Title: Nme 1.2 Solder Problems
Post by: mike99 on August 12, 2007, 11:58:00 AM
i had my NME all working fine, then by accident i pulled off the 5V solder pad (IMG:style_emoticons/default/sad.gif)

(IMG:http://www.team-underdog.com/pixnme/nme_samsung1_2v5.jpg)

i removed some of the black crap round the solder pad i broke off and managed to solder across the piece i broke off, but the drive is acting weird. it will open and close and it recognised, but it makes no attempt to read any disc put in it, even with the NME disconnected.

the point which i have soldered from the diagram is from the 5V line of the SST chip, to the capacitor. Though i think this is wrong. there is a tiny little pad beside the solder pad which i broke off which is not connected to the capacitor. From the diagram you can see this point and the capacitor are not connected.

But from looking closely at another samsung drive PCB i have, the solder point i broke off doesnt appear to lead anywhere? i cant see any connection on the bottom or around the point on the top of the PCB.


maybe i can just extract the drive key from this drive and flash the other samsung drive i have with it?

any help would be greatly appreciated.

just checked the connections on the spare board i have and the +5V solder point is connected to the capacitor and resistor beside it. i have soldered my board as it is and double checked all connections with a multimeter. i have also tried other cables and a different laser but neither seem to make the disc spin.

any suggestions?

just tested connecting the chip again. When the chip is not connected the 360 starts up ok but doesnt play anything, if i connect the chip to the bottom of the 5V capacitor then i get a e65 error?

i now get e64 errors all the time. i soldered from the SST chip top third leg along from the right (i melted away the black stuff and traced the connection back) to the bottom of the capacitor at the broken off point and it now does nothing. it loads the xbox 360 logo at the start then goes to E64 screen.

looks like its for the shit heap.

First off, make sure no capacitors are ruined. Also, check that you didn't pull up any of the SST chip pins, make sure they are still connected to the board.  From what I see it seems that the 5v point may be connected to that big trace.  Look closely, it is on one of the traces, and also looks to be connected to the one right under it.  I dont think there is a way to test, but who knows, it might fix it you never know.

i checked the 5V point and it is not supposed to be connected to the big trace or the trace below, only the capacitor. i did take off the capacitor by accident but put it back again, pretty sure it is connected on both sides. but it didnt work anyway even before i knocked off this capacitor. all the pins of the SST chip should be fine because i only took the black stuff off the top of the pins and nowhere near the bottom.

oh forgot to ask do you know the value of the c404 capacitor and is there an alternate 5V point i can use on the dvd board?

i have now taken off the capacitor completely and have order another off ebay, the value is 100nF. the 0R resistor looks undamaged and so does the one next to it. just need to wait for the capacitor to come then solder it back in place, then soldering the bottom of it to the third pin of SST should fix the problem. fingers crossed!

Hopefully it will work, remember you could always just scrape a little bit of the paint off the top of the trace where the 5v point was, that way you wont have to remove epoxy or solder to the SST chip.

ok, i soldered in the new capacitor and tried it and at first it didnt work. i then soldered a wire from the bottom of the capacitor to the top of the second resistor.

I turn on the xbox and everything works perfectly, except the laser which i know is broken anyway. So i take out the laser cable and replace it with another and turn the xbox back on again. I then got the E65 error again  (IMG:style_emoticons/default/grr.gif)

So i took out what i had replaced and put back the old laser cable. still geting E65.

here is a diagram of what i have done:

(IMG:http://img502.imageshack.us/img502/5855/e65dt8.jpg)

the dotted lines and GND from the capacitor are connections which were there to start.
There is definately 5V AC getting to pin 3 of the SST through the second resistor, and there is a resistance of 130 ohms across this resistor.

The solid lines are wires which i have soldered.

I dont see what i have done here because it is exactly the same as when it worked.

Anyone got any suggestions?

just tested another drive and the voltages i got on mine make no sense (AC was 10V and DC was 5V), so i must have buggered the resistors somehow. gonna get replacements and if that doesn't work then looks like this is for the bin.

that's why people with no experience shouldn't mod. I;m afraid you don't know anything about soldering and basic electronics. You can't just pretend you knew how the circuit works. You don't own the schmatics. You're wasting your time. Stop wasting your time. Send it off to a pro next time. I made that error once with a 360. But it was the network cutoff point.  I couldnn't get the OS to get past the POST screeen for NIC card check thus causing service message E76. I had to rebuild the trace. But what you've done is fatal. I don't think you have the equipment to solder the caps and resistors back on. If you use regular solderi iron it slides all over place. Once end heats up and then the other end. You need like $400-$500 equipment. Solder tweezers. SOrry man. I've also knocked off capacitors. You screwed it!

i have loads of experience with this. i have already soldered the smd capacitor in place and am just waiting for my resistors to arrive. i used to chip ps2's for a bit of extra cash at uni, i certainly know my basic electronics as i'm doing a bloody degree in it. its not hard to work out the schematics if you have the track layout.....

