In this video we're going to be taking a look at a TASCAM DR-701D 6 Track Digital Sound Recorder. I came across it on eBay and looked quite interesting so I bought it! I had no idea what it was or what it was used for at the time, but let's see if we can figure out what's wrong with it and hopefully repair it!
I'm not an expert, but I do enjoy trying to fix things.

I love your videos where you have to make some generic replacement part work for a repair. Hats off to you for your ingenuity on this sort of fix. I was amused by the "Waiting for comments" on the hot glue fix. Hey - it's a damn good fix! If you ever watch Electronics Repair School, Sorin manages to fix broken laptop hinges and all sorts with hot glue. At least you can get hot glue off or re-work the stuff fairly easily later down the line. Keep up the really entertaining videos.

Thanks 👍Sometimes you have to get creative 😂😂 I was fixing my oil boiler last night at 1:30AM as it had stopped working and was just buzzing and tripping the electric. Turned out to be the startup capacitor on the blower motor. I ordered one but it's going to take a few days to get here.. so I had a look around and found one on an old bench grinder.. fitted that.. 2AM working boiler again 😂😂😂😂

Well carrying on from your last Evil Genius video, you have just re proved your Evil Geniusness in using ALL Red wires. Always makes me smile in the films when they get to the "do I cut the Green or the Red" as if there is a intergalactic agreement for which colour wire to use where 🙂I now have a whole new respect for you. Also need to ask, did you wire up my Land Rover Trialer? All the wires on that inside were Red 🙂

Yeah - great work. Not a huge fan of Tascam - had one and ended up getting rid of it in favour of a Sound Devices MixPre 6. It was the precursor - DR-70D 4 track recorder. The DR701D is 6 channels (but only 3 XLRs) timecode IO (the BNC socket on the side) and better pre-amps which is a big upgrade for production but the ergonomics on the Sound Devices and the pre-amps are just much better for production.

Quick tip for anyone who is working on boards like this where there is a danger of shorting stuff out. Cut out some pieces of card roughly the size of the back of each board and tape them to the back of the pcb so if things fall over there is far less chance of shorting out something critical and letting the magic smoke out. For boards with high voltages (CRTs, camera flashes, valves etc), use plastic sheet instead of cardboard to lower the risk of high voltage tracking. Don't just go with.. "It will be fine, what could possibly go wrong?", listen to someone who has blown up enough stuff to know what he is talking about.

Hello, one thought. You actually never showed us if you tried to reflow connections from 28:01. Maybe it was cold joint? It surely was responding to temperature change. Just an idea for next time. 31:07 - I dont see what you see or how you split boards, but one paper or just a normal plastic bag would be much safer isolator between boards I believe :D especially when moving
@BuyitFixit
@BuyitFixit Ай бұрын

@orion310591RS
@orion310591RS Ай бұрын
@@BuyitFixit Im refering to the moment 23:45. You touched with oscilloscope from under, possibly touching solder blob from side. Cold joint is in the middle, middle is where is no connection. 1. If you touched from this upper side you might find trace without signal. 2. Even if you touched all traces with signal from upper side, it doesnt mean its connected well on end under this black glue. Contraction because of freezer spray, makes glass push down toward pcb, then metal contact fulfill its purpose to connect. Solution maybe was, that from this side, 23:45, to heat with soldering iron, trace by trace and let it cooldown. Not from under, under would reflow only under part of contact. If you didnt throw away small LCD, I would suggest to try to reflow it.
@BuyitFixit
@BuyitFixit Ай бұрын
I do see what you mean at 23:45 and that pin does look like it's not quite connected on the top of the PCB. The pin goes to the one of the capacitors used to generate one of the internal voltages (which were present when I tested with the scope). If you look at 23:48 you can see the pin is soldered correctly on the bottom, and the trace it goes to goes to capacitor C488 marked on the back of the board. I've had a similar failure on the FLIR thermal camera I repaired, which also displayed a blank white screen.

Would it be better to use a FPC breakout board with a bare COG module, or maybe just replace the whole controller board with a new one that can talk over SPI/I2C I'd go with the latter, as it allows to change the display type(I generally prefer OLED for these small screen use cases)

I used one of those small blue OLED's on my internet connected Geiger counter I built a few years back. Some of the pixels aren't as bright now and it has a type of "screen burn" which I guess are the OLEDs burning out over time.

@bleeedthebrakes Ай бұрын
@@BuyitFixit That's definitely the most worrying characteristic of OLED screens. However, the recorder seems to have a backlight feature, which should extend the screen life somemore. On the other hand, I realized that the use case for this particular recorder(DSLR companion recording) might need the screen to still display while the backlight is off, so OLED might not be applicable.

😂😂It's hard enough editing especially with sometimes having to use up to 5 cameras. (Thermal, microscope, oscilloscope, overhead, and sometimes another camera if I have to do something outside such as testing or in the workshop), so having to sync audio etc (although I do have to do that with the microscope camera as it doesn't record audio).

@@BuyitFixit There may still be ways of improving your audio without unduly making it harder on yourself. If you have a microphone input available on the camera, you could connect a small mixer with phantom power to make use of any XLR condenser microphone you could think of. (I bought a used Mackie 402 VLZ4 pre-pandemic that has been serving me well. Warning: some budget models will only provide 15 V or so for phantom power, not the full 48 V.) Maybe eBay will turn up a good fixer-upper large-diaphragm condenser? Mic tech has some special areas like gigaohm input biasing on "real" condensers but the circuitry is hardly rocket science by your standards. Should the used market fail you, there's some really decent LDCs you can buy for not much money. Thomann's t.bone SC400 is splendid with high output and low noise but may be a bit too much on the bottom end for your voice, it's not super brilliant up top and may apprecite a bit of EQ. (Also, the shockmount needs some ingenuity before it starts doing its job properly, it's way too stiff as it ships.) The Marantz Pro MPM1000 is also decent if noticeably lower in output and with less proximity effect (both expected from a smaller electret capsule, and considering that its noise level remains very decent). What you may actually want may be an overhead pencil condenser, though smaller diaphragm size means that noise is much more of an issue. The t.bone SC140s are good for the price IMHO but little better than a noisy old LDC from the 2000s (Samson CL8 in this case) in the noise department. The truly good level doesn't really start until you get to something like a RODE NT5 or Line Audio CM4 at 3 times the price or more. If you have a stereo mic input available and your editing software can do things like inverting phase on one track and adding it to another, here's a balanced input on the cheap. Add an inexpensive phantom power adapter to it and you don't even need a mixer. (Note that workmanship on these can be shoddy and inspection may not hurt. Again, it's not high-tech. On a side note, I would not rely on adequate protection and advise against hot-plugging mics while phantom power is on.) Input noise is not likely to be any worse than the Steinberg UR12 audio interface I reverse-engineered the other day, that's got the better part of 3 µV (outside of the range that Julian Krause shows in his EIN measurement graphs...). They basically put in some extra series resistors in the input to form a fixed 6 dB attenuator and ruined noise performance in the process. Just don't buy the cheapest microphone arm you can get, those predictably tend to fail in the same spot sooner or later. In the XLR cable department, you could easily buy some decent mic cable stock and Neutrik connectors and solder some up.
