    Recap also the polymer caps?

    Quick question on the Polymer Capacitors. I have a dead board with defective/cheap capacitors, all Jackson. I am going to replace the Aluminum Electrolytic Capacitors(vented), but should I replace the Polymer ones(non vented) too?

    The Aluminum Electrolytic Capacitors are not flat at the top which is why Im replacing them. The polymer ones looks normal. Should I be worried with these (being a Jackson brand and all) or can I just leave them alone?

      what board are you talking about? can you provide a pic of the polymer caps to avoid confusion. what values are at the top of these polymer caps.

          The board is ABIT SA6R. Heres a pic of what Im talking about, sorry only camera I have is a camera phone. These are the smaller caps. The one just to the left (not circled in red) is the bad cap that Im going to replace (Jackson 1500uf 6.3v). Just wondering if I needed to replace the smaller caps circled in red (Jackson 100uf 10v)

              i dont think they are polymer caps, just low value normal electrolytics. if they are only 100uf, should be fine if you leave them. If they dont have vents then they are using a different kind of electrolyte. it is rare to see them fail but sometimes they do. I did a few abit boards like that leaving them, still stable as hell.

              Make sure you replace all the jackcon 1000uf and above, they are total crap. they can bust out their bungs at the bottom of the cap and leak electrolyte all over the board. if you have leaked electrolyte you can clean it from the board and smt components using alcohol and a cotton swab. You do that when you have removed capacitors in the area and before you install the new ones.

              i hope you have success, it looks like a nice board.

                  Thanks for the helpful info willawake!! The board has been sitting in my closet for a couple years now becuase of the caps. Now I have enough info to fix it, luckily I didnt toss out the board

                      by momaka
                      Normally, I never post repairs this quick after I do them, because… I am usually very slow. But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...

                      Aluminum SMD caps vs thru hole caps (reliability)
                      by 13mh13
                      The PCB motor for 1987 Technics SLP-120 CD player has slow spin-up issues. Similar to what another tech in the below video reported.

                      I replaced the three bi-polar 47uF electros but that made no difference. The orig three bi-polar 47uF electros tested okay on my ESR M-tester.
                      I have not tested/replaced those alum. SMD electro PCB caps.
                      Are Al smd caps are more prone to failure (or degradation) than regular thru-hole electros?
                      All the thru hole electros I removed / replaced on this CDP (and most...

                      FORD 1996 ECU RECAP: Aluminum - Polymer worth bothering?
                      by Cartel
                      I will be pulling my crown vic ECU and recapping it. 3 in total, 47uf 16v x2 and a 10uf 63v
                      I hope they havent puked yet. I was thinking of replacing them with Aluminum - Polymer thru hole caps. probably 47uf 25v and 10uf 80v
                      They arent cheap. Anyone have any experience with them? Am I wasing my money on premium caps?

                      Nichicon PLV series

                      thanks

                      Heathkit IO-4205 Power Supply Caps
                      by eryjus
                      Hello,

                      First, I am a complete noob with high voltage stuff. I'm learning, but I need help by someone looking over my shoulder.

                      I recently came into posession of a Heathkit IO-4205 5MHz Dual Trace Oscilloscope. The documentation is copyright 1978. I'm told it works.

                      I opened it up to check the caps before I applied power, and found the following black caps and wanted to know what they were. They are on the power supply board. I was able to read the name and model and came up with, "Nytronics 162J-1, 0.1uF, 20% tolerance, 2000VDC."
                      ...

                      After updating motherboard capacitors, what to do next (Asrock K7VT2, SOLTEK SL-75FRN2L)
                      by dragon3x
                      Hi, I have some 32 bits computer motherboards that need repair, as they fail to
                      power on.

                      Here are some examples :

                      (N.B. "capacitors" indicated here are electrolytic capacitors located in the onboard
                      switching supply area).
                      (N.B. #2 : I could not find a 3300 microF aluminum-polymer with a higher voltage
                      than 6.3 V.)

                      1 - Motherboard #1 : this is an Asrock K7VT2 (socket A) that still works well. To put it on test
                      I replaced capacitors with aluminum-polymer.
                      3300 microF/6.3 V. x 4 replaced by 3300 microF/6.3 V. (KYOCERA...
