My Sony Indextron is off to Andy right now...
 
It shipped out today for repairs. Andy is going to post pictures and comments here. Any questions, let him know. I'm sure he knows a lot more about Indextron than me. :thmbsp:

waltchan 06-12-2007 07:53 PM

Andy, how's my Indextron doing? Any pictures?

Wonder why Sony used El-Cheapo caps in something that was sposed to be a Technology Showpiece, like this thing was ? If they HAD used decent parts, Indextrons might have been the Next Big Thing, instead of a footnote... Seems like they were setting this thing up to fail..I can't believe a supposedly business-savvy outfit like Sony would purposely spend megabux to bring something like this to market, only to have it crash 'n' burn so spectacurally, but that sure looks like what happened..Looks like some developmental engineer would have said to his boss, "Uhh, Houston, we have a problem.." or whatever the Japanese version of that is...

The orange plastic is what collects the light from the index stripes. It's the same plastic that's used in store displays to give them a neon effect. It collects light from the surfaces and concentrates it along the edges.

Hmmm... could it be fluorescent so it picks up ultraviolet from the index stripes and converts it to orange for pickup by the sensor? Do you know what the index stripes consist of?

"Sony color TV from the 80's or 90's" and "Replace lots of electrolytics" go together like "Pizza" and "Beer". :)

I thought the seller said the TV "WORKED"???? $700 and it has leaky caps that badly? I wouldn't buy a used car from that seller... He might say it "RUNS FINE", even though it has no oil pressure and a few rod bearings are clattering.

Very nice fine, Andy, and thanks for saving this Indextron. What about the color and the pincushion issues?

Richard D 06-18-2007 07:01 PM

Hey Sandy Do you mean a company like...
 
"business-savvy outfit like Sony would purposely spend megabux to bring something like this to market, only to have it crash 'n' burn so spectacurally"

To me it seems like that's the way GM does business, rush something to market before it's ready, piss off everyone who buys one, then when you get it right pull it from the market. Such as, Pontiac Fiero, Cadillac Allente, Chevy Vega, Buick Reatta, 1996 Impala SS, Oldsmobile Aurora, Oldsmobile diesel(just kidding, it was always junk) and more I can't think of or spell correctly.

I have heard that, with this sort of color CRT, that you can never go to full black in parts of the video image, or else the index color control switching circuit looses track of where the electron beam is and may make a mistake of which color the electron beam is aimed at, at the point in the sweep when the image starts getting bright again. So you have to make black areas of the video image at most a dark grey. So it will look a bit washed out.

Hey, hey... I like that 350 Diesel! They're actually pretty reliable, as long as you replace the head bolts with the upgraded ones... But you're right about rushing it to market. They should have done more testing and upgraded those bolts before it went to production!

Evidence on that engine being desireable is that nowadays, they go for about 3x what the same car with the gas motor goes for on eBay. A '79 Seville just went for $13000 this year with that 350 Diesel in it.

Richard D 06-19-2007 10:29 AM

So many large companys do this, Sony, Sanyo, Panasonic. For the cost difference of hardend head bolts over the grade normally used GM bean counters caused the entire engine line to be remembered as a disaster instead of the leap in technology it should have been, small block V8 Diesel while the imports had shaky, underpowered inline fours. When done correctly though the results can be good. How long did the GE Porta-Color line remain in production? Did they have the best picture quality, no. But for the most part they worked a long time and were cheap to manfacture and buy.

Even after adjusting the beam landing and focus, the purity is far from perfect. It's not noticeable on normal program material though. It's better than it was (this was contributing to the green tint). The actual picture looks better than in the pictures, but the black level isn't very good. In many way it looks a lot like an early LCD set.

I'm amazed it works as well as it does. It has to alternate between red, green, and blue as the beam passes over the phosphor stripes. That requires much higher bandwidth than a normal video output stage. The electron gun also has to be capable of much sharper focus than a normal small screen TV.

