A 1968 Sony Trinitron KV-7010UA! :ntwrthy:

You guys probably hate me now! Lol
I cant believe it, it was a garage TV used by an old mehanic. It's a little beat up. Missing the handle and bent up corners on the thin sheetmetal.

But, it works!

This is the one that says "TRINITRON COLOR" on the top and not "MICRO COLOR" and the UA must me late production.

The story is my buddy's friend lost his house and was selling everything off. Way out in the sticks of Placerville, this puppy was dirty. In the garage where all this stuff was being sold off were engine parts, flathead Ford complete engines, and VW parts, a 1966 Chevy Nova with a 383 stroker conversion, a 1982 Toyota 4x4 lifted, and some odd and end starters, heads and 55 Merc parts. Looks like he was planning to chop a top on the 55 Mercury sitting in the other garage.

Up in the rafters in that garage was this sony my bud Roger told me about. Dean was the one selling off everything. Roger said, hey come out here, I know you like TV's. So I did, and long and behold I opened the barn door and walked to the back of the garage and.... The first USA Trinitron..

There was also some really beat up Zenith stereo and a mid 80's 13" trinitron that he said that one's for sale for 200 as well. He can keep that one, dime a dozen.

So now Im wondering.. After seeing posts about how rare this set is I must ask... Is this set worth $150 bucks? I cant get Dean to budge.. I talked him down from 200.
What do you guys think?

I have a popular science article on I think that set already loaded on my ftp site. ill post it tomorrow.
if its rare and something you want go for it. it is on the high side but don't set yourself up to regret not doing it

Yeah, when KX250rider and Jhalphen see this, there going to hate me, Lol. I think I read the article, but post it anyway. Thanks Ctc17!

Just sucks about the handle and the sheetmetal. The antenna is perfect although.. Kinda makes you think in a mechanic garage environment, the first thing to get broken would have been the antenna.. There sure is alot of greasy residue all over the VHF knob and power/volume knob..

Pics asap please!!!! I'm envious, but very happy you got it! Does it have all the aluminum trim? Mine was missing most of it, as it had come loose evidently and got bent and busted off. Missing all the knobs too, and was all beat up (lying outdoors in the desert for a few years). If yours has the trim, and the knobs (unique to that TV), I'd say try to restore. I know a place that will restore damaged or scratched aluminum trim, and the leatherette can be replaced if it's bad.

Charles

PS: Please put me in line, in case it ever comes for sale :music:

Ok here is a pic. It's still in the garage. I should be able to get it tomorrow or Sunday.

That's what you call a survivor, I guess. Congratulations!

If this is to small let me know and ill try and find it and rescan bigger.

Hi FreakAfter8,

Mind the handle, it will NOT support the set's weight by itself, always support from underneath. Euro KV-1220 & 1310 had the same problem.

IMHO, US $150.00 is cheap for this rare model.

BTW, some screen shots of mine...

Very nice set you have and the raster looks good! I hope that the CRT in this set is ok. I have yet been able to pick it up from the gentleman selling it, as I have not seen it powered up in person.

Thanks for the pictures.
BTW, I was not aware that the european KV-1300 series had a carry handle. I know that my KV-1220U has 2 plastic handles encased in the wooden structure. I have to go look at my KV-1200. I dont recall a carry handle on that set either. Very interesting.

Thanks,
Shawn

The dangerous handles are the fixed ones with cross piece attached to chrome brackets by a little screw at each end. Screws come out, and the cross piece will flex away from the brackets and fall out! That's true on the KV-5000/5100, and evidently on the KV-7010. The others with swing-away handles like your KV-1200 and the KV-9000, don't have that problem.

Charles

nice playing little sets.saqw few here but they were very sharp and geat looking colors.back when sony made something special!

Hi to all,

to confirm my remark about the absurd use of carrying handles on 50lb+ TVs, here are two pictures of the French KV-1220 DF which came to market in 1972.
It's a 819/625 set, VHF/UHF and SECAM-only color decoding.

They keep on going forever and any French TV collector worth his salt has one. My friends at the Paris flea market who often have one of them in stock, listen to hear the dreaded "craaak" when the silly buyer pays no attention to their warning "Do NOT carry it by the handle alone". The noise is usually the handle ripping out of the plywood and the CRT survives; amazing!

