jaugustine@verizon.net: Apr 07 01:34PM >F-F cable and also a F-M gender changer.   >(Or are they called sex-changers, given that gender is a grammatical >term and refers to words, not to people or cable ends?)   Hi Micky,   I did not mention that I have an extension cable removed from a broken laptop. This IDE extension has female connectors on both ends.   WHY GENDER CHANGER WON'T WORK:   I thought about a gender changer until I noticed that the "key" (blank spot, no pin connector) position was not in the center.   John

One of the reasons I'd like to get this > working is that the "car" remote for this unit doesn't work more than 2 feet > from the unit.   This is just a stupid comment that crossed my mind, but are you sure the remote for the radio is actually an infared and not rf or bluetooth or something else?   Just seems to me if it's a car radio, the remote would be for like gluing to the steering wheel or some place that if the radio was out of reach, which infared wouldn't work well. Plus it seems like it would work piss poor if the sun was beating down on the dashboard.   No explanation why the RS remote said it was learning the keys if this is the case but to me, within a car interior, rf would be a better answer than infared.   -bruce bje@ripco.com

Often these short when the supply loses regulation.   Mark Z.

No smoke, but a distinct sizzling noise > that lasted about 5 seconds before petering out.   Undervoltage on a SMPS causes high currents, so don't try to run it from a Variac at low voltage.   It's easy to see (black soot and melted metal) or sniff out (acrid smoky aroma) a failed component in this scenario. Pay attention to the pass transistor and the bridge rectifier, those frequently fail short (and a mains filter rarely fails at all). Also look for fusible resistors (they're marked like resistors, but act as fuses). If the pass transistor has failed (open or short), also check its base drive for damaged components.
