Great job 👏. Not many people would even try to repair something like this portable DAT machine. I'm always impressed with your patience. You've inspired me yet again.
@27:35 Wise advice.. I schedule routine tape player playback for a few machines I have and small portables with hard to get belts so they don't form memory - some of them I have taken out the belts , will service them and put belt back if I sell them which I intend.
Very interesting video, as usual with you, I guess I will use it in a near future. I've the same machine which seems to work but I experienced a lot of drops and glitches when I play DATs (not just one but many) and 2 of them was even chewed. Do you think it could be related to the tape guides? As you could expect this poor sony was laying on a shelf for 10 years and as you pointed out , it's like vintage cars, inaction is bad 😉
What are the problems I found is that yeah the guides tend to wander on a lot of them. so if you're experiencing High dropouts it could very well be a tape path alignment issue. Because generally and I have been using dat for probably 30 years dropouts are not that big an issue for the most part until the tape gets excessively worn.
@@12voltvids Thanks for you reply, Mr. 12volts. One of these days I'll use your video to open the little beast and check the tape path. I fully uderstand an old badly stored DAT can have problem but well, as I experienced the same with many I suspect there's maybe something bad inside the machine. As all those things work with only few fractions of millimeter of play, the pubic hair of a fly can make the difference. I'll try to find this hair... 😉
just a question do you think that physical media is a thing of the past and the technology to play it on and do you think there will be a revival i heard that cassette are coming back and the decks wii be built in europe from one audio RUclipsr cheers peter in Australia just to say that i was in that era off VHS/cd/records/beta/cassettes / but i have embraced the new technology eg the apple echo system and wats your opinions.
OK so I’m confused they made a DAT player that if you wanted to use batteries you have to open it up and solder a jumper just so you can use the batteries that seems like a lot of work what am I missing?
No there is a switch inside the power Jack that disconnects the batteries when it is plugged in. That switch failed so when it was unplugged the batteries were not reconnected. I put the jumper in so that the batteries would operate, however now he has to remove batteries when he's using it on power otherwise it will supply power to the batteries and charge them which could cause the batteries to burst or leak. The owner is fully aware that if he is using it on external power that he must remove the batteries but it gives him the option that batteries can now be used. The solution would be to change the Jack however that is a special Jack and the parts have not been available for the last 30 years.
Hello 12 Volt, I been having trouble seeking out someone to repair the same device like this but the TCD-D7. I player gets an error , 11 Error. It doesn't allow it to open. Any chance you offer a service to repair it?
Portable DAT's and video camcorders are a nightmare to service. Its quite easy to destroy something when disassemble them, delicate flexible contacts and other things that break apart.
@@12voltvids You might have to put a limit on some of your repairs. Yes i know i'm takling crap as i used to repair into the early morning from the day before. I was a bit too determined, what a daft sod i was.
They can be yes. I have a few others I am fighting now. They had been attempted repair by the owners and I am struggling with them. When they havent had someone else into it I have a pretty good chance of repair.
I've been following this channel for my Sony TCD-D7 Walkman which is not opening and showing an error 02. Thus far, I have learned the following: 1. Downloading a copy of the Sony TCD-D7 Walkman service manual is very helpful 2. For all disassembly so far, the screws have been Philips M1.4x2 or M1.4x2.5 3. Group screws for each part (e.g. a circuit board) in separate containers so that you can easily reverse the order for assembly 4. Use Isopropanol Alcohol for cleaning metal tracks 5. Use MolyKote PAO grease for lubrication of metal and plastic parts 6. Be extremely precise and careful when unsoldering battery wires not to affect any surrounding connections It may transpire, as in one of 12voltvids other videos, that the problem with my TCD-D7 is more fundamental than gummed-up mechanics, in which case I will have to purchase a second-hand DAT player (maybe Tascam) to transfer my tapes.
I have the exact player (D7) and same error code! I was hoping to get an answer here.. the service manual describes this error 02 as “not in position” so something is out of position with the mech and possibly not allowing the Open signal to pass to the door lock.
Yes there were, but that was some 30 years ago. Major brands like Kenwood, Alpine, Mitsubishi, Pioneer etc. did offer such car decks albeit mostly for JDM only. Some vehicles like the Celsior (ie. JDM variant of first-gen Lexus LS400) were also available with the DAT deck option; the result was an in-dash integrated cassette/DAT audio head unit with CD changer control.
@@alanarmstrong2323 You mean those for car use? Speaking of MD, did you ever recall a single DIN unit with BOTH CD and MD slots? Still can't figure out how this could be done, even though it was likely one single laser pickup was used for both (but not together)......
DAT was one of the higher-end audio formats back in the 90s but hardware were very expensive and also difficult to manage/maintain/service, with the D7/8 having very high failure rates AFAIK. But I disagree that the D3 was the smallest DAT Walkman. The main unit might look small, but then after adding the external battery pack it looks much longer. I'll have to say the D100 (and the PCM-M1) are the smallest in the entire portable DAT lineup......
@@12voltvids That, I agree. It's hard to eyeball the D7/8's actual size until one gets his/her hands on one for tries. And it's indeed a bit bulky. The D3 by contrast appears s bit more packed in design, but that green EL LCD backlight was addictive......
@@vampyrelycan99 the El panel on mine is kaput. That was the coolest feature. Mine has been fixed a few times and works great. I also have 2 teac and a tascam portable but they are not exactly pocket size like the Sony.
@@12voltvids I understand the EL backlighting strength diminishes upon very long use.

I’m just wondering if you have serviced the D100 which is smaller and only uses 2 AA batteries 🔋 as I think you said the D3 was the smallest
I have one with the same issue i think...thanks for sharing this, i will try to make mine work again!

Sell them quick. Someone with more money than brains will buy them.
@12voltvids, can you tell me what the brand and product of oil you use at 18:33 is? Thanks.
Thanks I need to run my D8 and TCD-D100 which I think is the smallest DAT Walkman or maybe the player only WMD-DT1

Either a charge circuit switch or to stop dual voltage and damage the unit

Tape is dead, some are just hanging on. Vinyl should be dead too, but some like the inferrior sound.

Hey 12voltvids I’m getting “02 Error” on my D7 and looks like the open slider doesn’t open the door. Any advice?
Probably the usual suspects, gummed up mechanism.
