    wrt54gs v2 whineing

    I have a wrt54gs v2 that's recently started whineing near the inductors/capacitors but im unable to locate the exact source. I was wondering if maybe one of the hermei caps were blown without bulging and if I could replace them with what I have laying around. Hermei caps are 220uf 25v ht series and I have some nichicon 220uf 50v and a 470uf 50v all vr(m). This thing is heatsinked fanned overclocked and tx boosted so im really pushing the power designed of the board.

    Ps the whineing just started a couple months ago with no hardware or settings changes in over a year. Its running off a 1.5amp switching power supply and I've tried swapping it. None of my other wrt54g or gs routers are whineing so I don't think its the power supply. Thanks

      post a pic.i poly these.330/16 sep input.560/4 sepc +3.3 output.
      its worth it to poly it.

          My phone isn't wanting to let me upload but here's a random pic of the same board http://img392.*************/img392/7...74smallix4.jpg the only difference is I used bigger heatsinks I cut up from a p3.

          Im looking to get this up and running again as cheap as I can, and looking around I have 1 nichicon 470uf50v vr(m) 1 nichicon 220uf50v vr(m) and a ton of green caps labled "tracon 2a474k" and "tracon 2a224k" which I believe are polyester film. Any of these work if you think I need a recap? Im having no luck with my usual datasheet sources for the tracon caps

              those are what i use.vr are gp caps.cant help on the tracons.

                  Figured the tracon caps out. 2a is voltage in number of zeros, so 100v, 224 is capacitence in pictofarads with the third digit being the number of zeros, so in this case .22uf. K is the series but I've not found anything out about what it means. Anyways these deffinately wont work. Thanks for the links kc, im assumeing I test to see which caps have what voltage and use the poly with the higher voltage where I have to and use the 4v ones where I can for better ripple. Just want to double check, you know you make an ASS-u-ME if you end up being wrong. Thanks

                      NAD C320BEE repair possibly bad capacitors
                      by Alfieh
                      hey Im very new to repairing electronics with capacitors as well as using a multimeter so I need so help/guidance fixing this issue

                      recently I was handed a family members old NAD C320BEE that they had in their loft for storage for a few years but when powered on it went into power safety mode due to a problem on the protection circuit somewhere before it went into storage I was told it worked fine I found lots of people online talking about how the capasitors are known to be pretty bad in this model and can cause this issue the only problem being I don't have much experience sorting...

                      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...

                      Onkyo TX-SR607 HDMI problem showing a black screen intermittently
                      by redwire
                      Onkyo TX-SR607 HDMI problem showing a black screen intermittently, audio was OK.
                      It would usually cut out a few minutes after power on, for maybe 1 minute then work OK, then cut out and go to black again. Or fade out to sparkles and noisy video.

                      Well known is these boards need recapping and there is a strange mix of parts on both sides of the board.

                      The bottom of the board has 100uF 4V (5.3*5.3mm, qty 5) and 220uF 4V (6.6*6.6mm, qty 5).
                      Per the service bulletin, an issue is the Toshiba LDO's want low ESR for stability so I went with 100uF 6.3V polymer...

                      The switch has served me for 10+ years (was new when I bought it). It's a nice switch with connections on the back which makes for quite a clean desk. Reason for taking it apart was that the cooling fan was noisy so I expected it to be dirty/dusty inside and the need to order a new fan. What I found was that it was very dirty/dusty and some electrolytic capacitors which needs attention. There are 3 capacitors which needs to be replaced but the ESR on some of the other ones might be bad as well so I think I'll replace them all. Original...

                      Picking caps for Antec SU-380
                      by ajdrenter
                      In my search for a proper 5v heavy ATX power supply, I selected an old Antec SU-380 that I've had in storage for a long time. Opening the power supply reveals a couple bulged capacitors. I removed all the caps and made a map for myself. I found the datasheet for the PCE TUR series in this thread:
                      https://www.badcaps.net/forum/showthread.php?t=14159
                      It says these are general purpose, so I assume I can replace them with any general purpose capacitors, but I don't really know anything about power supply circuits or reading capacitor datasheets. Despite this, I've been shopping for replacements:...