Way to be a jerk.  Your also wrong too, you absolutely don't need $400-$500 equipment, you just probably aren't skilled enough to know that.  I have repaired a few 360 DVD drives (not to mention various computer hardware also) with just my simple 15watt and 30watt soldering irons from Radio Shack.  Its also about the tips you use; there are various soldering iron tips that are made for different jobs, such as needle type tips made for small capacitors and such.  With that, and steady hands, you can do pretty much anything.

Dears,

Please Help! I have removed VCC solder by accident and now i don't now what should i do.
There is no copper anymore to solder so i am not able to make VCC connection.
Here is the picture! As i am not really experienced please explain in detail what shoul i do. I have my friend and i will ask him to do it accordingly (i will not touch it anymore)

Again, please help!

exactly what i did mate, but looks like you could salvage it pretty well. scrape some of the green stuff off the track to the left of the point you pulled off until copper is showing. then solder a wire from here to the bottom of the first component (C404) to the right of the point you removed. This should fix it by replacing the link between them that you removed.

i wasnt able to do this because i wasnt sure what was joined to what at first so i made a hash of my board. but looks like it should be easy for you to salvage yours.

Do what he said above.  Just solder a small wire from the left over bit of trace where that gaping hole is that you burned to the end of the capacitor.  I would recommend replacing the capacitor (either buy one or carefully remove from an old board).  See, problem is, the inside of a capacitor is usually a layer of metal, paper, then metal.  From the looks of it, you could have easily burned it up.

Thx Sir,

At least i have my xbox 360 back.
But i am only able play my demos in harddrive now.(also other dashboard functions are well)

I have soldered 4 wires within Samsung and also 1 for eject button.(this is Xeno-360)

When press on eject (for 5 seconds), it is just starting the console in the beginning and really opening the tray just after 2-3 seconds. Even for my original game it is giving a kind of "Put this disk in an Xbox 360 console".

What should be the problem do you have any idea?

But again already thanks a lot for the first support!

But i am only able play my demos in harddrive now when the chip is activated.(also other dashboard functions are well)

I have soldered 4 wires on Samsung MS28 board and also 1 for eject button.(this is Xeno-360 but actually in their diagram there are 7 points to solder but i followed the guideline in this website)

When I press on eject it is immediately starting the console and when keep pushing it is just opening the tray. And after all, it is just giving a kind of "To play this disk put it in an Xbox 360 console" for both back-up and original games. (i didn't try my bakc-ups in another console so far so i'm not sure if the media is problematic - it is EMTEC DVD+R DL media code:RICOHJPN-D01-67)

But when i open it with normal power button everything is just perfect (w/o modchip) all the demos in harddrive and original DVDs are running perfectly but of course not back-ups.

I think install should be correct as it is working perfectly when i open it with power button. Am i wrong? is there something i am missing?
And final question, is there any application i can download and write on a media just to test my install as Wii has a kind of application as far as i know:

Sorry it became already long but i would like to get sure if my install is correct. Actually i would appreciate if you can give me a link which is explaining testing methods of the install with some pictures or diagrams.(not install diagram itself)


But again already thanks a lot for the first support!

Try an alternate ground point. (IMG:http://img404.imageshack.us/img404/1648/nmejpgqk5.jpg)

I have tried this alternative GND point but the result is same. When chip is not activated it is working perfectly but when it is activated (i understand it from the original games as they are not working -giving put this disk in an xbox-) back-ups are giving same message 'put this disk ....'

I have checked all my back-ups image sizes and they all 7.705.657.344 bytes. My DVD writer is LG GSA-4163 FW 1.06-latest one- and the media is RICOHJPN-D01-67(EMTEC branded but i hade to use mediacodeedit and dvd_identifier in order to burn this media because even latest firmware was not including this media code) and IMGBurn has successfully burned the media at the end. Actually i know it is different topic (i mean the media) but firstly i am trying to get sure if it is not hardware issue anymore.

I thought it should give 'unplayable disk' or should not see the disk in the tray if the media was wrong. Don't you think same? Can it still give this 'put this disk...' message even with bad media?

I have already ordered Verbatim's but they will arrive at weekend i will let you know the result.

In case needed, this is the information shown by ImgBurn for burned disk.
Current Profile:DVD+R DL but booktype DVD-ROM. Does it make sense for Xeno-360 full chip (Actel labeled square shaped one).
And if i have to change the booktype to DVD+R DL how can i do? because actually i had selected Normal in booktype section for my burner but it seems it is still DVD-ROM.

Hmm...I really dont know what to say at this point.  Are you absolutely sure the install was done correctly and properly?  Maybe try not using any extra points (only the required ones) and insulating them too with either tape or glue (to prevent shorts).  Check every point for continuity (with a multimeter).

yey! got mine fixed. i did it by replacing the 0ohm and 22Kohm resistors then soldering from the bottom of the capacitor to pin 3 of the SST chip. All works perfectly now. though i had to buy 5000 resistors to get the 2 i need (IMG:style_emoticons/default/wink.gif) thanks for all the help.

I have done it, thanks! It was due to media. I received my Verbatim DVD+R DL 2.4Xs and works perfectly.
For the others: don't waste your money with cheap medias.
