content: Tek 2215, 60Mhz o'scope, no probes, has power cable, has baggie that goes on top. DoesNOTwork!Got it off a friend a number of years ago, before I didn't know what I didn't know. Back in the day, it used to squeal when powered up and you could get a "beam find", but that was it. Now, nothing when power is applied. I've had it apart a few times since then, looking for the obvious bad cap, bad "part x", whatever. Never could find the correct service manual for it.If somebody wants it for pieces/parts, cosmetics, etc, hook me up with whatever it costs to ship it, and I'll be happy.Scale says it weighs about 15.5lbs, add a pound for packaging. UPS website says it'll cost between $20-$40 via UPS Ground in the US.Heck, for that matter, hook me up with one of Dave's uCurrent Adapters, and I'll ship it and throw a $20 in the box along with it!Seems like both are equally rare these days...

content: CRT showed a beam find the first dozen or so times I powered it on, but that was accompanied by the squeal...like anything probably from the power supply somewhere.So, I'm thinking CRT and the rest of the electronics are OK. Probably something in the power supply. I put an ESR meter on all the caps, looked for the obvious, meter'd a few things here and there. Nothing obvious threw itself out and hit me.I do know how to fix stuff like this, but this is beyond me, especially without a good service manual and schematics that match up.In N.D.

content: Well Holy Crap! Thanks.Don't tell me that was the first link of a Google search...'cause I didn't get that memoAnd I'm usually the first person to point out LMGTFY.meh...I'll take a quick look around, but I've already got a 2246A and a SDS7102. Somebody else without a 'scope might get a lot more use out of it than I will...if they can get it fixed.

content: So if skimask doesn't end up fixing itI have a proposition. I would take it for the price of shipping, take a look see inside and try to repair it if I can find the right parts. If the repair ends up outside my budget or I cannot fix, I'd be happy to pass the deal onto Tom. Does that sound good to you all?

If Skimask agrees, of course.Skimask, my apologies. I did not correlate the "N.D." in the title for the state. I should have picked up on that.

content: Ok, so now that I'm thinking about this more, I probably won't be able to fix it simply due to knowledge and tool difference- you have an ESR meter, and have already tested much more than I could with the current tools I have. So if Tom/others are still interested I'm very much considering passing it off to him/whoever is next if he doesn't want it... Unless you have fixed it or determined the problem.Another thing- I haven't looked at the schematics but couldn't squealing indicate a transformer problem? Doesn't it happen when a wire becomes loose? My guess (I'm no EE), is that one of the transformer coils broke...

content: Well, yes and no, but it's generally not the transformer itself causing the problem. Transformer making the noise, yes, problem, no.It's usually one of the caps in the SMPS going south. High ESR, basically whatever cap ends up not being able to charge/discharge fast enough to satisfy the switching of the SMPS.But with that being said, I went back thru and eyeballed everything I could see, put an ESR meter on the bigger ones, measured out the smaller ones, removed/reinstalled a bunch of them. Couldn't find any that were bad....then again, I didn't spend a lot of time on it.I took it apart as far as needed, placed all the screws and that support bracket around the PSU in a ziplock baggie, and put it inside the 'scope.And that's the way I'm shipping it.I'd kick myself in the nads if it was a dead simple fix and I missed it...but, as said before, I've got 2 other 'scopes. I'm good.I prefer UPS since it's practically right down the road. Don't want to go to the local USPS office as it's ALWAYS full and this mongo doesn't do FedEx.Whoever wants it can go on the UPS website and look at shipping for ~20lbs, box is 19"L x 17"W x 9"H, from 58701 to wherever. Let me know here, as soon as I see it in my paypal (I'll PM my address), I'll run down and ship it off.

If it wasn't so damn cold out, I'd be thinking the same thing.And ya, North Dakota. You betchya... (I'm originally from south/central Minnesota. Somewhere in there, I think being born in Minnesota gives a guy a legal right to say "You Betchya")

content: Where does the list stand on this?I'm into troubleshooting and think that taking a shot at an O-scope might be fun. To be honest, I've had less success stories than failure stories, but I seem to learn something every time.

content: K, here's where I stand on this...Am I a professional electronics genius? Probably not. Do I think I am? Sure...Why not?Would a true professional that's been tinkering with electronics for 50 years think so? Hell no...Have I been messing with electronicable thingies for awhile? Ya, since I was about 9 or 10, that's about as early as I remember when my parents bought me a Radio Shack 150-in-1 electronics kit. So, that means I've been at it for about 20+ years, but you gotta subtract about 10 years in the middle somewhere when I was stuck in the bar-hopping/getting-some mode and kinda put computers/electronics off to the side and just worked and partied.Jist of the story...(in my mind)...If you can't draw out a block diagram of an SMPS from scratch without pulling up a datasheet, If you can't visually pick apart a PCB, figure out the general layout of the board and what section likely does what, If you can't take brand X MCU and make a blinky LED, If the majority of stuff you do is "script-kiddie" stuff or at least the hardware equivalent of a "script kiddie"....If you don't know what a "script-kiddie" is, or you have to think twice if you are a "script kiddie" or not, then this probably is NOT for you.Let's face it...The overwhelming vast majority of posts around here are from newb script-kiddies looking for the obvious information (by obvious I mean Google-able) or want a bunch of spoon feeding from somebody to finish their homework for them.I see a lot of "I bought one of these thingies off ebay and I saw a video on youtube on how to fix it but that fix didn't work so how do I fix it" type of stuff.Is this o'scope one of those types of things? meh...could be. I can overlook the obvious just as easily as the next guy.If you're one of those guys that recently saw a video on youtube or a blog entry somewhere about re-capping a monitor and that fixed the problem, this isn't for you.Once I get rid of the item, I wash my hands of it. I've had it happen before where I sold something that didn't work. The clown that bought it came right back after he got it asking all sorts of questions about doing this/that/the-other-thing. I'm done with that. I've got better things to do.

content: I'm not keeping any list. There is no list. Never was a list. I could care less who takes it. If there was a list, there would only be one person on it and the list would go away as soon as I saw the shipping $$$ in my paypal account.As far as who my last post was directed at, well, nobody in particular. The point was that there's a ba-zillion people around here wanting something for nothing (just like the rest of the 99.9999% of the population of the world) and this 'scope probably is NOT going to be that something-for-nothing piece of equipment. Just pull up the recent posts and count how many of them say something like "Where can I get the cheapest enter-piece-of-gear-here". I'd rather send it off to somebody that's genuinely interested and more-or-less capable, not some punk clown kid looking for a freebie...which there seems to be an extreme excess of these days...

content: Quote from: Skimask on November 24, 2013, 06:33:59 amI'm in, for $40, it's worth it to me.I know what you mean by the estimator being only that, an estimator. I used to ship a lot of custom engine mounts I made for a particular swap a number of years ago, and found that sometimes it was high, sometimes it was low, so I did what you do, round up. After a while I just made a set shipped price because I got an average of what shipping cost, and used that to make it easy for people to pay, and less messages back and forth, but I digress on that.Anyway, PM me your Paypal address and I'll send you payment.ThanksAlso, I think this applies here:
