In the white outlined part under the GPU (under the metal cross) there are 4 rows of 4 of these things each. (there are more of these things but they are not in the rows).
Can anybody tell me what these things are (likely to be capacitors), and what value/type number etc. these are ?
Due to the crappy soldering of MS one of these things came loose (error 0102), I was able to resolder it (dont ask me how) and it worked again for about a week.
The second time I tried to solder it back but it got lost... now I want to try soldering a new one in place, but I need to know what to buy.
So please if anyone can help me...
tia,

I also made this mistake puttong the Xclamp back on I knock one of these weak resistor off and lost it (IMG:style_emoticons/default/uhh.gif)
If someone fixed this please say what to resistor get and what to do I am lost

gpu looked good after heatgun was done, put it back together and got buzzing sound and error 0003 . Barely found any information of value except this post
QUOTE(G0t M4xx 21 @ Jan 28 2007, 10:35 PM) 
error 0003 is a problem with the regulators for the CPU/GPU, so either the regulators died, or one of those chips fried and died, and is shorted out.
So it's definitely a motherboard issue.
So upon looking at this post with the provided image and ppl mentioning scraping off thier caps/resistors i decided to double check, lo and behold I think I found the problem! i didnt scrape though, I melted.
I am missing the circled capacitor, the one next to it ..to the left, is half off kind of warped looking, also the other one with the arrow the big one looks liek its melted, I stayed in the area wat too long with a 1000f heatgun.
hmm IPB image ? well ehre is another link
All of my hope was lost till now, this board was about to go for sale as parts, but if i could fix it even by bypass the resistor with a chance of frying the chip in the future i dont mind...shoudl I risk it by bridging the two points together
Or does someone knwo what these are..I may have to repalce more than the ones circled since who knows what internal damage coudl have bee ndone to the rest at excessive heat?

anyway checked the ohm reading at 200 ..getting 0.4 ohms to 0.5ohms on those little 4rows where I'm missing the resistor..but getting same reading from the points..same reading with flashing lights..dont think its sendign any voltages to the area..or i'm not testing on proper setting.
Post by: RDC on February 20, 2007, 07:20:00 AM
Every part under the GPU, or the rest of the board for that matter, that is a Small Brown Rectangle is a CAPACITOR, not a Resistor. Resistors are either going to be Black or Blue. You can NOT "bridge" where a Capacitor was with solder, ever. Physically, yes you can, but you wont like the reality of it at all and it should never be done. In the best of cases you'll be making a short and the thing just wont work, worst case you make a short and it takes something else out with it, so don't do it.
Some Capacitors can be left out of circuit or have the values slightly changed and there isn't much of a difference in the way the circuit will work, but some are extremely critical and used for timing or passing signals and MUST be of a certain value, as well as be replaced by the exact same value to retain the proper function of said circuit. Since there isn't much technical data on the 360 and what value each part is and what they doexactly, they SHOULD be replaced with the same exact value component.
As has been stated in this thread before... The only way of knowing the exact value of it would be to have the parts list of the 360, ask someone that designed it or remove one from a known working board and measure it with the correct insturment. If none of those things happen you'll have to rob one from some other dead board and use it.

here is what i found thus far
Common "TC" include:
X5R = ±15% change over -55°C~+85°C Standard Tolerance: K = ±10%
X7R = ±15% change over -55°C~+125°C Standard Tolerance: K = ±10%
(IMG:http://www.niccomp.com/Images/tctables.gif)
"Substitution Rule: A component with a more stable (better) temperature coefficient (TC) can replace a less temperature stable TC component.
i.e...an X7R ceramic can replace X5R, Z5U or Y5V ceramic part
i.e...an NPO ceramic can replace a X5R, X7R or Z5U or Y5V ceramic " (http://www.niccomp.com/ceramtc.html-ssi)
Convertion guide maybe use something else..these seem to be certain temp resistant

The 1206, 0805, 0603 and 0402 are just the physical sizes of them and have nothing to do with what value they may be.

Need some help or advice here. I started getting error 0102 about a week ago on my 360. I did some research and tried the arctic silver 5 and also the hot gun fix but got very little results. The 360 starts up after being heated and works for about 15 minutes before freezing and resulting in error 0102 after being restarting.
I then carefully removed the clamps again and decided to check for loose solder points and to my surprise I found a broken component. I'm not sure if the component would be called a capacitor or resistor but it looked broken. The location is on the underside of the MOBO directly under the GPU (please refer to attached Pic).
I really don't think I could have broke it off as I was really careful while removing the clamps. Now I'm pretty confident of my soldering skills, is there anyway I can replace/repair this? Please help.
QUOTE(G0t M4xx 21 @ Oct 20 2006, 08:57 PM)
that capacitor really isn't necessary, if you look, it is simple in parallel with ALL those other capacitors around it, it simply acts as a filter on the main power supply for the GPU. Like BCfosheezy said, having that component missing does not actually break any circuits. However, it would be advisable to replace it.
Searched xbox-scene forums .. picture above is exactly how mine looks like except not as shiny..the other cap is partly off to the left..next to the one thats off. I dunno if that would be the cause of error 0003 and buzzing sound or what..since new evidence seems to suggest it should still at least work but might be more problems with my board than are visible to the eye.
Post by: RDC on February 20, 2007, 10:55:00 AM
Exactly, most Caps, not all but most, that have one side attached to Ground are more than likely filter Caps. These should be in place, especially when dealing with an IC or chip like the GPU, but odds are it will run fine without the thing on there. I'd be looking more on the top of the board, if you had enough heat on the bottom to get those parts loose then who knows what else has gone flying off the board in a lot more sensitive area. The GPU has Caps on it and if any of those were removed you could bank on it not working correctly.
Post by: devilspy on February 20, 2007, 11:08:00 AM
I would think if we can contact ATI or have them provide data sheet for r500 / r520 gpu core we would be onto something here.
Post by: Solmod on February 20, 2007, 05:38:00 PM
It does not work I think it stops it working, to those that say it should work, no..3 red light for me every time
Rest of motherboard is fine..
I thank for research but we have no solution I hope an expert can help
Post by: devilspy on February 21, 2007, 02:44:00 AM
Would you happen to know the exact values?
In theory my box shoot boot but doesn't, error 0003, would two of those line filters missing = that?
Post by: mygameswirelesscom on February 21, 2007, 07:16:00 AM
but no luck so ...
i have bab mobo so ...
yes it is from mobo !!
i need to pull it out ..
it looks you could solder but ones
you look at the pices it is very very small
hey yours r on the way so good luck !
p.s. if you get the goods you could come to my ebay
give me a good freeback !
you may need to pay 1.99 or 2.99 most !!
THAT IS ONEY IF YOU WANT !!
pm me whan you get yours
Post by: devilspy on February 21, 2007, 07:40:00 AM
Thank you!
Hope this works, I could bid and not pay..and still give you good feedback. but those ebay fees are killer
Post by: Solmod on February 21, 2007, 06:10:00 PM
Please tell us how you fix this if so, does you just put it back on it works? Anyway good luck.

the parts indicated in red appear to be missing on my board. (R4R8 and R4T1)
where they should be, it looks exactly like the area indicated in green (R5R3 blue with no sign of black things...)
Since these are black, are they resistors instead of capacitors?
Should I worry about them being gone?
Is it a good idea to bridge the connections?
If I need to have those parts, which replacement parts should I get?
if this in not the source of my 0022 error, I am going to try the betty crocker method...
since the naming convention on the labels is RxRx or RxTx I am pretty sure that those are resistors...
