MZ-G750 Unboxing & Repair

[@royphillips4758]

I had to dig out my version of this MiniDisc and believe it or not it's still works today complete with remote control with radio working paid about £20 for that about 4 years ago

[@CBitsTech]

£20 was good. Especially good in today's market with the remote too. Very nice.

Hi There, I always look forward to your videos, I suffer with anxiety and these videos really help me relax, keep up the great work

[@CBitsTech]

Thanks. I glad to hear that my videos help you relax. They are a bit boring :) I hope you can get over the anxiety problem. If you're not taking them already, I hear there are some prescription medications that might help.

[@hgrunt100]

I think these videos are great for anxiety too, I know what you mean!

[@CBitsTech]

@@hgrunt100 I suspect my videos are popular as a remedy for insomnia too.

[@hgrunt100]

@@CBitsTech It would seem so.

[@IAmKAZMO]

I have a multitudle of MDs ... I recently purchased this model... It feels and sounds like a high-end device.... The metal is premium. I probably wouldn't have bought 2 or 3 if I had came across this one. Love 'em ❤️

[@CBitsTech]

That's a coincidence, you saying that. No spoilers, but this player is in my next video that goes live on Saturday.

@CBitsTech I just subscribed ...🫡🤫

[@CBitsTech]

@@IAmKAZMO Awesome, thanks! And welcome to the channel.

[@highfidelity1989]

Nice MD unit 😊 Regarding the noise I assume it is the sled motor. I had the similar issue with one of my Sony MDs. Unscrewed the back cover and flipped over the mainboard (only removed 2 ribbon cables). After that I removed one plastic gear so that I could pull out the sled motor rotor. I cleaned the rotor and lubed it with some lithium grease. It was much quieter afterwards.

[@hgrunt100]

Ahhhh yes, the late night eBay session, Im afraid i've done some damage myself recently off of one of those. But MD fiscal damage is always worth it, just tell yourself its an investment! Loved this video. I enjoy the long-form repair videos you do.

[@CBitsTech]

Thanks again. God, the fiscal damage has been huge over the last three years, and buying this stuff is getting more expensive. I have plans though to help ease the fiscal pain of any future late night ebay sessions.

[@hgrunt100]

@@CBitsTech If that plan happens to involve posting some of your units for sale on eBay, do let me know! I'd be happy to arrange the shipping too, since I live in the US.

[@CBitsTech]

@@hgrunt100 Thanks. Yes, the plan does involve selling a few bits on eBay. I was scared off the Global Shipping Program for some reason, but I can't remember why. I'll look into it again to see if I can offer international shipping. I'll announce sales in my videos, maybe short videos.

I have this model. Bought it new in 2001. Did not use it for years. There is some corrosion in the battery compartment. Not too much, though. Cleaned it up. But, I can only get it working if I open it up with the case off, and run it with a power adapter. The FM remote does not work either. It also has the same noise as yours. Would love it working again normally.

[@CBitsTech]

Try cleaning the contacts on the remote unit to get that working. If it's not working with the battery, I would suspect there's more corrosion on the inside of the unit. Sorry, it's really difficult to guess if I don't have sight of it.

Great for 'hiking' carry along for music and switching to broadcast, before smartphone streaming came along.

[@CBitsTech]

@@leonarddaneman810 Yes. Sounds perfect for that.

[@Bobby_Snoof]

I have almost the same player (the MZ-R700 doesn't have the FM/AM) , and it makes just as much noise as yours, even after completely disassembling, cleaning and lubricating it...

[@CBitsTech]

Thanks. That's good to know, it seems like they're just noisy players rather than there's something wrong with them.

[@ianz9916]

@@CBitsTech I have two MZ-R700 machines and one is noisy and the discs don't read. The other one isn't noisy and works fine. There was definitely something wrong for it to make that noise. Probably needs more lubricant which you'd have to disassemble the machine to apply.

[@bodeorungbemi5741]

Hi just found your video. Got one of these that I bought new many years ago and enjoyed tremendously. The radio and remote works fine but the player doesn’t work anymore perhaps due to neglect. When i put in a MD it whirs silently then the display shows “NO DISC”. I have tried so many times but same result. Would really like to get this working again as it has a lot of sentimental value for me. Any suggestions?

[@CBitsTech]

Hi, sounds like the disc detection switch might need some contact cleaner or IPA. I don't think I've ever fixed a disk detection switch, but I heard from someone else that it's a common fault. Another thing to try is to put in a disc and press play, and as it starts to spin, hit the side of the player near the control buttons into your hand. What you're trying to do there is free up the laser shed. Sometimes they get stuck. There's a video of me lubricating one here kzbin.info/www/bejne/ZpfCZqaFl9SLqKs

I didn't need to go further than your description of promising yourself not to bid on anything further...and then doing so anyway to relate. 😂 When you opened your box with unknown contents you convinced me. You are an honest likeable guy who seems to have at least one mutual interest with me. Looking forward to your vid... lol...I actually stopped watching during the moments of recognition that I just shared!) And hopefully more mutual interests in musical devices to still share. Thank you! Ummm ... Probably obvious but I'm sadly ignorant of KZbin. Life happens, and it happened to me, that took me away from advances in Audio. If we are able, we get to expand a bit on the life we wanted, after such times. I love music. I enjoy learning about the amazing technologies that exist/existed to enjoy really great sound! I have rarely commented before. I wanted you to know your sharing online mattered to me. Sincerely, AcoustiNaut at yahoo 🖖😊 ☯️

[@paulroach2538]

Noisy 'just like the RM 70 you did a video on '. Keep up the good work I have one with the tuner remote and listen to the cricket on long wave .

