...and as soon as my desoldering pump made contact with the power supply board I knew how wrong I had been about the caps probably not having leaked. A familiar smell permeated the air...
Anyway, after recapping the power supply I got a chime; and with the "jumpstart" method I also got video. So far, so good. But of course I got one cap with the wrong height so the lid of the supply won't close.
I'll probably recap the logic board as well while I'm at it.
I wouldn't think too hard about it. I've seen bodge used in this context several times, even in scenarios where a thing was done well but it's obvious that the repair isn't ideal and/or the need for the repair isn't ideal.
Once tolerances and timings tightened up enough, this kind of fix became unworkable/unreliable and so in relation to the way a faulty board might be tossed or reworked today (or even, IDK, in 1998) I'd say "bodge" is fair. The practice was normal, but it arguably wasn't the best possible repair, it just happened to be good enough and professionally installed and secured.
Due to increasing speeds and decreasing timing tolerances, "factory rework" had to change a lot through the course of the '90s, which is almost certainly why we don't see this kind of fix on significantly newer machines.
Just curious, no criticism implied:
Bodge (To do a clumsy or inelegant job, usually as a temporary repair; mend, patch up, repair.) has the wrong connotations for factory rework, which is very different today. It was an accepted industry practice some 30 years ago. PCB costs were high and skilled labor for testing and doing such fixes to 10mil/5mil tech PCBs was available and relatively inexpensive. While not elegant, rework patch wiring was done to a high standard as a permanent solution for design flaws, batch production glitches and individual boards that failed testing. The trace fixes we regularly do today "to mend, patch, repair" our damaged boards would not be considered bodge wires if done in a workmanlike manner, while fugly fixes would.
Are the connotations a bit different in the Netherlands? Very curious about that.
Wictionary: Middle Dutch botsen, butsen, boetsen (“to repair, patch”)
Hmm, that's weird.
I don't know much about this, but I think I've read in passing (while attempting to solve other problems) that symptoms like this can be indicative of either failed resistors or diodes somewhere in the affected circuit.
I guess you could check for burnt R's and D's and replace any that you find? It could be as simple as a broken solder joint too, so check any connections for continuity while your at it.