I hjave read alot about that KV-1220DF. That is 1972 and I assume at that stage the 3AT2 was eliminated? Or does it still use it? THe cabinet is very close to my KV-1220U I have.

Hi Shawn,

The KV-1220DF had the EHT vacuum tube rectifier. I don't think they ever went solid-state on this model.

Next model in line, the KV-1340DF was all solid-state, and close behind the KV-1812DF.

Much later, in the early 90s Sony market tested this KV-16WT1B, a small-screen 16:9 set PAL/SECAM. I don't think this model was ever produced for the US market. Note the strange triangular pointed rear of the chassis.

Wow! I have never seen an early 16:9 Trinitron! And that CRT looks great as well. That is way cool! Now did that set have 405 line scan? I'm not too sure if France adapted the European system or not..

Hello again,

No 405, never in France. Also totally abandoned in the UK from the early 80s.

The 16:9 Sony set was a single standard 625/50 TV

Best Regards

jhalphen

That is very cool. I hope you find a handle or recreate one fron scratch to match original.

Hey Shawn,

It's a little off topic, but does you pal still have any of those ford flatheads? any idea of price?

Just got the television today!! I'll take pics this weekend and post. The flathead ford heads to my knowladge were saved and sitting in a friends machine shop. Not sure if he wants to sell off anything yet, sure i'll find out soon. Suprisingly the bank had all the stuff in the garage sent out to the curb for pickup. it was pretty much free market there!

Sorry I didn't post back sooner, I didn't see your post til I scrounged up the thread again.


Shawn

Hey guys,
sorry I didn't show it off earlier.. Here's some pics of the 7010.
The first pics are from the set with the bezel off to clean the face of the CRT and glass. I decided to take pics so you guys can see the face of the primative trinitron CRT without the bezel hiding the glass envolope. The pics are a little fuzzy, I took those on my iphone.

Here is a closeup of the CRT in action. Nice bright CRT.
I still have the cover off trying to straighten out the sheet metal.

All I can say, is WOW; so glad you were able to get hold of that set after the concern of losing out on it. Congratulations, Shawn!!!

Can a weak horizontal driver transistor cause a sync lock issue and stretched horiz width?

Can a weak horizontal driver transistor cause a sync lock issue and stretched horiz width?

In theory, there's no "weak" transistor... I'd say more likely a cap in the horziontal oscillator or sync circuit. I suppose a silicon transistor could leak, but it's unlikely, and if the driver were acting up it would most likely blow the output.

Maybe check these electrolytics: C510,512,514,517,518, and 519. Those are located on the SD board near Q504-Q505. ***These location numbers are per Sony; Sams sometimes uses it's own location numbers on early Japanese schematics.

Do you have the Sony factory book on it?

Charles

Thanks for the help, as always Charles,
Lol, no I dont have a book. Did they use paper back then? lol
I did some "poking around on the horiz deflection board. There are some caps in question. Also on this set the big filter cap has a board connected to it. This sits above the CRT. There is a resistor burned. I should check the ESR on this puppy too as it seems there is a little bit of a hum cycle in the raster.

I'd say that could be the cause of the hum, so I'd check that can. However, the ESR meter might not see the leak on a large, higher voltage cap like that one might sound like it is. Best bet is to scope it and see if there's any unwanted AC pulse showing on the cap. And of course if it gets warm, or is oozing at the terminals. I have the factory manual on it, so if you like I can send it as the others. The schematic is a fold-out single page at appx 24" x 36". I might try doing a photo and eMailing it if you are OK with big files. We upgraded our cell modems, and it seems a little better now for big files.

Charles

That would be sweet if you could email it to me. Im almost certain I have found a few out of spec caps so far. I will probably tinker with it after the holiday.

PM sent
Thanks

Here are some more pics of the chassis. I stoill cannot locate a CRT model number yet.
Im in the process of replacing lytics on the H osc

Hi Shawn,

If you give me your Mail address, i can send you the KV-7010U schematics.

I have a pretty complete scan of the service Manual.

To Charles: does your Sony manual include sketches of board location & physical disassembly and a parts list? i am lacking this data.
