How to repair lite-on pad 101

[heartshacker]

Any expert comment will be helpful. Have done a mistake once. Do not want to do it again.

Guys, i just screwed pad 121, if i put a jump between pad 101 and the pad 121 trail will i be able to save it?
thanks

[iateshaggy]

yep, as long as 101 is in tact.

[flamesdragon]

now 101 is screwed too, damn, what can i do now? if i do this fix i need to put the wire in the back and in the front of the board too?

[iateshaggy]

sorry, time for you to hire a pro,  if you wanna sift through this thread, your fix is in here, but knowing when to toss in the rag will prove to be more cost effective.

[flamesdragon]

plz, i know that this picture is my fix, but i just wanna know if i need to make all the yellow lines or just the ones in front or the back of the board
thanks

[iateshaggy]

show me a picture of what your board or i'm only making guesses at what will fix your board.

Solved! damn, i couldnt believe it! The main problem was the 22 resistor. I used a 15 resistor and worked like a charm.

Btw - Drive Liteon 93450c - Elite Splinter Cell Edition. Well if have patience, read my drama below... lol

Thanx to the people helping via MP!

Hi i´m reading this Thread about 5 hours, i´m almost giving up, can someone please give me a little help?

   I´m not at mod/ flash, i do 93450c all the time at the first try, but today i have a damn match. The damn drive was giving me status 052 all the time in jungle flasher, i tryed everything, from making deeper cuts to soldering, and changed the resistor, used 20 ohm ( 2x 10 ), 22ohm, and nothing the damn status was the same, so, after desoldering and check a milion times,the pin 101 has gone with the trace above ( only inside the cuts ) and i made the 101 fix with the wire on the front of the board.


Drive is working ok, jungle flasher detect the drive ( open circuit), mobo detect the drive(open), with closed circuit the drive don´t detect in JF, but the status is there 052.

After 101 fix, i put everything stock again, looks like this.is this right?




So i dont know how to proceed from now, i don´t have the drive key , it´s a brand new Elite. I saw some pics about doing the extraction via the method showed below.But i have some questions...

1 - What to do with the blue at the "cornering?" do i need to make the soldering on that 2 points? can u show me a real pic so i can copy the wiring?


2 - With the 101 fix at the top of the board, can i dump the firmware via pin 122? do i need to make the soldering exactly on top´s 122 head?


3 - with the 101 fix i have tried to dump via 122, but JF gave me status 80 to 052, what the heck is going on? ( using 22 ohms )


Update:  i made the 122 method to dump the firmware, check ou my pics and see my wiring, is this ok? do i need anything else to make it work? because till now only gimme 052.



Update 2 : Tried the probe atached to resistor method, i made exactly as shown and guess what : 80 or 0x52 - JF fails at intro
 Tried dosflash, the same damn thing 080 to 0x52

I´m going crazy here, must be something missing, because u made another liteon minutes ago with the same resistor ,and worked fine!

Update 3 - I reassembled the drive to stock (fixed the cuts and made the 101 fix on top of the board ) the drive works stock, but is kinda strange, the optic make some strange noise like reading and sometime u have to eject and close to the disc load properly.





I don´t know what to do anymore, please help me. almost 12 hours and nothing.

the way you are attaching the wires is shorting out your board.  you need to only expose the shortest amount of wire possible and it needs to be attached to the trace in the same direction the trace is going, not perpendicular like the letter T.

[flamesdragon]

iateshaggy, i was able to put the drive back to stock because i could recover pin 122, now the drive is working on xbox but he is not reading any games, do you know why? thanks

[iateshaggy]

either you have to take a picture of your board, or i can't help you.

Yeah, i got this fixed, thank you for the observation! running fine now!

btw,i heard there´s a lot of users with noisy drive after reparing the board? Do u know why this happen?

I noticed one thing, when u repair the trace with a damn thin wire, a.k.a. "Hair" lots of problems show up after a few resets and ejects. maybe not voltage enough?

Hi All,

I got reference from other forum. Need you help.

I have liteon 93450C (Model : DG 16D2S-09C/Manufactured date :  Dec 2009).

I think I fired my DVD by upside down power cable (Not sure about it). But I saw smoke just after I plugged power cable. I was following MRA hack. I do not see any fired part in the PCB.

Here r the pictures for both the side

I used XBOX as power source for the DVD. I powered XBOX with DVD plugged in when I had trace cut. As it fired, I do not have key. After the DVD fired I repaired the trace cut and tried to power the DVD. With DVD powered ON, I get 3 flashing red light. Without DVD the XBOX works.

I have gone through the post. My understanding is that first I need to check  following.

Set the multimeter to 2M it should give you 0.100 - 0.105.

I am not expert fixing electric equipment. But one of my friend is expert. So I shall take his help to fix this. First I shall ask him to check the above. If any other steps are there let me know.

Just a question -- Do I need to provide power the PCB when I test the above.

If I need to provide power for the PCB, I guess following r the voltage details I need to provide ..

DVD power cable pin3 3,3V eject --> 0V closed.

I have checked the resistance using above method .It shows 68ohm. For r709 it is 131ohms and for r710 98.7 ohms. DO u think my MTchip is ok?

What else I need to check? I think I also need to check following

Impedance between 1.8 V and GND.
Impedance Between 3.3 V and 1.8 V.

If yes how to check that?

[iateshaggy]

either you have to take a picture of your board, or i can't help you.

[flamesdragon]

iateshaggy, i tried to take pictures today of my board but no succes, they are blur.
but i guess the problem isnt on the bottom, is on top, i just found a burned resistor, the one in this image http://yfrog.com/11hiresdj

Can i bypass it, since it is a 0R resistor (R55 on board)?

Thanks

[iateshaggy]

yes, it can be removed and patched w/ solder.  i'm sure you know someone w/ a camera.  things like that burned resistor are the kinda thing i can't know about if u don't give a photo.  any advice i would have given you w/o that knowledge would have been pointless.

[flamesdragon]

this resistor only works like a fuse? wont be a problem to bypass it in matters of protection?
my cam has a terrible macro, so these pics was the best i could do

The resistance 3,3V to gnd is 68ohm. For r709 it is 131ohms and for r710 it is 98.7 ohms. After consulting with some of my friends we decided to bypass r709  and r710. As the resistance  can not be so high. So we short r709  and r710. Do you think it is safe?

Here is the image

Thanks in advance..

[iateshaggy]

i'll be honest, i don't know what shorting those mounting points will do, but they won't fix your problem for sure. all your board looks like it needs is a little less solder on it.  use some wick to clean it up, cost 1.25 at electronics stores.

[flamesdragon]

iate, u said this for me or for him? and i can bypass the resistor because it only works like a fuse? but the circuit wont be unprotected?
thanks
