Correcting a few errors. The black and the brown connectors require the same 0.16mm thickness at the ribbon ends, the "black" one has more metal and seemed thicker. The brown one has cable entry nearest the brown piece and bare lands nearest the pcb. Opposite for the "black" one , ribbon entry farthest from the black bit and bare lands away from the pcb. -- Diverse Devices, Southampton, England electronic...

snip From a personal perspective, I 'grew up' with analog power supplies (often using vacuum tube rectifiers). These were inefficient, but easy to repair. The switch to SMPS supplies required more sophisticated techniques, but in the end was not that much more difficult, even for the multiple output supplies found in PCs. At this point I am finding the supplies in LCD TVs to be extremely difficult to troubleshoot safely and...

What can I do for you? I appreciate the kind offer, but I was referring to myself as Captain Stupid.

It's price that driving the decline in quality. Running the operating temperature and voltages near the point of failure is one way to save on costs. They wouldn't make junk if consumers didn't demand low prices. There are usually...

Looking at the schematic, if there were such a jumper it also would null at 200 ohms when the "range expander" switch is on, and it doesn't. I think when I get time I'm going to check the transformer windings for continuity...maybe someone transmitted into it and...

Sylvia Else wrote: Leaving the neutral failure issue aside, what would happen if I disabled the Earth leakage detectors and drew power across the two phases. Would the two utility meters correctly reflect the energy I consumed? Sylvia. On second thoughts, it's pretty obvious that they wouldn't be correct, and that I'd be significantly overcharged for the power. Sylvia.

There appears to be a race for the bearings on one end of the shaft, the end with the metal fan, and the race spins freely on the shaft. The other side of the shaft, which had the white plastic fan, looks pretty loose, and the only force holding the shaft in place there seems to be 2 springloaded opposing metal...
