When is a CRT not worth saving?

- I often get asked the question: Is my consumer CRT worth saving? The truth is you need to always take a few things into account to make the best decision. The condition of the Consumer CRT you are starting your repair with should be most heavily considered. Ask yourself these questions: Is this CRT a good model when working properly? Am I better off finding a working Consumer CRT that I can future-proof? Is my CRT even fixable? I go over my opinion on the matter in this video
Thanks for watching!

CRTs are like Vintage Cars. Some people love them to bits and restore them sometimes giving them a new Engine.
I don't like seeing Consumer CRTs go to waste, they are just as important as PVMs. I currently have 4. They all have issues though.
Not true they are not as important
@@ComputerTechnic217 they are very much just as important
@@mentalkidgaming357 no consumer crts are definitely not as important as PVMs
@@ComputerTechnic217 for retro gaming, consumer CRT>PVM because PVM's make the games look too pixelated compared to the CRT
@@ComputerTechnic217 Pvms are a very specific breed of crt. But there are so many other unique and interesting consumer crts that were on the market that have different quirks and interesting options. Consumer Crts are also capable of being modded for RGB if that is all you care about. But crts in general are dying out cause no one is producing them anymore it is just as important to keep consumer crts around as much as pvms for that reason alone. I would hate to live in a world where the only option for a crt monitor was buying a 20 inch or smaller pvm for $1300 or more.
Today's trash is tomorrow's treasure. There's going to be a point where ANY crt will hold more value than it does today, the question is WHEN. If you offered me an RGB modded Consumer trinitron for $500 that might have sounded insane 10 years ago, but now that thing would be gone in a week.
It's pretty hard for me to let any CRT go that isn't working good. I have a huge graveyard in my shop of stuff I hope to get fixed in my lifetime. The issue is when someone who doesn't regularly work on CRTs wants to repair or restore one. They would be better off starting with a good working CRT and do the preventative maintenance rather than picking a non-working CRT to try and fix most of the time.
kenny lauderdale rgb modded? Lmao. When you live in Europe....
no one will buy that for 500.
Pabloxd123 maybe in 2100 when crts will extinct.
@@mtunayucer yeah
I got a Toshiba *20AF too, for some reason the red gun was boosted way more than the others when I got it and every red dot has burn in on it while the green and blue ones don't, I already turned down the RCUT value and it looks normal but the damage has already been done, just glad it is consistent all over the screen!
bruh ew
I think you underestimate the C.R.T. fandom not wanting a C.R.T. because it only has R.F. in.
IF it has style, there is always someone out there creating a rec- room with retro flourishes, that will be willing to buy it, for the right price.
I have a Sylvania from 1987 I use but it has a small scratch on the screen. Right now I'm using it as a bedroom tv but eventually I want to find a way to fix it or replace the screen. Anyways main point of this comment is I agree
It's really a shame that burn in is almost impossible to fix imagine how many CRT's would be useful today! And if that was possible we could probably chnage damaged trinitron and replace a new one and lots of old school TV's/pc monitors would work and we would also help with electronic trash.
It really is a shame. Tubes are the Achilles Heal for the CRT display.
@@RetroTechUSA For repair? Yes. But if they did not have screens (tubes) that regenerate their image at the speed of light, we would not want them. For example, I do not think plasma displays will have the same resurgence as C.R.T.s, for gaming, because the imaging processing circuit boards of the time, cause a substantial amount of lag. ...they are good for Blu-Ray content, though.
here in n.ireland they smash the tubes up in the local recycling center they wont let you take them..i tried even asking to buy ones but no if its in the recycle center its getting smashed...
@@fatbelly2438 That's dumb of them. ...maybe if you lie to them, and tell them you want to smash it at home for your own amusement, will they let you have one, or several.
This is a nice episode as I'm actually considering repairing my bang and oflusen beovision 1 crt. I got it from a guy and it powers up nicely. However after about an hour or so of gaming, it started popping and smoking from the rear!! Some serious burning smell but screen is still playing properly...
Makes me wonder if I should try a full replacements on the psu but I'm no technician. Not even sure where the problem is... And parts could be really hard to find...
Having kinda mixed feelings to let this nice crt go to waste if I were to junk it... 😣
Don't use it if your actually smelling burning. It's a matter of time it blows up. Burning silicon is also quite toxic. Open the back, look for the problem.
I'd still recommend opening yours up and doing a visual inspection. You should be able to see what's causing the smoke and smell. It could be a bad cap has leaked or simply dust has built up on the hot Components and is starting to cook when you turn the CRT on. It is common for these older CRTs to have lots of dust built up in them.
@@RetroTechUSA I've actually did some cleaning immediately after I bought the tv from the guy. Definitely not burning dust as there's loud popping sound...
I'll probably open it up again and try dismantling the power supply board to take a closer look again, and at the same time check for any burnt caps on other boards.
Guess i'll try one last effort to save it before it goes to the junkyard...
@@viscountalpha I've already stopped using it for a few weeks.. Fearing of it eventually catching fire. The house does stink with the burning smell even a few days after it started popping...not gonna let that happen again 😅
@@keithchua5840 Power it up with nothing flammable next to it, and use a power strip with a replaceable fuse built into it. Violá! No worries. ...just don't breathe the smoke in.
i mean i got a really retro tv that my grandma used to use in the uk in around the 50s, and hasn't been used in over 40 years. the crt is as big as a door and has its own cabinets installed into it. spiders live inside it and everything, i doubt it even works though.
