    Re: Post your worthless and/or pointless repairs

    I'm unsure if this is actually the most pointless fix I've ever made, but it sets the bar quite high, even for my standards. At least I had it for around five more years.

        The tape was there since almost forever, after I accidently stepped on it once. The more recent Sunday-evening fix was the external power switch, after the original one went up in smoke haha

            No, not pointless or worthless at all, you saved it from the landfill (unless you paid more for the switch than buying a new heat gun... then it would indeed qualify)!

            However... definitely qualifies for ghetto fix in any circumstance!

            "vollgas" and "standgas" are cute for reading as straight English, but probably quite typical for German...?

              It is similar in Swedish.
              It means full throttle or idle (speaking about a cars combustion engine).

                  RAKS ED-X 60 audio cassette repair

                  Ever encountered an audio cassette without screws?
                  Well, they aren't actually that uncommon, I suppose... at least back in the day (Otherwise, can we say ALL cassettes are uncommon at this point? In fact, does anyone even have/keep cassettes anymore? )

                  So where am I going with this? Let's turn back time [to the good old days] just a little over 25 years ago - mid 1990's. Little 5-6 Y.O.me back then used to love taking a cassette tape and spinning the reel inside it with a pen or pencil while listening to music. I don't know why I found this to be so magical (hypnotizing even? ), but that's what I did.

                  Long story short, the tape on one cassette somehow fell on the side of the reel. I realized what happened and switched to the other reel to spin the tape backwards, hoping the tape would pull out and straighten again. It did. But then some days/week/who-knows-how-long later, the same thing happened to the same cassette. And this time, the tape didn't straighten out, even after reaching the end of the reel (the cleaning tape.) Instead, it kinked and partially pinched on the side of the reel of the tape. No matter how many times I rewound that tape, both by hand/pen/pencil or on my dad's tape deck, the kink never straightened itself. And because it was partially pinched on the side, it added considerable friction between the reel and the case. As such, this cassette would now drag / play slow towards one side. It drove me nuts for many years when I was a kid. But I was too little to try to fix it back then. And my dad said it is not fixable, because the cassette's case didn't have screws and we wouldn't be able to put it back together.

                  Fast forward 20-ish years later... and I found this cassette stashed in a box with other tapes that I thought my parents had gotten rid of a long time ago. The nostalgia kicked in and I wanted to play this cassette again. It was a copy of Queen / Freddy Mercury – Greatest Hits, and probably one of my most favorite cassettes, along with Foreigner and a few others.

                  Of course me being who I am today, I knew I could fix this cassette finally after all these years… and so I did!

                  Since the cassette came with no screws, I had to split it open with a razor / sharp knife. This was pretty easy, actually. So was straightening the kinked cleaning tape (sorry, I forgot to take pictures of what it looked like when it was kinked in there.) But when it came time to close it, that's where I had to go just slightly ghetto with the fix. I didn't have rubber / contact cement to glue the cassette's case nicely. And PVC glue probably wouldn't have worked, since it looked like PC (polycarbon) plastic, which doesn't glue well with PVC cement. However, if there is one thing that works pretty well on PC and acrylic, it's hot glue.

                  5 minutes later with the hot glue gun, and it was all back together.



                  Even with cassette tapes now being vintage and probably having higher value than they did 20-25 years ago… I think we can all agree this was quite a pointless repair.
                  However, I still think it was totally worth it to see it play properly again. And that it did.
                  Nostalgia is such a satisfying feeling sometimes.

                    This was "media recovery" way back when.... just to restore a cartridge back to usable shape so that data can be recovered.

                    Not a pointless repair if you don't have a copy of the media elsewhere, else probably cheaper to recreate a new tape.

                    That being said, what would happen if someone winded the feed spool backwards, practical joke for way back when?

                      It's only pointless in the fact a FLAC copy can be downloaded faster than you can do the repair.
                      To me, repairing one of your favourite vintage tapes to be used again, is the very opposite of pointless.

