I replace a worn power socket on this laptop after mains power started dropping out randomly. It requires complete disassembly to remove the motherboard and cutting out the old socket so a new one can be soldered in. I had to mute a few parts because my camera is in need of a new external mic socket it seems and makes a terrible noise when it plays up since its digital junk that cant just lose ...

Glad to come across this! I'm just fixing one up for fun. How did you resolve the motor noise that was sounding when you first tried turning it on? Mine has the same issue
i just bought one at goodwill for $8 the radio works cassette does not. There were two springs inside the boombox where the cassette buttons are they & look like battery terminal springs but the battery compartment is not missing it's springs so I'm not sure where they go maybe to the cassette deck somewhere.
Why does the engine spin when I don't press play? I have the same one and it makes a spinning noise even when stopped...
You learn something new every day. Never knew Hanimex were Australian - we got their stuff in the UK as well and I'd always assumed they were just some Hong Kong company. They were mainly known for cheap-and-cheerful cameras here.
Cameras and slide projectors seem to have been their main products back in the 70s and 80s, but there is a reasonable amount of their consumer electronics around in Australia, mainly small audio devices and the occasional TV game. I have a fluorescent clock radio here somewhere. Just remembered I have a 5" colour tv clock radio and its also got their brand on it, they were also sold under around 5 other brands.
@@StevesElectronicRepairShop Now you mention it I do remember the slide projectors often carrying the Hanimex brand name as well. They did have a reasonable reputation as I recall, very much budget but not nasty. I think my confusion with Hong Kong came from the fact that their stuff always seemed to be in direct competition with the similar-sounding "Halina", which (I've just read) was indeed a HK company (Haking). Possible even that Hanimex's cameras were rebadged Halina as they did seem quite similar. Did see the odd Hanimex video game but most of the Pong machines we got were branded Binatone, who were a very well-known UK manufacturer/distributor of budget electronics who were, for a while the biggest seller of phones and answering machines here.
I got 2 for you if you are able to check them out, Ones a a fujitsu ten and the other is some generic brand from the 80s/ 90s Plus the tape you dont care about! ahahah I love That song by Flowers
Its a classic Aussie track that one. I liked Ice House as well.
Hey Steve, I sent you an email on Aug 11 - not sure if you got it? Cheers.
8/20/2024 me again: I must add that the old belts left an extremely sticky black goo on the sheaves (and on my fingers!), and I used several cotton swabs (Q tips), pinched flat with pliers, dipped in alcohol, around and around in the grooves of the sheaves, to remove the goo.Then dried with clean Q tips.
I have done a video on that horrible goo. Acetone dissolves it really well and gets it off your hands as well as the mech.
8/20/2024. I used your video figuring how to install two bitsy belts on my Sony CFM-165TW Radio-Cassette Player, one from the motor (to the large sheave or to the smaller sheave? I chose the larger); and one from the smaller sheave to the black "solo" sheave. I have a Sony CFM-165TW. After reinstalling everything best I could remember, I couldn't believe it worked, plays forward, reverses, and stops. Thanks for producing the video.

Cassette tapes roasting on an open fire, bad cords heading to the bin, though it's been said many times many ways, Steve can fix it for sure
Good work 👍.
I found the same tv at the tip about 5 yrs ago in very good condition used it to watch videos had it stored until recently and moved house now I've set it up with the VCR and hooked up my DVR player to it now using it for watching tele got a good clear picture and works well for vintage tv set
They were a good TV. I think they have the blue tinted Opticolour tubes which supposedly made a difference, though it was hard to tell if it was much of one.
Hello. How can I find your contact details please?
Very nice valves/vacuum tubes! Have you done anything with them since you got them?
I did dig through them when I needed a couple for valve TV diagnosis, but the types I wanted werent there. Luckily a rotted old valve TV I saved had what I needed.
Hey man seems like you’re very knowledgeable about this. This actually helped me a lot. But I have an issue on my lasonic Trc 975 book box. Where the speeds on the slots are different to one another. Tape A is perfectly fine ! But tape b is slooooowwwww. There is a 1k ohm trimmer pot that I replaced. But if I adjust it so that tape b plays at correct speed tape A plays too fast. I have no idea why this is happening. I replaced all belts in it. It’s driven by one motor. Both decks. Will wrong belt sizes cause speed issues ? And shouldn’t that trimmer pot control speed between both decks evenly ? That’s the mystery
I think I had a similar issue in a boombox recently but cant remember what it was. May have been the Mitsubishi one. Belts shouldnt cause unless very tight, it but possibly something like the reels having an issue may cause one capstan to slow if the reel belt comes from the capstan, though in theory it should slow the whole motor, but it may not always be the case. The problem is you cant test it easily as removing the belt will make it chew a tape on that deck.
Tassie?? Really?? North or South??
I've had a Sears audio appliance with record player, am/fm radio, and two tape decks--one for recording and playback, the other for just end to end playback, no reverse. The single end-to-end cassette player has not worked for over a decade. The record/play cassette player stopped closer to 5 years ago. It's always been my goal to give both cassette players an overhaul and see what's up. Thank you for giving me both a roadmap to the mechanism and where typical failures happen. I'm looking forward to having this back in working condition!
Good luck with it. I have quite a few other cassette and boombox repair videos. They might be worth a quick look to see if any have the same mechanisms as yours so you can get a more detailed video on them.
Tenho um aqui no Brasil e fiz um reparo nele hoje, troquei a luz, estava queimada, troquei os capacitores de 470uf, 220uf que estavam vazados e 1 de 100uf por precaução e pra minha surpresa o auto-falante estava queimado também, e eu achando que o motivo de não ter áudio eram os capacitores secos kkk
Yeah by the 1980s quite a lot of the smaller European companies like Brandt, Nordmende, Telefunken and later Thorn-Ferguson were in the process of all coming under the Thomson umbrella even before they were completely taken over... this definitely has some similarities with mid-1980s Ferguson portables from the UK. The Ferguson ones were brilliant little TVs, very reliable. There is a Japanese connection - Thomson, Thorn and JVC (J2T I think they called themselves) formed a joint venture - JVC designed the VCRs and Thorn/Thomson did the TV's.
Now that you mention it, I think JVC TVs of that era had Hitachi tubes and even a grey coloured LOPT, and maybe even a similar upright power transformer. Maybe there is a connection. JVC VCRs were rebadged as Rank Arena, HMV and GE here on early models, and then almost every VCR for Philips from the mid 90s. HMV also rebadged their televisions after using Fujitsu General for their smaller sets and an Australian designed chassis for a while in the bigger screen sizes.
Great Little TV, and interessting to know, that you know the German Brand Telefunken.. :) one of my first Televisions the Telefunken PalColor 1320 anl later the P540 in Stereo. and many others.
I actually worked for a repair shop that were a Telefunken repair agent in the mid 90s. They also did many other brands. I dont think they sold many here but we did see a few. They had service manuals for quite a few models, and I photocopied the circuits which came in handy for the few Thompson chassis that I saw later on. They also put the brand on some very cheap early Chinese stereos from memory that we repaired a few of under warranty.
Hi Steve, I absolutely love all your vast and extended knowledge of most things electronic. You don't edit out the parts where you need to nut out the problem to make yourself look like a genius, you take us on that journey with you, so we are able to learn along with you! Thank you for being honest and for all the time you put into making these fantastic educational and most enjoyable videos. Cheers, Darren
Glad you enjoy them. I actually want to convey that the repair game is mostly about working on unknown equipment you have never seen before, and the process used to repair it with no prior experience or service information, rather than just a how to fix this particular fault. Learning to diagnose is what I want to teach. Its why I get calls like last week to look at the pressure pump in the local community hall. We could have just got the municipal council to get it looked at, but that would have taken days or more, and we have people hiring it daily to run a small school. So I turn up and look at an Onga pump with pressure bladder on top which I have never worked on. I quickly determine the electrics are good, but the pressure switch doesnt operate when a water tap is opened. I then have to work out what part does what, and come to realise the water inlet to the switch is probably blocked up. As I unscrew the metal over the diaphram, the pressure is released and the switch operates confirming it must be the case. It was some rust and other mineral build up in a tiny inlet tube that I cleared with a screwdriver and bit of fencing wire, and it was fixed within half an hour. It was ability to diagnose things that got the job done, even though it was not an electronics problem at all. Shame I didnt think to film it.
What adaptor are you using at the back?
It has a standard PAL antenna socket. There is a 300-75 ohm balun attached to the built in antennas.
@16:54 I had a problem with discs making a clicking and whirring noise when loading up on a Marantz player, not playing at all and also not showing the TOC but displaying a 'SubQ' error. I found a solution which was to remove the laser assembly platform and then the rubber mounts, screws and springs underneath. I stretched the springs slightly by using my fingernails and put them back with the rubbers and screws etc (making sure beforehand I had made a note of which of them went where - important). Happily I could then play cds which spun up with no clicking, found the TOC with no problem and played perfectly. Thanks for these three very helpful videos on CD repair - brilliant info.
The Best electronic shop i ever visited was a dick smith in the early eighties.,i loved all the funway into electronics books and kits.

Have you got any photos of the AM stereo monitor receiver? I could be interested in that as we are playing around with AM Stereo across the ditch in NZ.

@@StevesElectronicRepairShop Thanks Steve, I must have missed that when I went looking through your previous videos. Do you still have the unit and would you be interested in parting with it?
@@sw6188 Its still where I put it after doing that video. I am certainly not against it going back into service since its obsolete here and only going to end up being used for parts. My email is under the About tab on this channel if you want to get in contact
I had a green one I was 12. Wish your father and I still had one. It would magically transport us back in time and make us 12 years old again. 😂
The cabinet space at the bottom was designed for an optional cassette deck that slid out on a wooden shelf. When I saw the platter mat I had to laugh - just about every one I see, no matter what turntable it's on is upside down. The ribs normally go on the down side. These circuit boards with the printed-on tracks and components are starting to break down. I've seen more than a few where the tracks and vias have gone high or open.
