iPad 2 Problem Blackilight $ ios version issue ios/hardware , assistance please

On March 27, 2015, Posted by , In iPhone, With Comments Off on iPad 2 Problem Blackilight $ ios version issue ios/hardware , assistance please

hello,


i want to be helped 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 purchase 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

    Check or change D8228 and L2200 one by one.
    Make sure C2200 is not shorted to ground on both sides.

    Thanks for your reply, How can i test the c2220? And the componment that i bought Along with the référence on the 2nd pic, is its ok for replace?

    Regards

    sorry but im sûre that the c2220 is important for blacklight, if it not in place, the blacklight dont Work.
    I want to Know if the componment that i bought ( pic 2) is the same as the last pic (pic 3)

    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 .

    Ok so can u say me where i can purchase this cap?
    You said i can measure the voltage but of what? I cant measure voltage on cap???

  8. wagny says:

    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 want good skills to repair that kind of problem , u can try to change diode and coil from light boost ic .

    Check or change D8228 and L2200 one by one.

    Hello,
    So i replace the diode and it dont solve my problem, i checked the filter and there is a continuity so its ok too…
    Can someone have an other idea?
    Is someone know where i can purchase the C2220?
    I will post a pic but all is clear

    Regards

    Its an ipad2 wifi and The c8232 and the l2200 are not on motherbord, only a componment on the right of the d8228, and i dont know what is it. (3rd pic Brown componment)

  13. tavenger5 says:

    So for i Think i found the problem, the grey cap that i put on the third pic is not the good componment, i removed it and i made a jumper and the blacklight is working!!!!!
    So i Think its the place for L2200 is anyone can confirm???

    Regards
