Good for you for sticking with CRT instead of picture tube. I'd like to see you channel on Rumble or some other platform.

It's effort to publish in more places. I have a libry/odysee channel that mirrors this. Maybe if I get more time I'll focus on exporting to more platforms.

Get one of those small air compressors, and I would not brush that fine dust inside. It does have a nice picture, I always liked those CRTs because you can actually see the phosphor stripes, even though it doesn't help with contrast in a well lit room.

Yeah definitely brush the thing outside, I use a brush and a small electric air blower, better than compressed air, no chance of liquid. Don't want to be breathing that stuff in, and don't want of in your workshop surely 😨 great video, love your work :)

The rubber wedges holding the scan coils often reacts with the copper insulation and can destroy the scan coils. I often slip a piece of insulation tape on the wedges.

I had for the longest time a Zenith 13" color TV from 1988 (the year I was born) and it had a great picture clear up until I got rid of it before the DTV Transition in 2009.

You might think based on the dust on the high voltage line that it would be high hour and the tube might be weak but it runs very nicely.

@dougbrowning82
@dougbrowning82 2 года назад
The only problem with VIR is that it relied on the producer to insert the reference signal (line 19) into the program. I'm not sure anybody has used it since the 1990s. RCA won an Emmy for VIR in the 1970s, and it was the basis of its Color Trak series of TVs.

That's a really nice set and the picture looks smashing now you have set it up. The crt is not as bad as i expected :-D is the switch on degauss coil around the crt working at all?, faulty posistor maybe? I was watching XrayTonyB and he was worried about the effect of that pot cleaner on old tracks. He is a nice bloke.
@JordanPier

It is working. I just think the crt was heavily magnetized. A few more passes with the degaussing coil cleared it up

i used to have 3 early 70s hitachis, and apart from the tubes being bit low emission, they all worked perfectly, unfortunately they had that instant on feature which kept the tube heaters running at lower current when set was 'partially off', probably why they were poor! i then got hold of an 80s? i think set in the mid 90s which had an unusual directly heated tube, with fast picture appearance, that was used for a few years until emission dropped too far

Interesting that the CRT # is in inches 19--- . Most Asian sets were millimeters . Good sets I had a 13 inches from 1987 for about 12 years. I didn't have time to fix it when it popped, and it didn't have a remote, so I got rid of it. But I still liked it.

cathode ray (electron) tube, is technically what it is, how it works, picture tube is describing what it produces, both are correct, you could in theory also call audio amplifier valves/tubes 'cathode ray' as again thats what they are, but not 'picture tube', unless its a phosphor tuning indicator,

But Why??? Sure you have all the tools to get it adjusted, aligned, and such. But to what end? Since 2009, you won't be able to use for a TV. It has no other inputs. So why put all that energy, and time, if it's still worthless? Time to retire your old TV tech, move on to something worth while.

I service vintage audio for a living. That keeps me busy with a two month backlog. The TV's are a hobby. They can absolutely still be used. I feed mine with an HDMI to rf converter, or HDMI to composite depending on if the set in question has composite input or not. I'm not looking for a stellar picture. It just needs to work. I don't believe in tossing things out because of age or obsolescence. Use it till it can't be fixed anymore.

@@JordanPier I belive in tossing them out, complete waste of time, money, and effort. Who in their right mind would ever want to play ANY games on a power hungry old picture tube. You can make up whatever insane excuses you want, but you are wrong. 'Backlog' for who exactly, you? You can't tell me you have actual customers wanting to buy that crap. There are very inexpensive lcd panels that can handle any game, without drawing 100 watts of power. No, you are insane to keep doig it.

Oh Really now, i have A 30 Year old RCA that lasted Without ever being Apart till the Recent big Ball drop, then Picture Tube Went out, Chassis is still Good, No filament on the Tube, Yet it ran every Day and Night For 30 years before Quitting, yet Its just the Tube went shot, the chassis still Plays, Has sound and High voltage, right now its just sitting, as too heavy for me to Move it, i now do Have a Projection TV i put another Lamp into, but i bet thats not gonna run as Long as the RCA CRT did. Why lets just see Any new Flatscreen run that long every Day and Night. Bet it won't For long. CRT's were Built To last, only Reason they can't be Used now, that stupid digital of which isn't any better than analog, As digital is All or Nothing, analog Didn't Care, even weak signals one still could watch TV. thats why i say, Things never will be same as they Used to be.
