    Via P4PB400-FL Bad caps

    I Heard about the capacitor problem about two years ago so once a month I would pull the side and check my board.

    Last month it was fine this month yesterday it's not the top of the 7 large caps around the processor are swelling with a little leakage this is on a mission critical machine so I may try to replace the caps some weekend soon.

    The caps look like 10mm but I can't see the numbers without pulling the board and I can't do that right now.

    Anyone know what the number is for the 7 large caps around the processor on the VIA P4PB400-FL board.

    Thanks

    Re: Via P4PB400-FL Bad caps

    what brand are the caps?

    i see the board here but not possible to read the caps
    http://accelenation.com/?ac.id.184.1

    are all the caps the same brand. there is quite a few. If they are all a crappy brand i would normally recommend to replace all 1000uf and above. because it is a misson critical system i absolutely insist on that.

    looks like you have 11 major values and 19 or more probably 1000s. better to open the case and check with a magnifying glass and torch at least.

      Yep I will have to get a magnifying glass to know for sure. But from the color and marking I first thought "rubycon"
      But I will take a closer look in a few days.

      They all look to be the same brand but will post if they are for sure in a day or two.

      Thanks

        they are GSC brand....crap

        http://www.computerbase.de/bild/article/125/20/

        11 major and 24 probably 1000s. a hell of a lot of caps. you would really have to love that board to do all that work. i would probably look for an intel D875PBZLK on ebay. anyway nice project, with all good caps it will run as the designers intended.

        nice to see that GSC are being consistent on p4 age of boards

          Hi,

          I have one VIA P4PB-400 and one VIA P4PB-Ultra.

          The 400 has bad caps and was locking up. I replaced it with the Ultra, it was a spare with very few hours on it. I'm sure it will eventually fail too. It has the same GSC caps in it.


          My count of the caps is this:

          6.3V
          8mmx12mm 1000uF 21 pcs
          10 x 25 2200uF 7 pcs

          10V
          8 x 14 1000uF 5 pcs

          16V
          10 x 20 1000uF 4 pcs

          At $1.10 each, that's $40.70 (plus shipping) for each board.

          I just bid on a 875PBZLK for $47.50. I actually have two PCs with the 875PBZ (no LK) and they are good boards. The only problem is if I change boards, I'll have to buy a new copy of WinXP, at around $150 recapping suddenly makes sense.

          What do you think, are the caps I need available from Top Cat. I looked around on the net and didn't find everything I would need. I would only recap one board (Ultra), unless two would somehow be cheaper.

              I'm in the Milwaukee, Wisconsin (USA) area.

              I've looked in the local business yellow pages, there are one or two places I could try. I thought that a local source may have some of the harder to get caps.

              Other than that, I checked the USA places recommended in the "where to buy caps" thread.

              Thanks for any help,

              Paul

                Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
                by Tynan Dill
                I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

                Upon bringing it home and plugging it up, it showed a standby light.

                I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

                The screen seems to blackout and stay black, but with a flashlight I can see the display.

                With my Playstation 4 connected via HDMI, and running a game I can hear sound.

                Sceptre U550CV-UMR 4K LED, Bad Caps on Main Power Board?
                by Dani_2024
                Hi and thanks in advance for any input you might provide!
                I have a Sceptre U550CV-UMRD8POTV83BB 4K LED (this is a dumb tv) that I bought new in August 2021, so It's just completed 3 years.
                Main power board model: TP.MS3683.PC821 T-Con board: N4TP546UHDPU2L_BO

                Last Sunday I was watching a dvd and fell asleep for about half hour, when I awoke the tv screen was black and couldn't get the dvd menu to show, so I changed the input to antenna and had sound but no picture, turned it off. I then got online and found this great site! ....read many troubleshooting tips and this...

                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...

                by Noodneek
                My 3.5 years old monitor (BenQ SW2700pt) started to black out for 1-2 sec every minute or so, it was doing this even with PC disconnected from it. I searched online and read that it's probably aging capacitors and there's a workaround to lower the brightness.

                I lowered it from 100 to 65% and it indeed helped, but after a couple of months the issue returned... I continued to lower the brightness, but it helped only for a couple of hours at most, then I needed to lower it further... Turning the monitor off and waiting for it to cool down also helped for a short time, after which it...