[@CBitsTech]

Thanks! Yeah, but I think this one is noisier than the RM70. I'm guessing that the tuner is in the remote itself. Do you know? Does it show the frequency on the player, or just the remote?

[@paulroach2538]

[@paulleblanc2474]

Hi My Names Paul. We spoke before about getting the sonic stage working. I hope you can recall me. Anyway I have a MZ-G750 as well. Its broken as well. when I slide over the record button and try to record off my computer , the timer starts blinking i don't know if that is good or bad. Then I press play to record, and nothing. The play button doesn't click like it used to either. The disc icon is flashes as well. I tried pressing pause to make sure its not on pause and then It says sorry. i DONT KNOW, CAN YOU HELP ME PLEASE?

[@paulleblanc2474]

Also Im trying to record with a digital optical cable. On both the mz-g750 and the mz-n707 but these were in really good condition and they both are now saying sorry. is it even possible to record by toslink or that a myth?

[@CBitsTech]

Yes, sounds like your player is waiting for a digital signal via TOSlink, but it's not getting one. Sounds like the thing sending the signal isn't sending a signal that the recorder can understand, or the player is trying to send something with DRM. If the recorder is flashing a counter which isn't going up then it's on record-sync waiting for a compatible signal from the player. The recorder recognises that it's getting a digital signal and is waiting for the player to play something it understands. It sounds like the player is sending an incompatible signal. Perhaps it's DRM, or maybe the wrong frequency.

[@paulleblanc1567]

Hey Cbits tech I talked to you earlier around December on another platform I was trying to Uninstaller the driver and get sonic stage to work you remember? Well today I'm deciding to go with buying an older laptop that already has win 7 on it. Will win 7 work with sonic stage cds? Hopefully I don't have.to buy an older Lap like xp and win7 will do the trick. Thank you 4all.

[@CBitsTech]

Hi Paul. SonicStage CDs won't work with 64 bit Windows 7, but may work with 32 bit Windows 7. The following link describes a user-modified version of SonicStage that I used years ago to get it to work. It was difficult to get it to work, I think. Since then, I think the link to the downloadable version of SonicStage that did work on Windows 7 has been removed. Have a read here and let me know how you get on forums.sonyinsider.com/files/file/95-sonicstage-43-ultimate-edition/page/3/

[@paulleblanc1567]

Hey C bits tech I recently won a dell laptop 2100 series its from 2007 I believe its a windows xp Now That I know must work with sonic stage right? If I could find a copy of so ic stage hard copy CD off eBay then I would know what to do there. Let me know thanks

@@paulleblanc1567 Hi Paul. I'm mobile at the moment so can't test the download on a PC, but it looks like it will work on XP on this (Sony) download site, although the download function has been removed I think. It will be available somewhere on the net, just use caution downloading stuff. Or get it from eBay, as you say. www.sony.net/Products/SonicStage/

@@CBitsTech hey yeah I guess your mobile atm maybe you can test it later. Another question is : there's several sonic stage versions from 1.2 to 4.3 (i think that's the latest one which I want) but do you know which one would go best with my windows xp dell LAptop from 2100?

@@paulleblanc1567 What do you want me to test?? I can't install it on an XP machine just like that lol. If you check the website I linked to earlier, that has compatibility. I would choose the latest version of SS that you can get that is compatible. Sorry, still mobile 😔

@@CBitsTech hi, have you ever come across a sharp md-mt888h unit I now have two one is perfect just the usual battery leak crap but now works perfect, the second unit is very temperamental starts up try’s to work but just shuts down , on the odd occasion it has played the disk no problem, can’t get my head around it, any advice would be appreciated . Regards Lenny

[@CBitsTech]

@@lennymaunton3183 Hi Lenny. I only ever owned one Sharp and it didn't work. I think Sharps suffer more than most with failed laser diodes. I would guess that this is the case with your non-working one too, especially if the laser sled moves freely without too much noise. However. I think that model is a recorder, though. With recorders, the laser is used to heat up the disc surface to a very high temperature to allow the magnetic record head to record new data. I'm guessing that those lasers must work at a higher power than a player that doesn't record, so maybe they don't fail as often. I'm just 'thinking out loud' here. I'd lubricate the rails and worm gear first, check there's no fluff on the laser lens, and if that didn't work I'd take it to bits and see if there's anything obvious wrong with the circuitboard; could be battery corrosion on the board, maybe.