                        I still do , and it's worth it , especially when mines are of the highest possible quality , like ferricobalts and chromes ..Their quality was pretty equivalent to Vinyl discs .

                          I still have a small pile of compact cassettes, mixture of regular and chrome tapes. Unfortunately nothing worth listening to since they're blanks.

                          One of my cars has only a tape player for removable storage and it's bust, so I end up having to use RF. Oh well.

                            I don't, but it's nothing special, nostalgia aside - just Queen, Greatest Hits collection. Like diif mentioned, it's probably faster to grab a copy off of the internet - be it in digital format or just buying a used CD (I still do the latter, though locally now.)

                            Heheh.
                            I thought about that once when I was a kid.

                            What happens may depend on the deck / machine the tape is played on.

                            I have a few off-brand Walkman / "personal" cassette players that don't have Rewind function (LOL!), so there is nothing that rotates with the feed spool.

                            On my Marantz SD4000 deck, however, the tape counter mechanism is driven via a rubber belt pulley system. So if it spins backwards while the tape is going forward, the tape counter will spin backwards.

                            Yeah, isn't it somewhat sad how (too) easy it is to do certain things with the internet now? Things that before, we'd have to spend a considerable amount of time and knowledge on. I mean, it's nice and convenient... but also not as much fun, IMO - not for a kid, anyways. Glad I wasn't in the generation to grow up with a tablet and phone in my hand 24/7.

                            I remember when my dad taught me how to make my own mix tapes when I was ~5 or so years old. Certain days, I'd spend all day listening to the radio, waiting to record songs I liked. And of course, one had to be quick to hit the stop at the end of the song before the radio host started talking or cut the song a little early... or fade it out gradually before that.

                            Yeah, a properly recorded FeCr, CrO2, or metal tape can sound pretty decent. I have a few of these as well - in the same box as the RAKS tape shown above. Also have one with a ceramic casing. This stuff is worth crazy money now on eBay, LOL. They all worked too, last time I checked (3-4 years ago.)

                            Is that one of those 3.5 mm / flash drive / removable media to RF car transmitters?

                            I bought one some years ago to complement my CD music collections on long trips between college and home. The thing couldn't transmit to a blank station even in the middle of nowhere on a highway. I ended up opening it up and soldering a long piece of wire to the antenna output. Then it had no problem over-powering just about any radio station. Even better, I found that its PLL frequency-aliased (or something along those lines) and was transmitting to several other random FM frequencies too, but with a little less power. Definitely must have broken its FCC approval, if it ever had one.

                            Hmmm... looking at pictures of stuff I posted, I don't think I posted my "modified" RF transmitter. Worthy of the ghettomod thread, though.
                            Gonna wait for some sunlight one of these days and see if I can snap a few.

                              I have a FM transmitter that was completely analog that was not PLL driven, this thing drifts really badly. However my FM transmitters that are PLL locked (one cellphone with built-in transmitter and a few cigarette lighter FM transmitters) and can tune the whole broadcast FM band have been much better, though I always use an unused station. With the unused station, they worked just fine.

                              Technically even if it splatters (i.e. can receive on more than one frequency), if these pass FCC part 15 rules, they are still legal. Unfortunately it appears that anyone within 200ft line of sight may still get unintentional operation. Should be much less than that if there's something in the way...

                                Samsung LNT4061FX-XAA 40” TV

                                As usual, I’ll start with a bit of a story. I picked a Samsung LNT4061FX-XAA 40” TV up in December of 2021 from next to a dumpster near a condo in my area that I pass by on my way to one of the grocery stores. We had rain forecast for the evening, but I left the TV sitting there, hoping someone would take it (besides, I was skeptical if that condo was clean or not in regards to roaches and other pests.) However, no one did and I returned for it later in the evening. By the time I was there, the TV got rained on a little. But figured I’d still pick it up. Worst case, I’d pull the boards and scrap the rest.

                                Once I got it home, I wiped the moisture from it and then put it outside again, covered with a trash bag to prevent it from getting rained on more. The next day after the rain stopped, I pulled it apart and inspected it - no roaches or anything else indicative of pests hiding in there. However, the TV did have a thick coat of dust with very strong scent of air freshener (probably one of those households that has an air freshener plugged in every socket on every wall, LOL.)

