    MLT666 Rev 2.8 L - Smd capacitor

    Hello guys, I have this 32" Imperial Tv that "took it's time to show the video, now doens't turn on at all" to fix.
    The PSU is a MLT666 Rev 2.8L and as you can see from the pictures I'm attaching it has a lot of bad caps.
    So I turn it upside down and I see that cap completely gone, I'm sure it's a cap as it is drawn as such on the schematic but I don't have any idea about it's value, so I figured that's no point in doing any work if I'm gonna be stuck on that.

    Can somebody help me?

      That is just MLCC connected in parallel with the electrolytics caps for the 24VDC power supply output, it will be 0.1uF 50V rating.

              RTX 3080 FE Identifying capacitor
              by Prolog
              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...

              Should I replace polymer capacitor?
              by chth96
              a few days ago I finally purchased mser-100 v2 and I tested its abillity of measuring ESR value.
              I found that It shows pretty accurate ESR value for electrolytic capacitor,But When I measure polymer capacitor of dreamcast game console,I found that one third of polymer capacitor's ESR value is more than twice the value of ESR meter table.(for example, I measured one polymer capacitor of 6.3v 100uf, It showed ESR value of 7.68)
              Although my dreamcast now turns 20 years old but it still works. I occasionally have played game with it.
              Is this ESR value of polymer capacitor correct?...
