I had picked up a 62'' and a 52'' big screen TV the other day... Wasn't much except for the projection stop light looking thing.
But man I was in for a surprise.. There's some kind of oil or KY jelly liquid inside those lenses, had to mop it up with 2 towels off my floor when i unscrewed the wrong thing lol.
Thank god for no carpet though.
YEAHHHHH. I've broken down around 30 of these so far, have about 40 still in storage. They're fun. 3 BIG aluminum heat sinks. I believe that oil is "optical oil". I swear that stuff does NOT evaporate. EVER.
Glad I read that before I hacked up the one on my back porch and created an oil slick. I've found a bunch of those lately, seems like anyone who has one is looking for a place to dump it.
According to my electronics shop man, the liquid in between the "crt gun" (glass tube) and the colored lense is actually anti-freeze. It is a clear anti-freeze,
which makes sense because I bet those babys get hot!
And don't forget that the housing that is between the lense and the "tube" is cast aluminum, that is of course in the rear projection 3 tube set-up.
a youtube video i watched said it was mineral oil
Probably is mineral oil to absorb heat away from the components.i watched said it was mineral oil
I think that video said something about using mineral oil in biodiesel. Or maybe I heard it from somewhere else. I just tried looking it up and couldn't really find a conclusion on it but if it's true than the stuff might be worth some money to the green folk.
I've messed around with a lot a car motors in my life, and the liquid in those housings sure feel like anti-freeze, it leaves that tacky
feeling like glycol on your hands.....maybe different manufacturers use different stuff?? I've scrapped a lot of sonys......
Boy I wish I had looked at this thread before I tore apart my TV, I was stripping it in my dining room because I didn't want to carry it outside by myself (those things are heavy). I unscrewed the tube from the aluminum and splash, all over me, my kitchen table, and the floor. What a mess. All the wife could do is laugh at me as I was cleaning up the mess. Oh well, now the other 2 will be taken apart in the garage after I drain the oil out of them. LOL
Same with the oil spilling out.....
Actually was a bit dismayed with the whole setup, not much metal to scrap out of it considering the 3 CRT guns.
Just some mirrors, lens/plastic sheet & 3 cool glass lenses & small copper amount, Ali heatsinks & 1 cool toroid tranny for keeps.
I had a big tv just like that, it only had three things of copper that i took out, so i put it at the road.The next day i saw some junkers outside going through it and they were out there for about an hour, so i finally went out there to ask them what they were doing and apparently they were taking off somthing called condensers. He said you can get about 2 bucks a piece? Iv never heard of this has anyone else?
I usualy get the three copper yokes, and or the 3 glass stop light assembly sold as 'weight'. Also the circuit board and cut out the wires and thow them in the wire bucket
the optically clear glass on the front of CRTs is quite valuable and a company or two in cali will take them from you. They found a way to remove the lead from the glass so there should be value on the west coast as seen in this link below...too bad i'm in philly
