led lg 42lb5600 comes and goes backlight
friend I do not understand the given strip, forgive my ignorance but I do not know what I mean the led I try one
for one with a 9v battery with a 4k7 series resistor to lower the voltage and turn on all thanks.
camicor friend I would like to try the mosfet 60r580p could you tell me that I can replace it because it seems to me that it is bad but I do not get the same, thanks
Friend, the mafet transistor does not measure like a common transistor, the mosfet transcistor works like a suiche, computer. It has no base, collector, or emitter, instead of base it is called trigger. Instead of collector it is called drained, and instead of issuer it is called assortment.
How to measure it easily, facing the mosfet leg 1 would be (g) leg 2 would be (d) leg 3 would be (s), well you put the vultimeter on the scale of measuring diodes (continuity), the negative tip of the meter you put it on the leg (d) and the positive tip on the leg (s) will measure you a value around 400 to 500 and it can give a little more, after taking that measurement the pcitive tip you put it on the leg (g) without move the negative tip, you don't have to mark anything on the voltmeter, you turn and place the positive tip on the leg (s) and the voltmeter will give you a lower value than the initial one,
After those steps, bridge the 3 legs of the transistor, and repeat the process if it gives you the same measures, the mosfet is good but if the mosfet does nothing of the above and the vultimeter whistles or measures you in zeros, it is bad, I hope and serve you and comment on how it went,
