Hi all,
Ok, this is my first post/thread, but not my first job. I've only recently discovered this forum, before that I've done a lot of recaps on older boards, but this one has me stunned.
First, I did a search on this and a lot of other forums to no avail. Seems that no one had Thinkcentres in their workshop, which is cool for IBM, but unfortunately, these babies do fail and they fail big time - I did a full recap and I've still got nothing.
Since I don't have the board with me now (will have in a few hours), I'll just explain the symptoms and what's done and then upload photos when I get the board.
The board is labeled as MS-7024 (so it's a MSI) - socket 478, non-standard format. The board was filled with Nichicons HM (10v, 1000uF), 2 of which were swollen, near the southbridge (ICH5). Also, there were 3 large KZE caps near the ATX connector (25v, 820uF). These all (both Nichicons and KZEs) are replaced with appropriate Panasonic FM (all matching datasheets, of course). Symptoms: the computer fires up and stays on with Power-On LED and IDE LED both lit, fans running at full speed (with working processor, power supply and memory) - no beeps no nothing, just stays that way. It doesn't seem to matter if I pull out the memory and fire it up - still no beeps, same state. Unusual thing is that PATA attached drives are not spinning, nor functioning (appear as if they're not attached to power supply), but if I remove the IDE cables, they're functioning properly (sata drive is functioning properly when attached, though). Southbridge seems to be a bit hot for no apparent reason (does not have a heatsink on). The same thing was happening before I did the recap.
Anyone ever had problem with these or knows what's going on? As I said - I'll post some pictures in a few hours.
