1. make sure none of the traces are shorted to ground (all the area around the traces is ground)
use a multimeter to do this.
2. you need to rebuild the trace that was over 101. you can solder a wire straight across it.
3. you probe 2 probably won't work, but might be able to stab through the board, just try it and see.
4. if the probe can't make a contact through the board and 101 and 122 are gone, u will have to use a 22 ohm resistor
and probe a resistor on the opposite side of the board (usually under the epoxy) w/ it.

I'm using prob 2 where do I have to insert the pins if pad 101 &102 are damaged. My drive is lite-on 93450
Just put the probe into the hole, it doesn't matter if the pad is broken (i've done that and it worked). If it doesn't work, try to clean up the hole with a needle or something like that. |

Thanks a lot Guys I'm really great-full for you efforts in helping me. Dream, I'll try to do the soldering as per the pic. but pin 122 it totally gone so what should be the alternative point, I'm getting of Measure resistance 3,3V to GND 70.4 only. xboxer1234, I've tried this but the jungle flasher and dos-flash don't recognize my drive Here are more clear pictures of my PCB. http://img375.imageshack.us/g/img00018201007172243.jpg/ |

Dream, do you know where I can get the voltage information for the traces? I'm trying to fix the old drive which had problems with ejecting the tray. (i bought an multimeter so i can test it now)

Thank you all for trying to help me in fixing my lite-on drive
I've tried almost all the different ways described under this subject but non of them worked !
may be it's needed to provide one master way as step by step tutorial to repair damaged PCB

There is no master way. Additionally most people who royally f their boards do not have the skills to fix them either. |

I''m good at soldering but what I mean is there should be a base line to start with !
