Ok here's the story. I was installing a Matrix Infinity in my V7 PS2. Upon soldering the SCEX point, I got a little bit of solder on the neighboring resistor. I thought it was just a little piece of solder, not completely attatched to it, so I tried scratching it off with a small precision screwdriver (BAD IDEA!). Upon doing so, the tiny resistor broke off the board!
I desparately tried soldering it back on the board, but it kept coming off, or was completely off-center. The last time it came off, the resistor broke in half!
So what, am I doomed now?! Any suggestions?!? This is the resistor that I broke off as a result of stupidity(circled in GREEN):
http://www3.telus.net/lamielf/ps2.jpg
I couldn't get a reading out of the broken resistor, using a meter. I'm afraid that I might've melted the pads in which the resistor sits on, or the black resistor that the SCEX wire sits on.
Can anybody PLEASE help me?!? This whole thing has been really worrying me and stressing me out.
My only idea is to replace the resistor, so if ANYONE out there has a V7 PS2, can you PLEASE check that resistor with a meter and tell me the reading in ohms, so i'll be able to replace it?
I would be EXTREMELY greatful for any help at all! Any ideas and or suggestions would be greatly appreciated.
Thanks!!

xshredx,
use a digital multimeter and check the resistance, starting on the lowest resistance setting, working your way up (It might me good to use alligator clips, so that the testing electrodes hold themselves on there).
Go to your nearest electronics store and find the resistor's matching, or very very very very close to value in ?s (ohms).
Hope your PS2 isn't screwed.

ahhh man that sucks!
oh well, i guess we all learn from our mistakes eh? next time i'll be extra careful and be less of a clumsy idiot. yeah if i find one i'll be sure to drop you a pm.
if you don't mind sharing, why is it that you need one too? did you have a problem similar to mine?

oh sorry, didn't see epepper9's post.
yeah i did exactly that, but i couldn't get a reading.. i must have been holding it wrong, i'll try it again. do you know where can i get resistors that size?

Surely someone must have a V7 apart who could check the resistance value of a good resistor for him. i would love to help you with that but mines a V9.

What you might try (when you get a new resistor) is to get a pin (as in a needle...not a writing device) and get a dot of superglue on it and place the resistor where it's supposed to go with tweezers...obviously be very careful about placing it. You shouldn't put so much glue that you can't get it off the board. Just enough so that it should stick well enough to solder it back...be sure to use plenty of flux to let the solder flow easily when you resolder the resistor back on.
In the future, it's prolly better to just slowly work excess solder off with your iron =)...or just leave a little bit of extra solder on it unless it's getting in your way.
I'd help you out with identifying the resistor, but I only have a V4 and a V9 =/.

Alright, I forgot to mention that resistors are not only measured in ohms, but also in there tolerance, and wattage. If you get one with not enough wattage handling, it will get hotter, be more resistant, get even hotter, be even more resistant.................... Then die, or desolder itself.
I suggest getting one with the lowest tolerance, say 1%, this is how acurate it is to its ohms rating, also get a pack of 5 or something, because they should be about 6 cents each, unless wirewounds.
eg
a 5% half watts(usually brown body), 1% 1 watt (blue or green body) look like this:
Wirewounds available in 5 or 10 watt:

Thank you for all of everyone's help so far!!
Yup, I learned all about tolerance and whatnot in electronics class. So where can I get this kind of small resistor? I beleive they're called surface mount resistors? If I can't find one I guess i'll just take one from an old cpu motherboard.
If the resistor is not soldered on correctly or if anything else is broken(i.e. a component melted), will I be able to tell right away?

SHit!!!, I forgot they would be SMD (surface mounted) components, oh weak....
Anyway, I am in AUstralia, so I would go to jaycar.com.au, but otherwise, find a local shop, go to their online cataglog and find the part, OR use froogle.com
as for finding the value, I dont know what else you can do, post a photo, of where it came from and get someone with a v7 to have a look for you.
Whoops, I should've had a closer look at your link originally, sorry.

ahaha the resistor is like broken in half so im afraid i can't do that.

haha no worries i didn't really talk about that in detail.
i hope i didn't damage the pad.....

