    Help fixing TV Panasonic TX-P42UT30E

    Sir Cevi . . . . . OBSERVATIONS . . . On your photos of post 10, in actuality, both part configurations being drawn in are incorrect. To amend, you go to the right, to see the two connections and draw in a 5 ohm resistor that is being in series with a thermal fuse link. They connect to that...

    Mobility scooter power module won't charge

    Sir Bill . . . . . Back when you measured 65VDC . . . if you had the probes in the right place, along with that diode being open circuit, I could see 12VDC [PLUS] 12VDC [PLUS] 24VDC from the charger AND its additional surplus voltage put out since there was being NO LOADING placed upon it...

    U2008B - ac motor speed controller with soft start

    Sir Lautrec . . . . OBSERVATIONS: You definitely need to LEAVE the R6 shunt sampling resistor in circuit. You need to stop trying the GRINDER and plug in a small electric drill to initially then evaluate that units (probable meager) capabilities. ANGLE GRINDERS . . . my units and experiences...

    Relay differences

    I also read the current pull of the valve as being 2.7 A , but then just compared that value to what the "overkill" cushion margin, that the relays contacts would be providing at 30 A. And yes, it looks like that OMRON at its 10A would be a like 1/2 size replacement with out all of the...

    Relay differences

    Sir YODA . . . . . " foil membrane switches are rated for 30mA. Ill check with JD on that tomorrow too." With due consideration of your doing your own researching out, in order to find the current passing thru the membrane switch. I'll just bet you that "ole' Joe Blow on the factory phone...

    Relay differences

    Sir YODA . . . . . Looking between the specs of both of your sub relay substitutes , they meet the specs or even exceed the power carrying capacity specs of that pricier sub compact half relay. Your "sensitive switch" loop circuitry will only be carrying the paltry ~2 watts that is required...

    Can someone help me ID 2 components pleased?

    Sir Kevin . . . . . . .m34232? Isn't that connector being where your units wall wart plugs into and then the power input initially routes down to TP's 1 and 2, where they then encounter THE referenced EMI / RFI ( "CRAP" ) filter ? And then, if its two coils are intact, the power...

    Sir Gang_wheell . . . . . CONCEPT of DESIGN . . . . . However, in this case you are severely limiting that by ONLY submittintg the components side views of PCB's. Your power supply is contained within the very central area of the frontal daughter PCB that is being flipped over and supported...
