Singer TV6
 
This is the first TV6 I have ever worked on.I had been putting it off for years
as I figured this set would be a bear to work on.This set showed some signs
of life upon first power up,a faint wiggly raster and some hum from the speaker.
I was surprised to find that this set was easier to work on than I thought.
I changed every electrolytic capacitor in this tv,some were so deteriorated
that they fell off the board after unsoldering only one lead.
I did eventually get a full raster,and a picture,although very faint.That lasted
about a 1/2 hour,and then the screen flickered,and no more signal,but a good raster.After trouble-shooting the video "IF" stage for an hour or so,no signal coming out of the 3rd if stage,I decided to tap into the video detector(and audio) Basically setting the tv up as a composite monitor.After all,there are no more analog braodcast's around here,so the tuner is no longer needed.
This particular set now has a razor sharp picture,with plenty of brightness and contrast.Like I said,this was my first shot at a tv 6,maybe on the next one I may get the tuner functional,as I have 17 of these tiny sets(crazy,I know)

Kewl ! My TV-6 was one of the 1st sets I got after I got "Big" in this TV "Thing", 8-10 yrs ago..

I'll be watching this closely....as I recently got ahold of a beautiful little TV6U (with the little UHF thing underneath). It has about two thirds of a raster with absolutely no signal whatsoever. It DOES look like a bear to work with. Was even tricky to figure out getting the back off it. I did get a real SAMs photofact for it though...and just got an old "Castle" tuner subber I can use to poke IF into the thing if need be. I was able to inject audio into the volume pot...and video into one of the two shielded cables off the IF board (with that whole IF/Tuner side removed). I have not played with it much since. I need to find what the narrow vertical size is coming from so I'll have at least a clean "monitor" first. I'm pretty sure the vertical size had shrunk since I first saw a raster...so something is deffinately "going" on the poor little thing.

This is the COOLEST looking little set in my collection right now (It's sort of a dead heat with the Sony 8-301 though...which IS now working pretty good). I REALLY want to get the little TV6U to running though. It's the same size as all the little cheap chinese "Coby sets" I have on the credenza. I wanna put the TV6U right in the middle of 'em :-P

Awesome! I actually had mine shipped to a member here who restored mine to perfect working condition. Not only were caps replaced but also some resistors! When I got it, we still had analog broadcast here in Canada and I did catch some channels on it. My unit is complete (has all manuals, boxes and accessories. I even have original sales receipt!!)

This tv is now on display on a shelf by my fireplace in my living room. It's a cool conversation piece!

Nice TV! When I was taking first-year electronics in high school, in '93-'94, one of the assistant principals brought in one of those sets for repair. It was nearly dead and I feel like it was full of bad capacitors; but, my instructor wasn't too enthused about spending much time on it and he really didn't want me spending much time on it, either. When I graduated from high school in '95, that TV was still sitting on a shelf in the storage room.

Hi Leonk,

For the benefit of all here potential "lazy TV restorers", could you tell us who did the job. Would it be our long-time VK member & good friend Andy C. in Texas?

Thanks! & Best Regards

I'm sorta procrastinating taking mine on. I have the SAMs for it and everythng. I'm scared of it because it's very deffinately a problem with the tuner/IF board....and I've had REAL bad luck ever getting a tuner to go again if totally dead.

There is a thread elsewhere here on my little TV6U that describes my dead IF and or tuner. The small raster is almost certainly just a recap. I do get about 1/2 the screen if I inject video in place of one of the two (either green or gray) wires after removing the IF/tuner board...and audio into one side of the volume pot.

I'd say "ya done good!" Wow, is that board packed tight, looks like a fruit salad! Maybe not a "bear," but still tight quarters to work on.

Very good guess! Yes, Mr. Cuffe was the restorer! Top notch work, very pleased with the communication and handling of the entire transaction.

I do have a spare unit which I did a full cap replacement, and still didn't work. So I gave up and had Andy restore a second one for me. What I do recall from both TV's (this could be a common problem, or just my luck) is that they had nice bright raster, but couldn't tune / show any image. Just a bright grey screen, not even snow. Audio was also shot.

Every day, I thank the Lord & Little Fishes that I'm ONLY 75 miles away from Terry...(grin)

RATS!

Outbid on an ebay auction I was watching for a very complete TV6U. That seller had not tested it to see if it was a working set, but it was a VERY complete collection of all it's accessories...and the set itself would have been a parts set at the very least.

Thing went for $61...which outbid my $60 max. I shoulda put like $75.00 I guess, but there were no pics of the thing even lit up.

leonk 11-28-2012 05:39 PM

If anyone wants my spare TV6U (pretty complete with manuals, carrying case, etc) you can have it for cost of shipping from Toronto, Canada. PM me. It shows raster, but needs work.

AiboPet 11-28-2012 08:45 PM

PM'd !!

I'd love to see a donor set for this TV6U. I did this same thing with Kamakiri for his Sony 8-301 set...which HE got from Sandy. Nice that these "parts" sets can sorta make the rounds to make other sets "happy" again.

This TV6U set sorta scares me to get into it....because I actually LOVE how it looks even as just a "shelf queen"....so It'll be nice to still have one I can "look at" on a shelf..even as I have the "best parts" of both sets coming together to hopefully get one to go again.

From what I see of these, this "tuner gone" problem is actually the MOST common issue with this set. If I REALLY luck out...maybe I can get BOTH the IF boards to go again and be able to offer one up to someone. I really suspect one of the silicon parts on the IF board is gone on these. I remember having to clean the tuner with deoxit and "electronics cleaner" quite a bit to get the tuner to stop showing a short somewhere on ONE channel that would make parts on the IF board get REAL hot. I suspect whatever THAT problem is.....likely burnt up some silicon on these.

I don't suspect the tuners are dead...because the "raster only" shows up even with the UHF module switched in. I think this is after the tuners, and before the rest of the set...because I CAN get a very crude picture and sound by using the IF output pins and one leg of the volume pot.

The vertical size problem is some more pedestrian thing a recap should solve. I have about 1/2 of the vertical...NOT folded over or anything, just can't get much size.

Also, if you have that odd "bright on the right and darker on the left" raster....THAT problem seems to go away the second there is a video signal present.
