Woohoo! Sharp 25R-S100 with remote by the side of the road. (Updated Goodwill find!)
 

Well, it's not what I'm hoping to discover, but it seems that fate has taken notice of my desire to acquire some TVs at least.... :scratch2:

:banana:

Model: R25-S100, manufactured in 2002.

Sign on the face of the tube says "FREE FREE WORKS" and the remote is taped to the top. I just lugged it in from the car (At 28, I'm beginning to think that I'm shortly going to be too old to live in a 2nd floor apartment.) and haven't powered it on (and won't, yet, see below.) but nothing seems visually wrong with it.


It couldn't have happened on a better day either. The YL is coming over for more electronics knowledge acquisition this evening, and I just purchased a shiny new Rigol oscilloscope (which will get it's own thread shortly.) and was planning to hit up the thrift stores for some simple consumer electronics items that make for good probing, but now I'm going out to the thrifts to find a bigger or at least sturdier workbench with enough room for two people to share. And a few $3 transistor radios and alarm clocks too.


I can only hope I'll find something with more than "one" "tube" in it someday.


I like my 19" 1989 Zenith System III just fine, I don't need this 24" (or 27"?) but when it has served it's current purpose, I will pass it on to someone who will actually use it. The last time I actually had my TV on was to watch the winter Olympics. I'd say I average less than an hour per year of actual TV watching in my own home.

Would NOT have touched. Worked on them when they were new, 20 or so years ago. HATED them. Hot chassis, flimsy single board--NOTHING to attract me. They often get vertical problems, nearly ALWAYS just caps. Flys seem to be a bit better than the ones from a few years before. Tuners also sometimes go bad/get intermittent. If you like it--good, but I will save my collecting energy and funds for tube and MUCH earlier SS stuff.

I wouldn't have bothered either. Not old enough.

I reckon you'll get more picky as I did with time and the arrival of nicer SS and perhaps hybrid sets. I've junked more than I actually have right now. Never did have an interest in anything that recent though. Just last week I passed up a CTC203 set by the curb within spitting distance of my place. Not even worth getting for parts to me.

If I were you I'd build a workbench. Easier to get what you're looking for and much cheaper.

Oh yeah, I _only_ picked this up because I needed something to tear down as a teaching experience for the YL. I plan on it surviving the process and I'll give it directly to someone who actually wants it and will keep and use it. If I make $10 on the deal for "checking it out and servicing/adjustments." that's cool, if not, I got the value I needed out of it. It was all :sadwave: as I dove past. (I was actually thinking: Maybe one of these trash pickup piles has a microwave in it.) Had it been any of the various funai/san-sui/Coby brands, I'd have completely ignored it. Same goes for a similar vintage "RCA" Which is funny, I like telling people "RCA is now a French company (Thomson) that has manufacturing plants in Mexico. Go 'murrica!" I'll at least stop and prod anything Sharp/Panasonic/Samsung/Sony for free, but I'm not stopping for anything completely without worth or redemption.

I just scored this at Goodwill. Oh dear god, never again will I forget that going to *that* Goodwill outlet on a Friday (People get paid on Fridays, I've been told.) is a terrible idea... Because holy crap, we're talking bluebottles on a fresh cow-pat type frenzy!

UHF still had 70-83 back in 1986?

Fairly great condition overall. I'll find out tonight what functional condition it is in. Presumably someone at goodwill powered it on, and made sure there was static on the screen and the radios worked.

It has a degauss button on the back, that's a very desirable feature in a portable set I would think.

I think it is close to being "vintage" and now I have the added peace of mind that the YL is much less likely to suffer serious injury during the lessons. More points to probe, too! None of this "Here's the RF in, here's the tuner chip, baseband comes out of that and goes into this chip, and hey here's the color gun signals, audio goes that-a-way, mind the flyback lead, dear." crapola. I'm expecting it to be mostly discrete chips for the different functions along the way.


My new pride and joy!

Hmm, anybody happen to randomly have a service manual or schematic for the TC7 on hand? So far everything I've found is for-pay or for a modern LCD flatscreen that has "TC7" in the chassis number.