Heres a real good idea.. Ok mother boards are expensive you dont need 1. go to a pawn shop they sell ps2's for like 40 bucks man. If that dosnt work find a crack head the always have cheap ps2's and you might even be able to get a ps2 and a tv to play it on for 50 bucks.

You don't necessarily have to use a surface mount type resister as a replacement. You can use a standard type, snip the lead ends to an appropriate length and solder the tips to the contact points on the motherboard.

yeah i was thinking about doing that
but i don't know where to get 1/4 or 1/2 watt resistors with low tolerance (i could get some from school but tomorrow is the last day before winter vacation and i still have no idea what the value of the resistor is.
so if i can't find smds then yeah thats a good idea, i'm definately gonna do that, thanks a lot.

From the picture it looks like a capacitor not a resistor. If indeed iti s a capacitor then it probably is used for decoupling and you have nothing much to worry about. The typical values are 100nF.
There are various size in SMD caps like 0803,1216 etc so you need to be sure. THe Digital multimeter will not shoe anything if this is a cap. I have a V9 PS2. I will open it and see if there is similar circuit inside.
did you power up hte board and check, a removed resistor will normally not cause a catasthropic failure anyways.

you cant measure the capacitance in-circuit. I suggest you try a standard smd value of 100nF it wont cause any harm at all.
Capacitance meter are not so common, you need to remove capacitor and measure it externally, not easy, plus risk of damage again for any one who tries. These are normally fixed in place by a little adhesive during manufacture.
just try teh the standard it should work if everything else is okay.

oh good thinking,
I have a capacitance meter, which clips into a digital multimeter, Id lend it to youl, but uno, your probably thousands of kilometers away from me.
You can test normal capacitors on resistance setting in a NORMAL multimeter, but only to tell if they are a capacitor, or maybe not, but its weird, you have to short the leads together to get rid of the charge and stuff.
I dont know what a capacitor would do on a main board (well all capicitors store a charge, obviously and there are many types, hopefully only 1 smd type), but on a power supply it would be for decoupling to stop distortion, ie. voltage drastically dropping up and down, but they use electrolytics not SMDs.
If you have long leads on a capacitor tester, and the circuit is OFF you can test them while there in, because nothing is short circuiting or discharging, I would have to think, but I have not done this with a PS2, so I may be wrong with that, cant hurt to try.

Think I have broken something too! Just installed the Duo 2SE chip and am getting disc read errors displayed on the start up screen with any PS2game or DVD I insert in it. I have a version 9 PS2 and a clicking sound coming from the lazer, at startup it also goes straight to system configuration and displays no data and disk read error Can anyone please provide some advice?

I have my V7 apart and I just measured the ill fated resistor. Its 2.3 Meg Ohms. You could connect one end of a new resistor to the SCEX point and the other to the end of the trace where there is a solder connection point. I checked the continuity and they are connected.

df65: so you're saying that if i just use a 100nF, it won't put out too much/too little voltage that could damage the ps2? do you know about any canadian websites that sell electronic components like smd capacitors? (i live in Vancouver, BC Canada)
and about checking your V9 ps2 for a similar circuit, this is the V9 diagram from the official Matrix Infinity website:
http://www.infinitymod.com/matrix/files/chips/Matrix%20Infinity/V09/USA-V9.JPG
I believe that the capacitor that we are reffering to is the component that the SCEX is pointing to (in the V7 diagram it is pointing to the resistor right beside it).
epepper9: do you mean normal, as in an analog multimeter? i have one but it has the same features as my digital one.
Scotz: Sounds like you have the ol' DRE problem. I've been successful in fixing my friend's scph30001 PS2's disc read errors by adjusting the angle between the laser and the disc. The same thing happened before i fixed it, it kept making clicking noises, which is the lens moving up and down, trying to read the data. Before you go about adjusting the angle, LIGHTLY dab the lens with a Q-Tip soaked in rubbing alcohol and let it dry.
The best guide i've ever seen so far:
http://arstechnica.com/articles/paedia/hardware/ps2.ars
Since you have a V9, locations of certain components may vary. good luck and be careful.
cool_jct: did you measure the thing circled in green? sorry, it was my mistake, but we confirmed that the resistor indicated was actually a capacitor.
