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.

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.

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?
@12voltvids

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.

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 😉
@12voltvids

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... 😉

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......

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.
