Dead slim, now red light

Having a mare day today, doing a slim and after doing several now I just solder it all before reading the nand, so I go read the nand and get "can not continue" to cut it short, after checking and rechecking all connections, I decide to desolder all the top connections leaving just the lower one's(used post qsb for the first time), and tried to start the xbox and got just, beep beep, no lights, fan nothing, so I think it must be the post qsb, now these don't come with any fixing tape, and with only needing 2 solder points I used some of my double-sided tape, now I'm a bit annoyed by this time and running late, so I think I'll lift the board and touch the solder points to release them, but this damn tape is strong and it went with a twang and took the 2 solder points with it.
I checked the qsb and found it to be ok, no sign of any bridging, so I still don't know the fault as everything looks ok(apart from the damage I did removing the qsb), I managed to put some solder in the points, and tried to start again, still the same beep beep no lights.
I searched for similar problems and found that some people damaged the resister near the nand, so I check the resistance and bam, it's in the 100's, all the others are 33, so I took one from an old phat board with the same reading, soldered it in(not straight and moved another) now all readings are around 33 ohms.
I start the xbox and I have lights, only it turnes red after a few seconds, the dvd open's and closes, the fan spins slowly, but no output and the red light.
So to sum up, the original fault was the resister(I've never had this before), but why the red light now? I've not done any repaires on slims so know nothing about them, it's possible the post_out1 and cpu_rst points could be at fault, or could the resister have done more damage?
I don't think the post_out1 will be a problem as it seems to be just a connecting point, but the cpu_rst has a trace to it, I put some solder in but not found how to check it, could these be the problem, or anything else?

Thanks.

Yes checked in circuit, R3B15 from the stby_clk solder point to the resister point nearest the hana, R3B17 same points but from the first resister solder point.

looks like the points stated by martin look wrong. to be honest its not an easy fix unless you know what your doing. i had same problem and sent it to martin as there is a very good chance he can fix it without any problems, i suggest you do the same. i would seriously suggest sending him a pm

Working:smile:
I double checked R3B15 and 17, although they're not straight the ends were soldered and resistance was correct, so I checked cpu_rst again and although it had continuity to r4d4 I wasn't sure of the contact to the track, so I tinned a similar pad and part of the track on the phat board, removed it and soldered it to CPU_RST
and we have power.
So your first thought was correct Martin, just me thinking the solder was contacting the track ok.

So now do I glitch it:confused: risking the CPU_RST pad when I solder to it again, or cut my losses now it's working, it's now mine by the way:redface:

Also what other points can I use for CPU_RST and POST_OUT1, if I don't want to risk them, can R4D4 be used for CPU_RST.

Thanks.

All glitched and working fine:D

At least i've learnt about the resister going now, never knew about that, and had a bit of practise at changing little pads:)

Now should I kamikaze it or not:rolleyes2:

Thanks.

i jumpered from trace under xclamp to the top cpurst point, then back down, looped it, and brought it up to the CR. a mess lol but it works
