My only comment is: this is a servo mechanism. As such it will display strange behaviours when it stops working (ie cannot self-correct by repositioning and maximising the signal for a track). Right, Kevin?

Understand completely. I don't think I would be confident to try it either. I've carried out some maintenance on decks (MiniDisc and cassette), and am happy enough soldering wiring in guitars, but portable MiniDisc recorders would require a whole different level of precision/skill that I just don't think I have.

Hello to all, Recently i got my hands on this minidisc deck. I bought it as non working which indeed wasnt,mechanism was dry and out of sync,lubed it clean it and reads ok. Recording is another story of it, doesnt record since the recording head was messed up by the metal frame inside and was badly bent and cut. My issue -apart from this- is that sometimes when i insert a disc,or changing tracks,or middle of the song (same spot) the laser looses track and mysic stops,or if its on toc reading stays there forever. Disc cant eject and player enters a zombie state which wakes up after 20-30 minutes,regardless of if i unplug cable switch of etc. No service menu is possible too. Is this something familiar to anyone? Actions i had were increasing laser output through Service menu,quite a few steps 6-7 and errors are less. But occur.

Yes, I know that but I don't feel remotely confident enough to do the work involved...my son has volunteered to have a go (he's done things like replacing the battery in my cellphone) but I don't think he realises how fiddly the process is going to be with a Minidisc.

@zzzuppp - have you seen that you can get replacement OLED screens for these now?

Sounds as if its in very bad shape. The usual problem with MZ-RH1s is the OLEDs going (I have two MZ-RH1s and both of them have lost both OLEDs) but all those other problems you mention haven't visited themselves on my units. What a shame for you.

Much as I'd love an RH-1, I fear I completely lack the skills required to resurrect it. Very generous offer though @Syrius! Hope it finds a good home.

This is not a delayed April Fool's joke. I can't bear to have this mostly-dead RH1 with me, as I cannot use it, so I'd rather hand it over to someone who may want to take it apart for parts, or what have you. I've kept it safely tucked away in a drawer, humidity and smoke-free for years, so it hasn't been mishandled, but it has started to develop more and more failures over time on its own. You're getting it AS-IS, so know what you're getting into before you decide grab this unit: One of the OLED panels doesn't light up anymore. Unit will NOT enter PC-MD mode when connected to a PC. Not sure how or why. The computer will not detect it, but power flows through. The jog lever doesn't respond when moved up or down, or will do something else other than moving the track forward or backwards. (Opening the edit menu, for example) Same when used with the remote (not included): It will either not respond, or activate an entirely different command. Unit will read the disc TOC, and play it if you can get it to "listen" to your pressing of the play button. Makes no difference if it's formatted as HI-MD or legacy. It will try to charge the battery (not included), but I haven't been able to confirm if it will do it to completion as my battery is old and doesn't retain the charge. Unsure if the recording capability still works, due to how "deaf" the unit has become over the years. I was able to record a couple discs before storing it away, however. Please give this unit a decent send-off, dissection or burial, at your discretion. All you will have to pay is the shipping and fair and reasonable handling fees. I will only take Paypal. I will ship within the USA. Canada and Europe, PM first to discuss shipping based on your location. Thank you.

I'm sure it's a function of how many bots are attacking us. Speaking for myself, I know there were huge runs about 1 month ago (around 25/2) but that might be different for someone else such as our hoster which is somewhere in the USA.

No, it's not an April fool, we appear to be back 🙂 We seemed to run out of bandwidth especially early in March?

The standard RM-MC38EL should work. Maybe if you dream about it you can wake up with an idea of what to do. I'm stumped. However the middle bit looks like the NH900's.

Well, I was able to remove the lid from my MZ-DH 710 and then remove the circuit board from the lid. The part is the same as shown in the RH 900 service manual:, I have a non-functioning RH 900 to experiment on. Unfortunately, the exploded diagram showing the 'jog dial' and '5 way control key' is a tease. The entire switch control is a single sealed unit and soldered solidly to the circuit board. I imagine that if one ever went in for repair, the entire circuit board would be replaced. Bummer! , especially so because there is no remote for this mode and it doesn't have even have enough heft to be a paper weight. Thanks for the assistance. Maybe I'll send it to some Sony repair facility and see if they react in any way.

