    Fishing trolley faulty....again

    Sir scooby . . . . . Your first encounter was a cake walk, compared to your evolved situation this time. You had a shorted Drain to Source on the power FET and that effectively had the unit running full speed, just as soon as the unit was turned on. So you replaced the shorted POWER FET and...

    Fishing trolley faulty....again

    Sir scooby . . . . . (doo ? ) That might be a tougher one, this time around , with your professed and limited apprehension of electronics circuitry. On the units controller board I only see 3 discrete surface mount micro transistors and a 3 terminal regulator IC. (And those 3 transistors...

    Dead CPU fan - Can You ID this part?

    I take it that this thermal sensor should not be open like it is? I have seen some sensors actually being 100K ohms resistance . . . . . so that one might be in the same catagory . . . but you would be able to see the resistance shift as heated with a blow drier.

    Dead CPU fan - Can You ID this part?

    Thats a thermal sensor, sampling air over fan temperature and telling the internal motor control circitry when to kick into HIGH speed . . . . . and accordingly . . . when it can drop back down to normal speed. Also you may need near a full 12VDC on that fan for it to kick off.. 73's de Edd...

    Missing proprietary AV in/out cable - probing pins ok ? Hitach VM-H39A camcorder

    You done such a good job of loosing the AV cable assembly . . . . . did you do as well, in ALSO loosing its RF modulator which was also packed with that unit. It can also plug into that connector . . . . If so, then it would give you an AF modulated channel 3 or 4 TV signal which you could...
