I can connect my Blu-ray player to my TV from 1968.

That is very cool.  What signal and cables do TVs of that era use?

I see, very cool.  I wonder if a blu-ray and a dvd look the same on such an old TV with limitations. 

Have you ever been shocked by an open CRT?

I'm reminded that collecting doesn't have to make any sense  Smiley

They don't, the picture is less sharp on an old TV.

No, I'm not that stupid.  Grin
But that risk does make repairing old TV's more exciting...  Cheesy

I figured it wouldn't make any difference on older sets.

Hehehe, according to my CompTIA A+ Certification studies, CRTs can pack a lethal charge in the capacitors even when unplugged!  I personally have never heard of anyone dying at the hands of a display though.  That is almost embarrassing.  Imagine someone being killed by a VideoPac G7200!

 :)I started out collecting only atari 2600 items until the internet showed me all the systems i missed out when i was a kid. using a emulator is not the same as having the console to play the games the way it was meant to be played. I have bought a atari 2600,intellivision II, colecovision with all expansions, odyssey^2, nes, snes, nes64, and ps1.  To me having only one game console is missing out the enjoyment of playing all the games. lets face it one game title is not the same on differn't console's and its like playing the game for the first time all over again. to me space doesn't concern me even though my living room looks like a arcade at the mall it just makes me happy. if collecting one system makes u happy then you are happy. if it doesnt expand ur self to other systems. if i could make a suggestion i would start with the colecovision. as my opinion goes its the best vintage system out there and i think the nes was a huge expansion of the system.

Um.... I actually had the unfortunate chance to see a guy get zapped by a CRT. The guy was out for hours. Supposedly, it almost killed him. Can be rather dangerous - and the scary thing is, I work around them. Of course, I take precautions!

Always keep one hand in your pocket when you can. It's the jolt accross the chest that will kill you.

Not only capacitors can hold their charge, the tube itself will too. The conductors on the inside and backside of the tube with the glass (isolator) between them act as a capacitor. Picture tubes of color TV's work with 25kV.....

Capacitors in switching power supplies can hold their charge too, so even fixing a G7400 can be dangerous. (But I'm not sure if it would be lethal, never tried.  Grin )

Sounds scary.  I wonder if LCD screen carries a change like that.  (I assume it is much less than a CRT.)  Lets hope the Odyssey 2/Videopacs are never responsible for killing any people. lol  I suppose it would get their name out there a little more though Wink

Nah! The worst would be a loud snap if you shorted them. The voltage is so low
that you would not even feel it. I dont think there is enough current in such a
supply to deliver a lethal shock.

I'm talking about the capacitor which is directly behind the mains rectifier. When the console is on, the voltage across that capacitor is 310 Volt. It is definitely not completely discharged after the console has been turned off, and will hold a voltage way above 100 Volt.

Yeah that one might hurt then. Smiley I did not know the G7400 had it's supply built in.