Booo!

Whooo Hooo ! !

Good for you ! ! ! I am a Sharp Fan, I always pick them up, never had a bad one....

I think it's just my luck cause I worked for'em light years ago....

I think those sets see me comin and know I like'em and they just perform better for me! !

I like that cabinet design, where they make it a point to have the cabinet hug as close to the tube

as they can, even around back.... Makes them much more manageable..... I got a Sanyo like that too..


Is that a digital scope....? Working....? or to be worked on....?

And yah, I noticed sets get tossed out with the remote taped to the top now.... I guess they want someone
to pick it up, or they gotta take it to the R-center.... So are they like, "being kind..." or just
deciding not to be a-holes......?

I was gifted an RCA version of the little Emerson this AM. Radio seems to work, TV is dead. Hey, it was FREE, what can I say ?

I threw away a 25" Sharp just like that, manufactured in '98..It worked but I couldn't justify taking it in a move. Someone took it the same day I put it out..likely a scrapper. They're pretty reliable sets, but the CRT was soft in a few I've seen--it wouldn't focus until about 20 seconds after power up.
My '80s Sharps are good sets IMO..I have a '84 13" with composite input and remote and an '82 with remote and an LED tuner readout. Only gripe with these is that the cabinets are cheap..If you play the volume loud on either one, there is bad rattle even after tightening up all cabinet hardware.

Brand spankin new! :yes:

Rigol DS1104Z. I have other scopes, but nothing that is actually close to calibrated enough for modern small-signal work I do. Hell, this thing even does all the math/trig for me, I'm going to get rusty with that... Pass me the naval jelly, would you?

For free, you can't go wrong! Hope you get it working.

The idea is to have fun & learn. Aint no Zenith flat chassis or
RCA 2000 but the price was right. As far as Sharp sets go I
will toss a bomb & see what happens. IMHO as usual....

Sharp sets are not a premium set & never were meant to be.
They did slip in a few gooduns now & then.
Tube sets were crappy, on a par with GE.
Early solid states were not bad but a pain to work on.
The next batch defined junk, remember all the RTRNF00**CEZZ FBT's
that went up in smoke ? Thats what you get for an under $200 19".
The set in question was not bad to deal with. All I remember
was the little square blue on/off relay that went bad L&R. Other
than that for the $$ it wasnt as bad as other "value" brands.
And one other thing with Sharp & many other of that era.
Without the OEM remote they are useless.

73 Zeno:smoke:

Turns out the TV is fine-AC cord/plug is "Spotty"..Mine was made in 1991.

I seem to remember that these sets also seem to develop problems in the 12V. ckt, often causing a dead set. Seems that often a zener would short and kill that line. Not a hard fix. Also, the standby tranny sometimes got killed, I guess by a surge. Again, not a hard fix--IF you can get one. As stated before--the blue relay and the supression diode that often would short across the coil--causing a dead set. ALL of those were easy fixes.

All in all--these are not hard sets to repair. By now--you likely will need to replace a few caps in the vertical ckt. Not sure if this one uses a chip out for vertical or discrete outs. ON the somewhat unlikely chance of a bad fly--I think they will be available and are NOT hard to change--nor too expensive. As stated--the generation before these ATE flybacks--particularly the 19 inch sets !! IF your tube is good (kinda "iffy, I saw nearly NEW sharps os this era with VERY bad tubes--and a LOT that had decent tubes too..), it IS a fair set to repair and flip.


They just do NOT float my boat...too new, too boring, too common. I sent one like it, along with a JVC and a MAG set of the late 90's--to the dump when I moved my garage....need the room for vintage stuff.

Zeno, I'm with you on that one. I'll throw out a bigger bomb... ( ready to duck and take cover.. haha) IMHO Sony is not one of my faves either. They started out with a premium product ( and I am a HUGE fan of the Trinitron tube), but in the early days, they were a bitch to get parts for if you weren't an authorized service center. They had a "tude".. Then towards the late 80's they started shipping out crap, and rolled with it because they were SONY. I look for older Trintrons, but have discovered that it's "good luck" finding a decent tube on one.
