    I was finishing up the norway and used some soldering braid to clean up some excess solder with out realizing I killed one rectange and completely removed and lost the other. I know that the whole ps3 isnt dead and that there are no shorts. What should I do im considering getting a cheap parts ps3 and use that for the rectangle. also what did I disconnect? If anyone could help me that would be great. I would be sad that my first gen ps3 was dead. I think its possible to fix but I may be wrong. I did power it up and it gets somewhat far and then shuts off and blinks red. Help would be much appreciated.
    Also I am somewhat skilled (6-10) soldering wise (I know it doesn't seem like it when I killed 2 rectangles) so I know that I could do it especially with my magnifying lamp. And would I be a dipshit if I just instead bridge the pads where the rectangle was?

    Thanks in advance

    The whited out is what I killed.

    Hi,
    Those SMD parts were not there because Sony had too many of them in stock, so it's good you asked first . Most likely they are resistors (all of the same vaule), but i'm not sure. Take out your multimeter and test the part you still have. If it reads something like 10kOhms, it's most likely your lucky day.
    I don't know this specific board, I'm just deducing from what electronic knowledge i have, so no guarantee. Would be better if someone who owns (or knows) the whole board could acknowledge this. To me, it's a bit suspicious that the two topmost conducting paths are not separatet with ground paths (for shielding) like the others below.

    Thank you for replying I just checked them and they are all the same ~33Ohms. I think Ill go out and buy like a 20-30 dollar ps3 and desolder it from that one and use it. but if anyone else has some advice and knows this motherboard that would be great as well.
    but thank you Ezez

    Can't you just buy some surface mount resistors from an on-line store? Probably run you a couple of dollars...

    ok I found a couple resistors on an old 97 dell laptop would I be foolish to use those they are not the exact same smd but they are within .2 ohms of the original I tested it with a multimeter?

    Take it easy, buy ANY resistor of 33 you could put inside. No matter the size or form.
    Dont solder directly on the board, use some cables.
    Even 2 of them to reach the value.

    The other one is just a bridge.

    33 Ohms means most likely that these are some resistors for transient surpression (ESD protection). Bridging the missing one would most likely work, but would be bad style, and, given that the cost of a replacement resistor is just a few cents (plus shipping) not wise.
    I would consider a resistor between 22 and 47 Ohms safe, the outline is irrelevant, as Player1 pointed out. If you can solder the resistor from the dell donator laptop direct on board if you can connect it to the pads.

    Dont solder directly on the board, use some cables.
    Why that? With a pair of simple tweezers replacing a 1005-outlined SMD resistor is a piece of cake. Just remove the old solder from the pads, apply some fresh (preferable with lead, it's easier to work with), place the resistor with the tweezers, solder one end, solder the second, solder the first again, done.

    The other one is just a bridge.
    I'm curious why Sony did this. There is no conducting path between the two pads (as it is with C3116 i.e.), so this SMD-Bridge is kind of senseless, a piece of conducting path would have done the job as well.
