    Anybody seen Panasonic caps failing?

    I just wondering if anybody of you guys here seen LowESR Panasonic caps (FR, FM, FC Series) failing? I'm using these many many years now when I'm doing repairs but never got one device back with one of the replaced caps failing.
    Second question I am really curious about: are there any device that are natively populated with these caps mentioned above? I personally have never seen any of them in consumer electronics, PC components or whatever - not even in medical devices (AGFA prefers the use of Oscon there)!

      I've seen them fail in Panasonic TV's, usually around the 10 year mark.

          Some older 2007-2008 plasmas had a few bad Panasonics, but usually small value general purpose near big hot heatsinks, so less likely to be an issue in normal applications.

              normally due to lifespan... a decade of usage or exposed in high heat

                  dont remember what series but seen leakers in panasonic built viewsonic 21" monitors.
                  a few caused fires!
                  cant blame the caps though.these were packed in tight with hot parts.design flaw.

                      I will agree too about the 10 year mark, and this is not the limit.
                      SONY CRT monitor failed after 12 years, all caps were in top shape and I use them as spare parts in other repairs.
                      ESR tested by the DE-5000 all of them was as new.

                          I too have successfully used Chemicon and Panasonic caps from 10-12 years old CRT monitors to fix 3-4 year old LCD TVs. They will likely last another 4-5 years as they weren't stressed too much in those big beasts, plenty of room inside.

                          A working TV? How boring!

                              Seasonic B12 BC-550 – barely 2 years old and with BAD CAPS already!
                              by momaka
                              I know I've been a little scarce lately (like the last 2-3 years), but I'm still here and still doing my thing with fixing PSUs.

                              For today's considerations, I have a Seasonic B12 BC-550 [A551bcafh] 550 Watt ATX power supply for you (click on links for full size images).

                              https://www.badcaps.net/filedata/fetch?id=3591772

                              It's a modern ATX unit with fixed (non-modular) cables and an 80-plus bronze certificate. Here's the label:

                              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."
                              ...

                              Hello!

                              I have two projects on my work bench. One is a friends dead JBL Xtreme speaker with a blown voltage regulator and corresponding bulged and shorted cap. That cap has clear markings so I know what replacement I need for it.

                              The other project however is a whole different deal. It's a Zoom 9000 guitar effect from the 90th that has developed a devil hound howl when there is no input from the guitar. I'm guessing caps problem. So, since I don't really use this effect anymore I thought it would be a perfect project to learn on.

                              I have studied the board and...

                              EVGA e-GeForce 7600 GS AGP 256MD2 [256-A8-N542-T2] with bad caps - fixed
                              by momaka
                              I did it again – I had to fulfill my inner desire to fix yet another old piece of hardware. This one is actually kind of worthwhile, too – it’s an EVGA e-GeForce 7600 GS AGP video card, model P/N: 256-A8-N542-T2. With the popularity of “retro” PCs from the Win9x to XP era going up, and the diminishing supply of decent AGP cards, it is expected their prices will go up. Or is it? I bought the this video card rather on the cheap side (~$9 USD shipped to my door), because the eBay seller listed it for parts or repair (and correctly noted the bad capacitors.)

                              So, here is the...

                              Replacement caps for Samson Resolv studio monitor 65A Amp board.
                              by black6host
                              Good day!

                              I have a Samson Resolv studio monitor that has no sound output. I've opened it up and found two caps that are bulging on what I believe to be the power supply section of the amplifier board. The board is marked Resolv 65A AMP V1.2. The caps in question are YUSCON, 2200uF, 35V, 85C temp and have markings of RA(P) and are 16mm x 25.5mm tall. I've attached the schematic and the caps in question are C5 and C6. I'm assuming they are low esr caps. I've tested both caps and they test low uF, nowhere near 2200uF.

                              I'm going to replace the caps and I'll be the first...
