Wait... Maybe you mean just the laser unit. Noooo. I found a complete unit. Mechanical and optical.

I said I can replace an optical unit in 5 minutes because it's freaking easy. Unscrew 4 screws, unplug the ribbon cables, change the unit, plug the new ribbon cables in, then put everything back in place (ground places as well) and you are good to go... Skills are needed to replace single small parts, not an entire optical unit. Did I miss anything???

Nonono! You ain't negative at all (at least to me) but straightforward and I love people like you coz I'm the same. Haha. To answer to your "perplexity" about my behavior... I just have got confused in the process (too many variables). About the reseat and reset... I thought that everytime i reseat the ribbon cable, the machines would reset, like with the jumper... I know, i got messy... The only reason why I prefer to replace it, rather than "revive" it it's cost/time related. The optical unit would cost me 38€ and 5 minutes of work. Trying to fix the original unit, only God knows how long it would take and how much it would cost me... If someone could help me out how to repair everything in short time and for less than 38€ I would be more than glad... But except you (and I thank you for that) nobody seems interested to give a hand. Sad reality...

I maybe have found a deal/solution. Is it possible to replace a je780 optical unit into a je770?

Picky: I thought you meant that the MDM7 "doesn't like" to be replaced. My bad. Haha. Reseat, sorry again. I thought it was simply a typo. I didn't mean that I wanna abandon the deck but that I'm not willing to spend much. I'll try over and over to fix it but with a limited budget. At last but not least I read the whole topic (thanks for the link). But in short, some people just revived their machines (like the je980 owner) randomly. Deasembled, then reassembled and for whatever reason it started to work. Others failed and at last from mid-page 3 it has become too technical for my knowledges about electronics... Haaa, I'm so depressed right now (about the machine, of course. Haha).

Thanks for your reply as well. Why "picky"? It's not a replacement, the MDM7 never left it's "home deck"... I had the same stand-by problem, but it's easy to fix: just "force" a little bit the arm (on my left) to eject, unplug the AC and then the machine turns on again. How do you reset the ribbons? I just tried with the jumper. And how can I get in the service mode? Just to check, at least the hours it was in use. Anyway, I guess after the op cleaning and and ribbons reset... I'm done... As I wrote on my first post here in Italy, people are incompetent about minidisc decks and I'm not willing to spend more than 50€ after I have spent a total of 63€ in: belts (I bought 2) 24€, 1L of isopropyl alcohol 16€ (couldn't find a smaller size) and the rest to the "technician" for checking the machine and the price quotation. I guess I'm at a dead end...

Done 3 times. Nothing changed. What a hell is this story? Seriously the MDM-7 are sxit?

Thanks. But geez, so hard to remove...

Wow, that was a great explanation. Thank you so much. But how the heck... How can deteriorate everything so quickly and altogether (belt and the lens)??? One week before was perfectly functional and then this absurd escalation, like the deck decided to commit suicide... It wasn't like the fisiological degradation explained by you. It skipped altogether in 3 steps: eject error> only toc reading> no reading at all... At this point I don't know if it makes sense to attempt any cleaning. :-( I'm a bit shocked to be honest. To find a donor deck in Italy is like looking for gold... :-( Moreover, 1 whole week learning "how to do", waiting for the belt from the UK and then this "lens surprise". :-(

Thanks a lot for the prompt reply. I'm assuming that is the spindle coz before before the repair the laser read the toc, normally... It recognized the disc, but then it didn't read the tracks. Actually it's a tricky situation. I can send you a short video before the belt replacement. You can see that the disc was recorded in LP2. Anyways... How can I try to clean the lens safely? I'm scared to death to touch it. V_20200526_171356_DOC0.mp4

I quote reminiz. I'm having the exact problem with a je770 and it's definitely the spindle motor. But have no idea what to do next. I changed the insert/eject belt with a new one by myself, thinking it was the only issue but I was wrong... The laser works "looking" for disk but the spindle is simply dead. Moreover here in Italy, technichans don't even know what minidisc is (it sold a bit only in UK and Germany in Europe) and I was asked 100€ from the "professional" just by opening and looking in it... No way! An advice would be GREATLY APPRECIATED!
