Re: capacitor with no esr value
As I re seated tcon cable and re assembled all the wires I turned it on and nothing no display untill I unplugged a cable form power supply to mainboard
here is a picture. Ihave no Idea where to check for know help.Last edited by 1supertech; 06-01-2012, 03:08 PM.Comment

Re: capacitor with no esr value
Do you have a multimeter? I assume since you have an ESR meter you will have one... Check the voltage on each of the pins going to the main board. I think this is a Harwa chassis - the wall mount bracket looks familiar.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: capacitor with no esr value
The red probe then goes on each voltage you want to measure. For the pins, you can apply a small amount of pressure to make contact with the metal surround in the connector.
Set your meter to DC 20V, if it is manually ranging. If it is autoranging, use volts or DC volts, whichever is available.
Repeat for each pin, noting down the voltage... don't round down report the exact value. If they fluctuate or change note this.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: capacitor with no esr value
Place the black probe in a spare screw hole of the chassis, this is your ground.

Now am I checking voltage with wires plugged in power supply and to main board ? I am checking voltage on the mainboard side.Last edited by 1supertech; 06-01-2012, 04:32 PM.Comment

Re: capacitor with no esr value
Does the power supply have any labelling near the connector indicating that is 3.3V output or something else? Are there any more outputs?Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: capacitor with no esr value
I have a feeling that main board has a short I have checked all caps and they have good Esr values about .25 ohms
Fuses on power supply test good all caps are good
I have no idea what else to check

by PrologHi 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... -
by chth96I 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...-

by chth96I 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,...-

by chth96When 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...-

by chth96a 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?...-
