    iMac A2438, destroyed capacitor and coil.

    Hi people.
    iMac A2438, board 820-02009-06. Some insect has killed itself destroying capacitor and coil next to it. No chance for buying donor board, so I'm asking you for help about values of destroyed components.

      So, using schematic and boardview for 820-02020_V1.0, I have replaced C7801, L7800 and APL1097 ic. iMac lives.

          Hi,

          820-02009 is an iMac. 820-02020 is a MacBook Pro. So, how you done that?

          Do you found the iMac boardview?

              Both boards have APL1097, so passives around them should be the same or very similar (even if layout will be different). I've compared both mainboards first and then found values using MacBook Pro schematic and boardview.

                  Help with capacitors

                  Hey, im fixing a imac logic board that has a damaged capacitor. The original capacitor says: 947 Sepc 270 16. I have looked through board viewer and traced it to the correct values: 270uf, 16v. Just as the original capacitor says. I cant find a direct replacement online for this capacitor. I have 239 Sepc 270 16 capacitors laying around, and compared to the original it's smaller. But is also 16v, 270uf. Can i replace it with this one? I cant really find specifications for them. Thanks

                  Hi people, I hope this is the correct spot to post this, I'm new to the forum.

                  I have an RTX 3080 Founders Edition which has a burnt up capacitor (it was in parallel with another capacitor which appears damaged too), so I am hoping to be able to identify the capacitor values and order replacements.

                  I hope these photos make it clear which component I am referring to:
                  (yes, the soldering is a bit botched from removing the blown one, I know)

                  I have found the board schematic (attached), but there does not seem to be a boardview available. I have never...

                  If I replace with inferior capacitor, Is it No harm to other IC components at all?
                  by chth96
                  I replaced some capacitor which is located on optical pickup pcb which is shown in the table below(PCB #2).Because it have been out of order.
                  Now,It works very well,But I just have found that all caps (6svpc100my and other part number as well) ,which is shown in the table below, has ultra-high ripple current spec.
                  It is not able to obtain any capacitor which can be a substitute for this ultra-high ripple current nichicon capacitor.
                  So I replaced it with samxon and rubycon's general capacitor(GP,YXA series).
                  I know that these capacitor will not last as long as nichicon capacitor...

                  How can I test non-polarized capacitor?
                  by chth96
                  I desoldered samwha NF capacitor(50v 5.6uf) from PCB circuit of 29inch CRT TV which have symptoms of no display after I heard sound of inrush of current to TV whenever I switch on this television.
                  I measured ESR value of this non-polarized capacitor(samwha NF capacitor 50v 5.6uf) by means of MESR-100 ESR meter and It displayed 0.3 ohm

                  And When I measured its capacitance with digital multimeter and LCR-T4 Mega328 meter, It displayed 10uf from DMM and 8uf from LCR-T4 meter.
                  I found catalogue of samwha capacitor(samwha-catalogue_3.pdf file), which is attached to this thread,...

                  Is it no harm to replace with capacitor without ripple current rating?
                  by chth96
                  When I tried to repair LG 29 inch CRT TV, I found that the ESR value of samyoung SMS capacitor(160v 2.2uf), which is very close to D1879 transistor, is 6 ohm.


                  Judging from above ESR Meter Table,I think It is necessary to replace this sms capacitor.So I visited local electronics shop,and I purchased 160v 2.2uf rubycon YK capacitor.
                  But when I browse through rubycon YK datasheet,I found that there is no ripple current rating for 160v 2.2uf specification. But On the contrary, I found 39 mA ripple current rating for 160v 2.2uf SMS capacitor.
                  Rubycon YK DataSheet (b...