I have never seen one with a tape deck. You are right about the turntable mats. Its been so long since I dealt with them that I dont even notice any more.
A good mod for that would be to put a clear LED in place of the filament bulb... with a series resistor of course. 1 to 3k would probably be good if its a high intensity LED
I like messing around with making loop antennas on mediumwave. Those era radios often used the loopstick on their shortwave band so with some initiative you can make your loop switchable so it also inductive couples to the radio on those frequencies as well
Great score and easy fix! Way too much goes into landfill! I love your videos Steve! Cheers, Darren.
Got a few rotary 801 and 802's in different colours here, got them all to work on Telstra NBN. The audio quality is still more pleasant on the old phones compared the modern "corded desktop" phones that Telstra sell today.
VOIP and even mobile phones are low quality compared to what we used to get on the old dial landline phones. Better lines and speakers in the phones back then.
Really enjoyed this. Same kind of stuff I am attracted to for repair. Nice job on the diagnostics. Catch a funnel web spider for me...
The T200 was my fav of the series.. Crap Membrane, but they looked so futuristic at the time... I've still got one and it's plugged in and working.. It's set for decadic dial, so the # and * keys are disabled. It's also got the worst ringer, but I still enjoy listening to it screech!
I also have one of these radios, I have changed all the capacitors and recalibrated it, it works great!
This is a model that uses fake transistors to enhance the count, a fairly common practice back then. when radios were assessed by the transistor count, the more the better. Some were just placed in the PCB with all leads shorted together, ohers used the Base Collector junctions as diodes.
Steve, if using a momentary switch as a trigger, will a second press of the switch stop the timer and disconnect the relay? That is the function I am looking for. TIA!
I dont think so with these modules. A second momentary switch that disconnects the power would likely reset them though.
I have been trying to find some of those power plugs, or at least find out what the specification is called! The service manuals usually show US/Japanese style sockets for switched or unswitched power or, but the early 80s Australian models have these sockets and standard Australian plugs! Also, DSL stands for Dynamic Super Loudness.
I dont think I have ever seen the connectors listed for sale anywhere, and dont think any of the service manuals say what they are called. Plenty of Aussie sold equipment had the two pin US 110v style sockets so not sure why some used a different sort.
I love the era of portable radios that came with leather cases. They were well protected for outdoor use. Beaches, picnics etc or just listening to the ballgame with a beer on the back deck. I have a couple of modern radios I would love to have leather covers for.
Nice radio
Excellent videos
on this model the common reason the tape does not operate is a faulty/dirty selector switch on the top panel.
I know its been a while, but are you somehow able to point me in the direction of the motor speed adjustment screw for the cassette deck, if it has one? My player is recording and playing super slow and it could be the old belts but i was told they were fine
Its usually a motor fault of some sort if the speed is a long way out. At 9:34 its the large black dot on the back of the motor located around 1-2 oclock. You poke a small flat blade screwdriver through the black covering and rotate
@@StevesElectronicRepairShop thank you for replying! I actually didn't see this comment until just now. I eventually figured that out by pulling the whole mech out and looking around, that was the only possibility of changing anything so I tuned it by ear comparing it to a digital file playing on my phone in the other ear. I'll know this for the future which is great, and maybe someone else who is lost will find this useful. Really cool to see an uncommon piece of 90's tech on a RUclips video, that I also happen to have inherited from my parents.
Update. Never in your life will you find 40 yo foams that look like new!. I have Joni Mitchell's Court and Spark on, these sound amazingly "right". a bit forward as noted below woofer needs a bypass cap. Really well balanced, bass is good for a bedroom system. They are sitting on top of Nova9's.They play way down in the 20's. The 10's are perfect for watching TV/movies if you want to hear the dialog. Yes real veneer, Matsushita = Panasonic. Drop in a modern soft dome, Jensen or Twidec poly caps and always when swapping out electrolytics add 2 ohms to tweeter, poly's have lower internal resistance. Madisound has a great tutorial. RS always had top notch cabinets, be careful sanding the veneer is paper thin.
I replaced the tweeters in my Realistic Mach Two speakers with some Ebay dome tweeters and it made a big difference. Their cabinets are nice and heavy and feel tight. No cheapo light duty chipboard. Its the quality stuff and plenty of glue.
Eu tive um M322. Vendi.
I remember those dimmers from my electrical wholesale days. Back in the mid 80’s, took one home to try. Don’t think Carlton was around to long. Never was a fan of HPM, fairly crap, Clipsal was way more popular.
I found Clipsal and HPM to be about equal. I preferred the look of HPM. The cover plates on their Excel range are rubbish though because they go yellow in the sun.
good video, i just brought a national NV-G16A in black, aparently doesnt display any video, could just be dirty heads hopefully
That's not the original back panel no holes for the 4 caps and no din socket for the 30 v ac to power the pre-amplifier