Limp means it's not electrical, i think. Take a look at page 50 of the NH900 service manual. The others will surely all be similar.

Thank you, Yes, a service manual would be helpful ; a pretty exhaustive search yielded nothing. I was very surprised when the button suddenly went limp. I did have the impression that it was a well designed and tested version; a little larger that than on other models. // OK, I just took a look at the NH 600, 700, 800, and 900 service manuals and I don't see anything about how the jog dial and 5 way button are assembled or a view it's component parts. I'll have to remove the lid carefully and see if anything obvious is revealed. I recall taking the lid off an NH 900 because the menu button won't bring up the menu when pushed and held, except on a rare a occasion, and I couldn't see anything to fix. That one is probably not a mechanical issue but something with the circuitry and beyond my skills.

I can't offer help on this model, but i recall something similar with an NH700. You'll have to take it apart. Inside the lid the switch board is probably secured with a couple of screws. We're hampered here by not having an exploded diagram from the service manual, but you might benefit from the fact that these designs kindof evolved... yours being a later one than said NH700. Not much use but don't panic yet. Kind regards Stephen

The other thing that changed recently is the effectiveness of Chromecast (and I am sure the many clones). I am away from home this week, and for the first time I am able to blast my videos from home (not copied, but via the internet) directly on to the TV there. So if you have a phone that will get the content you need, maybe this is enough. Once again, this is not a property of the TV, but the fact that you can reliably plug in a device which catches your casts from portable device(s).

Hello, I'm hoping I can get some advice or assistance to repair the 'jog' button on my Hi-MD MZ-DH 710. The button which adjusts volume, previous/ next and 'enter' has come loose. It is in place but flops around and does not connect with the functions. Has anybody fixed one of these multi function jog buttons. Several models have them. Any help is welcome and appreciated. Thank you.

This is the model number: Sony 65" Class - X850G Series - 4K UHD LED LCD TV

Thanks. I was thinking hardware to be honest because you would think a total factory reset would fix the issue?

Very kind of you but I think 6 years later this guy is probably long gone. He only ever came to the site in 2019.

Sure. But if you are having trouble with software that browses the internet on that particular date it seems not unreasonable to ascribe to a common cause. I'm sure there's nothing wrong with your hardware. I have Sony TVs from the last 20 years and both sport access to things "out there" (eg music sites that are long gone) and no longer do any of those extra things.

Hi @tsfrance. What model of Bravia do you have? Might be worth asking over on AVForums - Sony TV Forum (UK based) or AVS Forum (US based) as if this is a wider issue I am sure others would have flagged it.

I am a bit confused thought as what Firefox on a computer would have to do with a Sony Bravia tv?

There's a kerfuffle of sorts relating to Firefox's root certificate expiring on 14th March. https://www.theregister.com/2025/03/13/mozilla_certificate_update/ Was your problem beginning exactly then? It's not clear to me that Sony ever used anything from Mozilla - but what do I know? Seems a bit of a coincidence..... If it were me, I would stop relying on anything baked into your TV (and updates thereto) and get a real computer (for example a Raspberry Pi if you cannot stand working with Windoze) to drive the TV screen

This is a very odd situation. Our Bravia is about 3 years old and now issues. Nice picture and sound. A few days ago when my wife pulled up the page with all of our apps on the tv and picked an app, nothing would load. It shows the app page but if you pick any app, say Netflix, it just boots you out to the main screen. Same with settings. You can get into settings but most of the time when you picked a setting you are kicked out to the main screen. Sometimes she found a way to make settings work. So after searching the internet for help it was always the same 5 things. Soft Rest. Unplug TV. Software Update. Restart Internet and the final one was factory reset. We put off the factory reset as long as we could but finally gave in and what a mistake that was. Now we can't do anything in settings at all because it boots us out. So we installed Netflix and we were able to do that but when you try and sign in it will boot you out to the main screen before you get the password entered. What a mess now. For the time being I had a Firestick in the drawer so we are using that with no issues now. My wife wont be ok with it though because now we are using 3 remotes and I should not have to use Firestick on this TV anyway. So am I going to have to buy a new tv that has a great picture and works great except for pulling up apps and setting??? I hope not but if the factory reset did not fix it, what will? We are very very frustrated to say the least and would appreciate any help. Thanks very much. Tom
