Hi

I have a N710 and it has been working perfectly untill now. When i try to download songs onto the MD, according to SS2 it is on the minidisk and the process completes successfully (although its VERY quick i.e 5-15 secs for a whole song) and the MD does the TOC EDIT. However the song doesnt play. The disk spins but the timer doesnt move and nothing plays mad.gif Even more when i turn the MD off then back on the disk is Blank!!! However MD's that i have already created work fine so it cant be a laser problem can it..........?

If bits dont make sense plz tel me and il try 2 clear it up. help will be needed soon as im going away and want some music to listn 2!!

Well there is an thermal head and an optical head in the Minidisc recorder.

The thermal head heats the surface of the disk and then the laser changes the Ones and zeros. One isn't doing it's job and I belive it is usually blamed on the Thermal mechanism.

Well, the head could be dirty, it could be bend away or the cable to the recording head could be broken.

In case of dirt, cleaning it with an alcohol soaked q-tip could solve the problem, head bend away or broken cable needs a trained technician to repair it. The head is exactly over the lens in the lid.

In the lid?? On the lid of the MD there is nothing but the connections for LCD screen and nothing above the lens....... :wacky: What does it look like because there is one thing which hangs over the lens on top and is very small and white.....is that it? Thank you v much for help.

Well there is an thermal head and an optical head in the Minidisc recorder.

There is a laser and a magnetic write head. The laser increases power above that used for reading to heat the substrate to its Curie temperature, and the magnetic write head alters the domains that represent zeros and ones.

To me, it sounds like a problem with the magnetic write head. Some units have both the magnetic write head and the laser/optical pick-up block assembly attached to the same carriage; so the magnetic head and the laser assembly move even during playback, putting stress on the ribbon cable connecting the unit's mainboard to the magnetic head.

I suggest getting the unit serviced.

hmm....that's right not software but hardware... hey according to your symptoms it's the magnetic head or the other components in connection to it that got issues... now it's pretty easy to replace :grin: if you could get the part BUT...that's a challenge what i'd suggest is get a cheap old unit from Ebay and do some operations :wink: if you're interested in experimenting i'll be glad to look for a post i did on this some time ago

ok first of all you should have a very small philips screw driver (i don't remember the exact size but by the size of the screw head you can tell),a saudering gun, a black piece of cloth to work on (the screws are shiny if lost you'll easily see them on the cloth), a cool environment (chances are your hands are gonna sweat), and a good photographic memory :cool: ok

now bear in mind i don't actually have a N710 but the structure of the units from 2000 up are either exact or very very much the same anywho...

now to disassemble the unit:

1. unfasten all the screws around the back of the unit (i.e not the screws around the lid with the display and controls etc)

2. with the lid still shut hold the unit in your hand with the data port, optical input, mic input and headphones/remote input facing you with your left hand holding only the lid and your right hand holding only the back .. now gently try pulling your fingers apart(not your thumbs) as to open the unit from the opposite end facing away from you NOTE* do not be aggressive and take it all apart because there's a data cable connecting the controls to the main board (if that's broken you're in deep shit) now you should have the frame seperated from the back cover right?

3. you can now unfasten the screws from around the lid (at this point the lid is suppose to be ejected so you you'll see the skeleton of the unit which is all silver blah blah..) gently pivot the lid from the top (holding the unit with your right hand on the frame and your left hand holding the lid open the lid like you'd open a book (i.e. spreading the top not the bottom)

now you should have the lid apart from the silver frame

4 you'll see a date cable linking the controls in the lid to the main board at the base of that cable where it's connected to the board there's a socket which you can just unlock by using your finger nail and pulling the brown* latch downwards releasing the cable..

5. now to ensure that it's the date cable linking the magnetic head to the unit that's broken you could hold down on hard metal you'll c with 2 screws in it NOTE* do not apply pressure to the flimsy strip of metal that the date cable runs on, now you shift this left and right by applying a lil pressure and you'll feel this click effect as the mechanism run on the threading of the uhh( :smile: i forgot what you call it newho) shift the entire mechanism to your right till it stops (you'll notice the entire lens system move along with the head etc) now pay close attention to the cable..it's supposed to be smooth all i.e if you notice a sharp bend in it then it's just damaged if you see it broke then it's broken.

6 replacing it, you gotta unscrew the flimsy strip of metal fastened by 2 screws and some glue and remove it...

by now you should have have that piece of metal in your hand while the rest of the cable remain saudered to the board , now you could either head the sauder or tear the cable from the board (by tearing it you're left with the solid sauder so when replacing it you could just heat the sauder and connect the ends of the cable...

uhh now i might have missed some details :grin: but nothing major i'm sure.. now to replace that whole magnetic head thingy ..when you buy and old md unit and you're taking it out you should not tear the cable from the board but rather heat the sauder so it just slips out and then reconnect it to the old board and screw it back.. but this time you gotta make sure it's flush with the lens or else you'll have recording errors when recording..

uhh as for the units to use i'd suggest any unit manufactured by sony since 2001 i.e from MZR 700 just to be on the safe side now if all this is done and there's nothing wrong with your cable or magnetic head then it's an optical pick up problem and i'll have to tell you how that goes..

remember the procedures follow them step by step and remember... you're doing this at your very own risk :grin: i will not accept any responsibility for your actions.. with all that said...

take care :cool:
