    bad capacitor

    hey everyone i am new and have a problem with my motherboard its a MSI MS-7548 and it has one blown capacitor and i was wondering should i replace it if its just one and what brand should i get to replace it also i heard i should go up a step like if the capacitor is a 6.3v 1000uf i should get a higher voltage so it doesn't blow again also it it normal that only one is bad i mean i looked at every one of them and only one is obvious this pic is not of my actual board but i just wanted to show you what one it is

      Re: bad capacitor

      As long as the manufacturer didn't screw up, there's no need to go up in voltage. Especially if that cap is already just filtering 3.3V or less... Higher voltage caps tend to have higher ESR so that's something to avoid too...

          While going up in voltage won't hurt anything (as long as the cap still has suitable specs.) in most cases it is not necessary. Most cap failures are a result of the use of poor quality caps not using caps not rated for the voltage used. You will also often run into issues with physical dimensions since higher voltage capacitors are often physically larger.

              I have some MSI motherboards where almost every capacitor is a Panasonic (good stuff), but a few 16V caps are Teapo (not so good). Is that what you have there?

                  I dubt these "Panasonic" are geniune. Because on my MSI PM8M3-V I see some Panasonic FL caps and Digi-key.com, nor Panasonic website, did not list any Panny FL caps at all...

                  Anyway, they are only d8, yet 16V - that is unusual alone. Not even old good Panny FM are made d8 and 1000uF in the 16V line:
                  http://www.digikey.com/scripts/dksea...=1563&PV63=489
                  They are d10, so, unless Panasonic made some special serie to the MSI (possible, but I'm highly doubtfull about it), they are fake.

                  Same for your mobo. Good Panasonic caps did not give up, mate

                      desoldered capacitor is self charging until 0.6 voltage.
                      by chth96
                      I have an 21 inch CRT TV which is not able to power on.
                      I disassembled 21 inch CRT TV and measured voltage of main filter capacitor(Samhwa HC 400WV 220uF) in the circuit.
                      It shows 270V on my DMM.

                      So I discharged this main filter capactior completely and detached circuit board from cathode-ray tube.
                      Then I desoldered this main filter capacitor from circuit board.
                      But I noticed that this desoldered large capacitor(Samhwa HC 400WV 220uF) is slowly charged by itself until it reached 0.6V

                      I measured its ESR value with MESR-100 and it shows 0.1 ohm,judging...

                      Samsung UN55NU6900F Standyby voltage is 1V higher than expected, is this a problem?
                      by tvguy12012012120
                      This is the zombie UN55NU6900F I wrote about in this original post.

                      It originally was completely dead with no standby voltage. After some poking around, I found the solder at RM819 (see pictures) failed. I removed it from the board, it tested fine, resoldered it, and now the TV works.

                      The expected standby voltage at the reference pin is specified to be 11.8V but it's reading 12.8V. Couple questions:

                      1. What could cause the standby voltage to be 1V higher than expected
                      2. Is this a problem
                      3. Could it have led to the failure at RM819, or was that...

                      Transformer producing higher voltage than rated
                      by UserXP
                      Hello, people.
                      i am not sure if this question belongs to this forum section exactly, but since there already are some queries here about power transformer, let's give it a try.

                      So, I have this old but very well preserved Casio SA-20 ToneBank keyboard. It is powered either by five 1.5V AA bateries, or via a power adapter, so its operating voltage is 7.5V. The power adapter input jack also states 7.5V DC In. Now, since this keyboard was never supplied with a PT, but actually came with test bateries included, I decided to try to buy an adapter for it. I know I could have just gone...

                      Capacitor detached from PCB – RTX 2070 Super Founders Edition

                      Title:
                      Capacitor detached from PCB – RTX 2070 Super Founders Edition

                      Description:
                      During maintenance on an RTX 2070 SUPER Founders Edition, I found a capacitor lying on my desk after reassembly.
                      I did not notice it detaching, so I am unsure of its original location on the PCB.

                      Procedure performed:
                      - Removed backplate
                      - Cleaned heatsink and PCB with isopropyl alcohol + soft ESD brush
                      - Reapplied thermal compound
                      - Reassembled card

                      Observed behavior after reassembly:
                      - GPU powers on and operates normally under...

                      Motor run capacitor physical size vs voltage rating & measurements?
                      by Per Hansson
                      (TL;DR skip the first paragraph)
                      I encountered my first dead motor run capacitor at a customer this week.
                      For some fields I guess it is a very common occurrence but the usual way for industrial machines here is to use 3-phase motors.
                      (Unless a servo motor makes more sense that is).
                      But for some reason this 3-phase machine uses a 1-phase motor for its liquid coolant pump.
                      The pump would run but sometimes trip the 10A breaker.
                      I monitored it starting and stopping for over an hour until it finally stopped in a specific spot between its windings:
                      Then it could...
