laptop service in Hyderabad  "so first of all let's check the fuse" "everybody knows these dead out test fuse" "but it's just for beginners when we" "touch this probes at this both of them" "the buzzer should be so it means that" "the fuse is okay and now this is the" "fuse that is burst as you can see it is" "burst inside and let's check this one so" "the buzzer is not beeping X mainly this" "is the bad one now it is the ceramic" "type fuse so reject them we cannot see" "the see the thin wire inside this so it" "is the the ceramic type s Q so we will" "have to check this with meter as you can" "as you can hear the sound that it" Dell laptop service in Hyderabad  "beeping so it is the good one if does" "not be so it that is the bad one so now" "it was the fuse so now let's check the"

"between this wires and while to call s" "there is not continuity between the coil" "so the inductor is bad so let's check" this "so it means this coil is okay let's" "check this one it's also okay it is also" "okay okay so means this inductor is okay" "and we can reuse this in any circuit so" "this was the testing of inductors if" "there is not continuity between this so" "means this is not okay that is bad one" "if there is continuity between this legs" hp laptop service in Hyderabad  "this side of any one of the this side so" "this yes there would be a short circuit" "so that is also a bad one there's also" laptop service center in Hyderabad   "the inductors with four legs" "it's okay so is the good one" "these two are also inductor so the" "method is same as there should be"

okay" "let's like this call so it is also okay" "but there should not be continually like" "this from this side to this side if" "there is continuity so this is the short" "circuit so that is the dead one" "there should not contain tip there" "should be there should not any" "continuity in lag this side so this is" "the okay transformer and we have now we" sony laptop service center in Hyderabad  "have some disturb of transformer so the" "same same method will have to check this" "the buzzer should beep in all of these" "legs the one probe is here there should" "be continue with all these big

continue like this" "so this is also the good transformer so" "the same way" "so this is also a good one now we are" "going to check the resistance we will" "have to move this selector to ohms so" cheap laptop repair in hyderabad  "now first of all child s check this" "so if it's a good register and it showed" "its 100 on register so there is 99.9 so" "this is also a good register let's check" "this one so now it's I think it's 1k so" "that's it let's select the to cake range" laptop spares and service center in Hyderabad  "so it's about 1k nine nine two" "so it's nine and 200 means 1000 ohms is" "equal to 1 K 1 kilo ohm so it's a 1k on" "the which means is also good let's check" "this one so it's about 1.5 K so this is" "also good resistance now let's check the" "non polar