When the rings tube?
How to adjust the rgb?
I do have a slight disagreement. After component/jp21/scart/s-video video inputs, I think a consumer C.R.T.'s value comes from its style. For instance, I hope to hook up a 1983 13C302 Magnavox C.R.T., that I saved from being trashed, to my NES and Sega Genesis, because it fits the gaming time period (It also does not hurt that retro video game consoles made pre-1994, had a separate R.F. out, so you can hook them up via R.F. and their mulit-out simultaneously, for multi-screen, or capture card, applications.). I also saved a Broksonic CTGV-2736, and coincidentally, its style and size fits the Gamecube/PS2 era, nicely.
badreality2 or you could just use a 20L5 for everything NES-GameCube
@@ripetika1600 Yeah, I use a Sony PVM 1340, and a Sony PVM 8042Q, but I played the Sega Genesis on R.F., in the 1990's, and its dithering is amazing in R.F., on a C.R.T., and hooking a NES up to a "wooden" tv, just fits its era so perfectly. What I plan on doing, is hooking up my Sega Genesis and NES, dually, with their R.F. connections leading to the Magnavox, and their RGBs leading to on of my PVMs. I will play games on the screen that suits my mood, and it will be a dual screen setup, for multiplayer games. I am almost too grown up, to huddle next to a tv, for local multiplayer.
I want to hook up my 3-Dimensional games to a larger C.R.T. television screen. I have heard that 3-Dimensional games are more immersive, on a larger screen.
C M Yes, I am young. No, I have never had a CRT, so no I don’t have the same nostalgia as you and this other person do. I respect that you are trying to experience it the same way you did when you were younger. I never had to use RF, I’ve just used composite for everything, but now I want to try to view the image in the best way possible and that happens to be on a RGB monitor with 800+ lines on a modded console. Like I said earlier, I respect you, thank you for enlightening me to your way of thinking.
Blinking black screen
I have a Sony KV-32S45 Trinitron CRT TV from July 1998.
I use it to watch TV through a HDTV converter and play NES games.
it works but has a couple problem.
Turn on
Audio comes on after 7 sec
Stand By/Timer light blinks 200 times
Video comes on
Screen blinks black and good picture every 18 seconds
randomly based on what kind of video brightness picture there is.
I think dark scenes blink more.
Bright white scenes don’t blink at all.
But not always.
NES Dr. Mario works with no blinking after tv warms up.
Do you have any videos to fix a screen that blinks black and returns to normal randomly?
I can’t seem to find any videos because when I search for CRT blinking it comes up with problems related to the red LED Stand By/Timer blinking and not the screen.
Thanks
John
This is so weird to me... I never knew CRT even had burn-in risk. We used to do all the wrong things with those TV's and monitor's (static logo's, gaming HUDS etc) but I guess we got lucky? I was researching OLED burn-in risk when I learned that CRT has it too, but Ive never run into it.
It's a different kind of burn in, it's not inherent like it is with OLED. If you take good care of your CRT and don't leave it on one thing for hours and hours then in theory it would hold up much better than an OLED after ten years of use.
@@awesomeferret Yes, it takes A LOT of hours for a CRT to develop burn in of some static image part. We are talking about many thousands of hours here.
On my CRT computer monitor I can only see a very light burn in of some elements that never move (such as the taskbar) when there is a full screen of just one color, say white (otherwise it is invisible).
My monitor has had >20,000 hours in 12.5 years at this point and the mentioned desktop elements are there for probably at least 70% of the time I use it. So there is not a lot to be worried about in my opinion.
However if there is burn visible on the phosphors when the screen is turned off it surely is severe. Monitors with severe burn in were often switched on 24/7 for a decade and more displaying some static part.
@@martinweizenacker7129 One of the most famous examples of severe burn-in on a CRT online is an old CRT display that was used at a DMV office that had the text "Please wait" so severely burned into the screen that you could actually see the text etched into the shadow mask of the picture tube.
Oh-No!! I hate it when a unit isn't savable Steve. Well, at least it can be use for parts to help another unit out. 8^)
Anthony..
Yeah, Screen burn is just plain awful! At least the rest of the CRT can be reused.
Or that you acquired an Rare (NO POWER) 20" CRT for 25 bucks... It's very much fun to repair it and see her light up for the very first time...
i just got one shown on ebay as working 14'' received and nothing works just a squeal but no indicator light and no picture the screen however has that feeling of static but it don't blink on
1st logo dell color graphic display rebranded Mitsubishi-XC-1429C that i got mainly because i wanted it to match my dell 333d professional computer (that is where the term pc came from) i thought it might increase the value if it had a matching monitor
but the darn monitor don't work i narrowed the issues to either 3 different things
1. blown fuse 2.leaked caps 3.damaged fly back transformer
it is a electrical fault issue but i am afraid to accidentally break it or break myself i am untrained in the art of crt repair and i fear the might of the explosive lead filled lightning tubes.
Crt tv are worth to save and reliable too
where do you get the pvms from
Hella late but you just have to get lucky. Some people don’t know what they have. Gotta check out garage and estate sales.
Good video man. Hey I have a Crt problem and didnt see a video addressing it. Can I send you an email with my question? Do you have a email?
Sure, snutt541@gmail.com
Keep the dead tubes
They canbe refurbished and enough of them make it worthwhile
