how to fix pal v5 ps2 mobo with datatrack burnt off?
how to fix pal v5 ps2 mobo with datatrack burnt off? –
i've removed my previous thread as it was regarding a bad magic 3 install and i'm really only concerned with a fix not a mod at the moment. here's the important stuff.
i've aquired a pal v5 ps2 with a bodged magic3 install. chip has been removed and ps2 has been confirmed to work. (managed a temporary bridge to the broken track)
problem: solder point 'i' (below cd/dvd controller) on bottom of mobo has been burned off the board and there is less than 1mm of track left visable before it goes under the cd/dvd controller ic.
possible solution: take 30 or 34 awg from the via on bottom of board (or the corresponding leg on the ic on top of board) and connect to an assumed via/component etc on the top of the mobo.
following advice offered by ps2guy, i've put a multimeter to the tiny trace that is still visable on the bottom of the board, but it is very difficult to maintain connection to this track whilst probing the top of the board.
can anyone check the continuity that comes from the large ic on top of the board (just above the 's' point) to another point that should be left of the 'w' solder point.
relayer is really helpful if ic ant help you replyer will

thanks for your effort guys.
i think my description of where the track has gone wasn't the best so i've defaced an install pic to show where the problem is. if you look at the blue line from the i point, this is where the break occurs.
i was able to check the continuity from the bottom of the board to the to the large ic nect to SCEx point and believe it or not, the i point is in the same area if not the same leg.
so i know i can jump a wire from here, but where does it go to? i think it should be in the same area of the i solder point but on the opposite side of the board.
as i was having such a problem maintaining a good contact with the multimeter prob near the i point, i tried referencing a pal v7 mobo.
although the board design is different, there is enough similarity between the cd/dvd controller etc that i should be able to make some progress (hopefully).
i spent the best part of 2 hours running the mulitmeter probes accross the board (top and bottom) starting near the cd/dvd controller ic but on the opposite side of the board.
i was hoping to touch a via that would be linked to the ic leg that lead to point 'i'.
so far no joy. i haven't been able to pin point a 0 ohms continuity (but am i looking for 0 ohms or just a rating below a specific value?).
just tell me one thing before i do a repair doc for you does the track you ripped wonder all the way under the cd.dvd controller.EnTiTy

if you can still solder to the track you ripped do this for a quick fix.
or connect straight from the I point on the diagram posted by relayer to the via shown on my pictue to repair the problem.
hi entity, thanks for taking time to look at this.
i already traced the track back from the burnt 'i' point to the via you show and used a multimeter to confirm the correct leg on the ic on the opposite side of this via with the hope that i could do what you suggest.
there's too much track burned between the 'i' point and the ic. less than a mm is left and i don't think that it will take the heat of my 15w solder iron.
this was why i was wondering if there was an alternate point i could use to connect the via you've shown to the track going under the ic.