Looks good. Overall, would you recommend this Indextron to someone, or is it not worth the high price since the picture quality isn't so great?

Keefla 06-20-2007 08:00 PM

In my opinion, if i had the money to buy this set, knowing that i was buying a piece of TV history (maybe a dark spot for sony, but still innovative), and better yet to have it be WORKING...id definatly go for it. some may say its a lot of money, i say if you got it use it.


good score on the TV waltchan, and great job keeping it going Andy!

Sandy G 06-20-2007 09:18 PM

I've heard they're rare as hen's teeth, Sony supposedly withdrew them from sale, & tried to recall the few that had been sold. Ones that work-this is the only one I've ever heard of that actually works. These things may actually be even more rare than CT-100s...

kx250rider 06-21-2007 02:33 AM

They are VERY rare, and it's true that they were recalled. And ALSO YES, this is the only working one I've ever seen or heard of, except possibly for one in the hands of a TV collector in France.

The collector at France already said it no longer works.

are they all brought down by bad caps?

waltchan 06-28-2007 09:47 PM

Someone is offering me $2,000 for it...
 
You would not believe this, but I received an e-mail from a collector, and he is insterested in buying the Indextron from me for $2,000. Should I accept his offer? I do really like it. If you own it, would you let it go for $2,000. I'm stuck. :tears:

YamahaFreak 06-28-2007 10:57 PM

Sorry to bump an old thread, but can someone tell me what exactly an Indextron is? And maybe show some pictures.:yes:

ChrisW6ATV 06-28-2007 11:18 PM

Yamahafreak-

I asked the same question about a month ago and got some good amswers and links in this topic:

KEEP IT!!!! Keep it. Keep the indextron. The TV stays. Keep me(The TV was speaking).

Just remeber, the longer you keep it, the great its value increases in the long run. In two years that offer of 2000 might double, and then you'd be kicking yourself if you sold it now!

Best regards,

I have to agree. You have something very rare there, and it's even rarer because it works! Just think of how much time you'd need to spend to get another one. Someone will offer you 2 grand for something else. That Indextron is worth more than money.:yes::thmbsp:

Sandy G 06-29-2007 05:29 AM

I'd keep it, too, unless I was like starving or in dire straits. This is like The Wailing Wall to the Israelis, you DON'T just "give it up"...

Richard D 06-29-2007 08:46 AM

Sandy G and others are correct, plus
 
there is a small chance that it is an attempt to seperate you from the set with a worthless check, bank draft or money order. Plus you paid over $700.00 plus shipping and Andy's tune up. I would hang on to it unless your transmission falls out while driving home in rush hour.

I didn't think of that:yikes:

bgadow 06-29-2007 11:47 AM

My personal opinion: if somebody put in my hand $2000 in real greenbacks he could have the TV. That's a pretty good profit which could be plowed into other finds. However,that is just my opinion and I have never been a fan of Sony TV sets.

Richard D 06-29-2007 11:59 AM

Now that you put it that way, it is easy to tell someone else to turn down a $1,250.00 profit. If the deal is legit I probably would go for it.
Richard

Sandy G 06-29-2007 12:01 PM

I wouldn't be surprised if it's a real offer from a real collector. I can think of a couple of collectors here on the west coast who might make goofy-high offers like that because the have the money, if they might REALLY want the set.

But obviously, use good business sense and DO NOT, NO WAY, NO HOW, accept PayPal. The buyer can stop payment any time later on, and rip the money right back out of your bank or credit card if they tell PayPal that the item wasn't as said. Also, of you take a foreign cashiers check, a fake might not be discovered for 2 months! If it's a foreign buyer, have them send you cash in US dollars in a registered letter, or tell them that your bank takes 45 days to clear a foreign cashers check before you ship it.

Charles

waltchan 07-01-2007 02:29 AM

Thanks for helping me here. I decide not the sell the Indextron yet, even for $2,000.
