Orion is a cheaper brand; but, not as bad as Funai. Like other companies, Toshiba figured out that they could outsource production of their TV's cheaper than they could build them on their own.

Talking

Well, I would like to thank you all for helping me out. The TV seems to be back up and running like normal. I'm going to run it for awhile tomorrow to make sure its good to go before I put it all back together. Anymore suggestions of things to do while it's apart?

Went over to Radio Shack this afternoon because I needed something and I found (online), that they supposedly carried the Lytic cap that I needed.(35v220uF) They actually did! and the guy knew what I was talking about!! Little expensive but no wait for shipping-So why not...
Anyway's I pulled it apart at my table in the basement, and proceeded to discharge the CRT. My dad was all pins and needles when I was doing this... The CRT didn't even have a snap to it when I discharged it. I vaccumed it all out, including the back casing. A lot of dust after about 14 years...
Pulled the board out a little way's and just looked it over. I Desolderd that cap, then put the new one in. Then I re-soldered the connections of that vert. chip, hooked it all back up, and volla

Got some photo's if anyone care's
Here's the underside of the board http://i467.photobucket.com/albums/r...psea86880b.jpg
Close up of my resolder job http://i467.photobucket.com/albums/r...psfddbb1cc.jpg
The repairs made-resolder and cap

Back of the Television on my table

New Capacitor

and The Result!!!


Apparently the chip was fine... or slowley on its way out, without currently showing any issues... Should I worry about getting another? Everything else seems to function as should and was plesently surprised that my custom settings were still in its memory for playing my PS3.

Thanks again for the help!

Get to it Squirrel! Don't keep running it if ya don't have too. Or something like this may happen to it-mabey worse. Hell, it only lasted with the line and compression at the top of the screen for 2-3 day's, then poof...Horozontal Line

Hmm, mabey I should pull apart my 20" Zenith... That's got 10 more year's on this set, and it's never been opened either. Whats worse was that it lived in a kitchen for 15 years, then a garage for half a year Mabey that's part of the reason why it's got a greenish tint and bad focus, and some stretchage issues.

Good pictures !

Yah a lot of people here don't like the last gen crt sets, but they do represent the best
and worst of the crt years..... Best as in for the size, they make a great picture, low
power useage, very compact circuit designs, and for the most part pretty reliable.
The worst of it is the cheap parts used made many die too soon, and of course the
gov's campaign to get the ekonim'e going "replace all yer electronics regularly - It's all
got lead in it!" BS kinda puts a bad taint on keeping crt sets... You know the lead is
gunna leak out and make yer kids dumb....

Ran mine regularly for the last 2 days... Fri-picture collapsed, turned it off then on,
and it finished the day ok.... Sat. no issues at all and it ran longer..... Now I'm thinking
it's a bad solder joint..... I'm gunna run it tonight and whack it a few times, see what
happens..... Otherwise I got another set to put there temp. till I work on this
one. Move all that stuff, the couch, wires converters, VCR's and give that
area a shot with the vacuum - scare off those dust bunnies....

Good to see you got that set working- Looks very good !

You're right Username1......and mine has also a small circuit and it's running very well for a Toshiba made by Orion..this set uses a Orion tube, nice picture anyway...

Zack, you made a good job on yours nice picture too.

I have a Funai, and two Orions. One Orion is a flat tube, I don't care for it as it's out
of focus at the edges, The Funai is an Emerson, and looks pretty good. My Sanyo
is all Sanyo as far as I can see.... Sanyo tube, and Sanyo parts and ID on chassis....

Of course If it was outsourced and not identified I can't tell.... I think it's a 2001 yr.
I gave the Sanyo a little extra TLC when I got it, had to replace a cap, and redo the
convergence due to the white glue coming off.... Replaced it with clear silicone after
conv. and focus, gray adj. found the secret menu and touched up a buncha stuff.
Now color, and B&W shows really look great. It's a good cheap tv that performs well...
I would pick up another if a free or $10. one came along...

