Thanks. I will be setting up a Patreon very soon. It's coming around the time of my convention, so only 2 weeks away. I'll have some big announcements about that coming.

[@happysawfish]

Any magnets worth salvaging in this type of TV unit?

[@deepakkandari1109]

Why their should heigh potential at cathode tube terminal

[@TheNintendad64]

Can this adjustment be used to move the screen higher or lower? My screen is level but the bottom of the picture is cut off because the screen is too low. Can’t find much on a fix. Thanks!

[@jonniefast]

id check your service menu first bud you can likely adjust it with your remote

[@daveyofave]

What would be causing a single horizontal line to be displayed in the middle of the screen along with the picture?

[@n646n]

Bad caps.

[@paso2136]

Do you have some procedure to check x-ray emissions?

[@EvertvanIngen]

14:04 What kind of 'equipment' are you talking about?

[@GoldSrc_]

Anything that can output color bars, solid RGB color screens, dots, both vertical and horizontal lines, a few crosshatch patterns, etc. Just look up "CRT test patterns" and you will get what you need.

[@finite934]

got a 20 yr old tv off ebay that's got a rapid flickering problem, but image is clear otherwise. As soon as I bring up the OSD the menu looks a lot more stable. Can anyone guess what the problem might be?

[@smashingrandomthingzandrev2134]

There is this crt tv I can use but I'm not going to b able to open it. If there is dust there can it really heat up and damage the components

[@Rickenbacker451]

Got me a new and never used little 14" CRT TV made around 2006 to use for retro gaming. There was one problem though, after about 5 minutes it shut off by itself and after I turned it on again one of the AV inputs was not available and the menu was on a foreign language plus it was only 2 languages instead of like all european. That was super weird but after I unplugged it for a while it was fine again, tested it for some hours, ran ok with no problems. Somebody know what that could have been?

[@dewlivewireftw]

I have no idea. Maybe owner just fucked with it. Or, the TV was having a moment.

[@nogatco1]

Need help fixing my crt stuck on blue screen.

[@NeverAgain.BeNiceToPeople.]

Are cathode ray TV's magnetic? I wanna know if it's safe to set my laptop on top of one

[@n646n]

Magnets won't hurt your laptop bud. As long as it has an SSD.
