Good job, here's your next project.

Ponti ick!

[Reece]

Yeah, but look how nice the interior panel survived.

At KV-1926R: I 'admitted' that for the sake of comedy...

Most cars past the 70's are WORTHLESS JUNK IMHO(and that includes most new cars). What you show is likely 70's and probably not even good for parts anymore....

At Eric: Yeah, if it is free I'll take it! It will probably be like a big old version of the Sylvania...Hose the mud off, replace some parts, spray paint over the rust and ride off into the sunset...

Seriously where the heck have those cars been, how did they get that ruined, and why would someone do that to them!?!?

I like 50's era styled cars like that Chrysler. The bold futuristic look back then with the fins was really cool. My favorite era was the late 30's through around 49' when most makers switched to an ugly bland look(like they were trying to imitate those hideously plane Kaiser/Frazers) that stayed through to about the mid 50's.

I do appreciate the humor, but please don't drag this thread off topic for too long. Near the end of the Elvis discussion I was so sick of it I considered gathering and burning all the Elvis recordings I have....

Good work Tom! Nice to see the Sylvie display video again! Is there sound with the video now? I also like that you can save the back panel of the set, good idea! :-) :-) :-) Someday I'm sure we'll see COLOR on that set, too! Best wishes on the Zenith roundie vert. work, as well.

The Plymouth in Eric's post is the one which was sealed in a time capsule for 50 years. They tried to preserve it, coating it with cosmoline and wrapping it in plastic, but the vault turned out to be far from waterproof. According to the Wikipedia article, several attempts were made to restore it, but it's too far gone (well, maybe it can be done, but it'll probably be akin to "grandpa's hammer").

Hi Dave.
The sound is there, but there is some buzz with the video fine tuned in. It has had sound since before I got the horizontal section to function...Though before I worked on the video and AGC it would loose sound well below the highest AGC setting that produces video.

I've been working on my TVs less lately as there are radio meets I need to prepare stuff to sell at in order to have money to keep getting stuff I need for my projects, and to make space so I can accommodate new finds...I do get sick of radio work from time to time and switch to TVs to keep sane.

The Pontiac is from the 60s. I suppose what you said about cars made after the 70s was a thinly-veiled dig at my love for the Mercury Lynx.

As I recall, even YOU made a crack about Elvis' TV the last time it was posted here. Edit, after some investigating: You did! And in this thread no less! Go ahead and burn your Elvis records if you want, makes no difference to me.

I'm outta here. Taking my jokes, and my support, elsewhere.

Touchy, touchy KV-1926R!...
You are reading things in my post that were never written, implied, or thought. I was not offended, but I did not get much of an impression comedic tone from the quoting of the 'nut' comment so I was merely pointing out that I said it for humor lest you think I'm actually someone who thinks of himself as nuts(which I don't...Usually). There was never a 'dig at your love of the Lynx'. That statement about my taste in cars was if you actually meant to post a picture of a 5 year old ruined Ford(one of those I would not touch with a 10' pole). As far as taste in cars goes to each his own...I may not find anything redeeming in the styling or mechanics of a Lynx, but that is no reason for you not to. Even the Yugos of the car world should at least have an example or two preserved so future generations can see what tradeoffs were considered acceptable by a given maker at a given time, and it is folks with different tastes from average that keep cars like that existent for future generations that may come to love once odd ball cars or need to gain historical perspective from them.
The comment about the Elvis tangent was not addressed to you alone but to every one who commented on the Elvis TV and posted photos of stuff not related to Sylvania TVs. The burning records comment was a bit of a comical exaggeration of my dislike of the thread being driven off topic by that. I did comment on it twice(the second time had a 'veiled' attempt to imply I was getting tired of the off topic posts and it was direct and strongly implied when I later started a post with 'Back on topic'). To be fair I did not start the Elvis tangent which occupied nearly one third of the first two pages of posts and about two thirds of the second page as well. There was a thread on or derailed by the Elvis TV months before this topic, discussion of it here is redundant.
I have seen threads on here get SEVERELY topic hijacked, and want to prevent that in my topic here. I want to prevent that because if It gets too out of control I'll have to either abandon this topic and start a new one on the same thing, or ask the mods to edit out and or delete the hijack posts....Both of which would likely ruffle a few feathers, and be very rude. Do you have a problem with me trying to prevent things from getting to the point of having to stoop to that? I'm fine with and, given what I'm working on, expect some jokes, but when a tangential topic dominates a page or more of posts in my thread I have every right to ask that it not turn turn in to a hijack, and continue on under it's own separate topic, and that tangents in the future not go too far. Perhaps I went too far with the 'burning records' comment, and am now making an ass of my self over explaining it...
NO offense or insult was intended now or before. Sorry if it sounded that way...
What is the story on that Pontiac BTW?


Adam, that Plymouth story is really interesting thanks for the link. Too bad they did not do a better job of keeping the water out... Someday I'm going to have the money and or luck to have a vintage car of my own to work on.

PS: to the mods I don't feel any need to edit anything in this topic presently.

It's now a usable set again!



Last night I got the color osc. to properly synch fixing the last major lingering issue.
I still need to preform some gray-scale adjustments and other control tweaks but it is now producing a watchable color picture.

Repairs since last time consisted of replacing a single transistor in the color circuit to restore color video, tweaking the color osc. improperly thus making the feeble color synch and off color worse, replacing several parts in the vertical circuit to allow it to synch in the range of the hold control, and finally through dumb luck finding positions of the color osc. adjustments that allow solid color synch and proper tint range. I say dumb luck because the sam's adjustments I tried were not seeming to have the affect that they suggested, and I ended up just twiddling the two controls they had me adjust until it just popped back in to the proper setting...Perhaps my least favorite part of that procedure was that the osc. coil is located RIGHT next to the HV lead and the open terminals of the flyback and tripler thus leading to several unpleasant static(arc?) zaps before the idea of obtaining a rubber glove came to mind.



Here is a picture of what all was replaced.

The parts to the far right as well as the tube were replaced to restore the raster, the transistors and resistors on the square were needed to restore video, the parts by the tube were replaced to fix the vertical synch, and the lone transistor on the rubber grommet was replaced to regain color.

This was a pretty cheap restoration. All the resistors and some of the caps came from my NOS/used parts bins and the transistors were equivalent to 2N2222's which da shack sells a large assortment of for around 3$.

A good portion of the resistors in problematic circuits were off or near tolerance, and I suspect more of them remain, however unless performance issues necessitate further work I think I should leave well enough alone...I've damaged enough PCB traces already.

Now that I've proved to myself that I can fix virtually anything I think I'll go and revisit some old dog project sets I shelved years back.

Once it is all back together I think I might drag the Sylvania in it's as found cosmetic state as well as a power and a signal source out to the spot where I found it. Then take some pictures of it working in the place it was found....Maybe I should take it to a flat panel dump and take some pictures of it working surrounded by trashed flat panels as a statement about our throwaway society and the comparative quality of vintage American products to the imports of today.

[bgadow]

Excellent work! I knew if you stuck to it this would be the result. Those Sylvania traces do like to lift, don't they?

[joemama99]

What a tremendous job-yes,you can fix anything!

[rcaman]

good work proud of ya.

[DaveWM]

nice save, way to hang in there.