                                Upon opening, I immediately spotted a bad cap on the PSU – a SamWha WB, 25V, 1000 uF.


                                However, I decided to test the TV as-is, just to see what it did and if the screen is OK. Interestingly, the TV worked, despite the failed SamWha WB cap. The bad news is that the screen wasn’t exactly good… though not broken either. It was this:


                                … basically a thick row of dead / dying / dark pixels on the bottom of the screen. Shame, because it is a 1080p TV, despite being older, not smart, and only 60 Hz refresh.

                                More pictures of the issues with the screen:





                                At first, I though I’m not going to waste any good-branded caps on the PSU board. Just replace the one failed SamWha cap, take pictures, and donate the TV as-is (well, jury’s still out on that.) So for a test / quick fix, I replaced only the single failed SamWha cap above with a Jackcon LHK, 25V, 1000 uF that I bought back in 2017 for cheap when I worked in MicroCenter (was going to use this cap along with a few others to fix a recycle bin –rescued LCD for my workbench there, since I couldn’t take the monitor with me… but I ended up not having enough time before I left that place.) Believe it or not, this Jackcon cap was still showing good ESR and capacitance after 5 years of storage and never used (not that I’m making any claim here for Jackcon to be considered good or even OK, but just worth noting they can be used as a temporary/test fix.)


                                And here is what the failed SamWha WB cap read like:


                                With the SamWha cap replaced, I then finished the TV by cleaning / wiping all of the plastics to get it ready to give away. And again, it’s a shame about the screen defect, because otherwise look how clean the TV came out after cleaning:





                                What’s even a bigger shame is that I saw a ton of working 720p and 1080p TVs being given out for free (or as little as $10-20) in the last year, all the same size or even bigger than this Samsung, with no screen defects. Many came with remotes, too. I guess no one cares about 40-50” TVs in my area anymore. Looks like they fall in a size that is too big to be a kitchen TV and too small to be a main / living room TV. Mine being without a remote and with a screen defect seemed just not possible to even give away for free. The most ironic part is that I don’t even watch TV! (And I have plenty of 19-24” LCD monitors, which is my preferred size, so not much use as a monitor either… but jury’s out on that as well. )

                                Then one boring rainy day last spring, I thought, “Ah, what the hell!” - in for the penny, in for the pound / dollar / [insert your currency here]. I decided to do a more extensive recap on the PSU board, since I already had some of the values in stock.

                                And I did. The repair is posted in the thread below (figured I’d split it in there, since I put some cap info and whatnot.)
                                https://www.badcaps.net/forum/showpo...55&postcount=6

                                So what am I going to do with this TV? No idea yet. Don’t think anyone will be interested in it, but will see / try again. I bought a used remote for it for $6, so it’s a complete set now (I guess that’s the nice thing about older Samsung TVs – remotes are abundant and cheap on eBay.) The TV is currently set up as a monitor with a spare PC I have. It doesn’t see much use, as I use that PC only for testing software or burning DVDs once in a while. The TV also doesn’t look too bad when used for watching extended wide screen content, such as shown below, where the screen defect is not visible at all:


                                So all in all, it’s usable. At least for a little while longer, I guess that would be another TV saved from the landfill. Good enough for me.

                                    Mainly would like it working again as I'm currently using two 19" 1280x1024 monitors right now... a full 1080p display would actually be an upgrade...

                                        Do you mean blanks or pre-recorded type II / IV tapes?
                                        Type I = Ferric Oxide?
                                        Type II = Chromium Oxide?
                                        Type IV = Metal Particle?

                                        Metal Particle tapes aren't exactly a rare commodity even, thought that all DAT tapes, 8mm video tapes, etc. were all MP. Old VHS tapes were ferric oxide, so those are dime a dozen...

                                          There is more complexity to types :

                                          It's not the matter if they're re-producted now or before . It's if you keep their original status .
