Member: 1962081 Status: Offline Thanks Meter: 6 | iPad 2 Problem Blackilight i need help about a blacklight problem on ipad 2, i checked the motherboard and i seen that a capacitor was cracked, its the C2220 on the fisrt pic (i looked the reference on a Layer iPad 2), i removed this componment and i want to replace it by an other, so i found a capacitor on the web and i bought it and try to mount it on. After that, i try to check if the blacklight is ok but it still dont work. Can someone can say me if the capacitor that i bought is ok (reference on the second pic) and if not were can i buy this cap? i Know that in a lot of case it the D8228 Blacklight IC Chip and the L2220 Blacklight Filter but i think they are ok. Thanks |

Member: 81232 Status: Offline Thanks Meter: 196 | What knowledge do u have in electronics , as i see u have no clue about them . That cap is only an anti parasite capaciter , and his role is to filter . If u have an multimeter u can try to start measuring voltages , but first of all i think is better for u to start learning about components in ur ipad , and u wil understand how they all work . |

Member: 81232 Status: Offline Thanks Meter: 196 | If u check schematics there must be aroud 20 v on that cap , if there are not 20 v then the prob is from inverter . U need good skills to repair that kind of problem , u can try to change diode and coil from light boost ic . |