Well, i've never seen a Funai so I don't know how looks like this set. Don't have Orion... however i have an old Sanyo..... At this day my Toshiba (orion) play very well. $10 for and old tv set is not expensive and correct. ... It's hard to found the secret meny when you don't have the right remote control...

If you get a set and it works well, you can often type the model number into
ebay and the sellers who specialize in remotes often have them listed along
with the tv/vcr/helicopter/time machine they go with.....

The secret menu is often accessed by some odd combination of front panel
buttons along with pulling the plug from the wall while holding a fan above
the screen - odd stuff, but it's not a button on the remote as far as I know....

In the case of my Sanyo it was written in the service manual, which I found online,
It gave access to screen controls, vert size, drive controls.... stuff like that.

Layout was cryptic and numeric, you had to have the manual which had the
item written out, like Green Screen Adjust. and it had a cryptic ID like GR1
and you scroll through till you find it by number or ID then next to it
was both the present value, and it's preset, which you could reset it to if
you wanted. It saved when you exited. All these modern sets have this
menu, some you can find on google by asking "your tv" and "setup menu"
There are a few pages out there with just these menus on them, and how to
get to them..... Just be careful, write down what you do, and do only one
or two at a time.... There is no confirmation for it all, its not home owner
friendly, no warnings etc.

Well, I put the set back together after running it for about 5 hours without any problems. Running nice and cool too! Got it set back up where it belongs just in time for the new episode of The Simpson's lol

Thanks Squirrel. Hmm yea, I must agree with ya, but would early 2000's be considerd as last gen? I'd figure that would be the one's from the mid-late 2000's when CRT sets were being phased out. My dad got one of the later one's (20"Emerson) and I never thought it was built the best. I could probably tune it up some but he don't care and it's reliable...even with it's crooked assed picture
Wow, sounds like you've got lots of work to do just to move your set!

Thanks Marco-nix. Yea, I was kind of surprised at how small our Sanyo's circut board is. It runs the tv, and it also has the menu and technical controls all built in and somehow can "remember" the settings.

Never heard of Funai and wasn't Orion a film production company? Hey, is the Sanyo your taking about here, the same one as the one that ya said was having foldover issues? Secret menu huh? Sound's interesting After all these years I think our Sanyo may have dulled some. I wonder if I can sharpen it up... wording is hard to read when playing the PS3 on it, and the 20" we were using in its place for the last couple of day's didn't look as bad as I expected(since it was a smaller screen and I could actually still read the wording from the PS)

Huh, not sure now if I should bother cheking into that or not now. It looks pretty good but I feel it could be better.

Hey guy's, I was wondering. Since this cap went bad, how long will all the other cap's (made by the same company) most likely last?

It's no telling about the caps.... Faults can come from a design goof, or cutting corners
on quality parts, not allowing for enough "space" between rated, and working conditions
for any of the parts. Can apply to heat, or voltage ratings. Accepting bids on parts from the lowest bidder....

If you feel your picture could be sharper, there should be a focus control on the flyback
transformer, it's the thing with the red wire that goes to the picture tube....

The "pump up" ckt...has ALWAYS been hard on capacitors. It is one of the first problems to surface on tv sets on the modern SS area--after bad connections. The smaller modern caps get--the more failure-prone the seem to get. I would not worry too much about other ones --yet. I do NOT think Sanyo had a "chronic problem" with electrolytic caps--like its did in their sets.

This repair is a great example of how to fix almost any
vert problem in any set from the mid 80's on. In fact
I only remember a few that wouldnt be fixed by following
the problems pointed out. Thats hundreds of sets......

BTW your set has an RCA CRT the best of that era.

What was or is the "pump up" circuit....? Never knew that term....
I've seen the RCA flyback start circuits, the old doublers, and a few others,
what are the characteristics of the pump up design.....?
And who's set has RCA picture tube, and are they directly labeled....?
How can you tell...? Did this differ between the21", 25" and 27"....?
