    Replace all caps or just the main power source for CPU?

    I have about 8-9 older MBs that prob need caps replaced.. I've done this plenty of times in the past as not a big deal but the big deal with doing this many boards is the cost..

    Do I just replace the clear bad looking caps or is it common to just replace all of them?

    I would of course replace all of the group of caps if one or 2 is bad from the same group (same type and make).

    Usually I would just replace the main large caps that are near the CPU but wondering if all of them would need to be replaced or maybe its uncommon for samller caps to be fine after 10-15 years?

    One board I was using recently for an old school gaming rig was doing the usuall signs of bad caps with not wanting to post.. most of the time I would hit the power button and it would power up for 5 secs and then shut off.. I would have to hit the power button quiet a few times before it would finally stay on and post.. sometimes it would hang on post.

    Figured that one has bad caps but when looking at the caps over and over theres no clear bulging caps to be found.. but after reading about a strong ammonia smell is a sign then its gota be what it is.

    Think I put this thread in the wrong spot so please remove it.

      I don't think it is the wrong forum thread at all.

      Yes, you should replace all the large ones, even if they haven't bulged (they might fail soon, or they might have dried out inside). By 'the large ones', I mean the ones rated at 100uF and greater.

      P.S. Got any pics? We love pics here on this forum

      About that computer with no visible bad caps: what brand of PSU does it have, and have you looked inside the PSU yet? It's a good idea to check all the PSU's for bad capacitors!

        The photos on this forum are very good, but the equipment is probably of high order and expensive. What cameras and attachments are typically used?

            Is it possible to upgrade from a Vestel 17MB97 main board to a 17MB110 Main board?
            by cheeky2
            I suppose the real question is whether the existing pinouts from ether a 17IPS71 psu are cross compatible with a 17IPS12 psu? If they are then the exchange of the main boards should have no issues providing the screen is compatible with both main boards. Obviously you can change the screen configurations easily enough (providing you have the correct files) for the main board. Why may you ask would I do this? Well a lot of the smart features are no longer working on a Hitachi 48HBT62U main board I wish to give it a new lease of life!
            Obviously the same LVDS connector for the screen connection...

            Identifying caps on an old Zoom 9000
            by Paxman_Swede
            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...

            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...

            Trying to learn electronics repair as a hobby. I have no formal training in electronics, circuits, etc. Everything I know, which isn't much, has been learned from watching youtube videos, reading books, forums, etc. This means, sometimes I have a hard time understanding and interpreting what's important when I look at datasheets, and such.

            My brother has a TV that I'm working on now. He said he was watching it, he heard a loud pop and it went off. I used my DMM to check the fuse, it was blown. From watching lots of hours of electronics repairs on youtube, I figured that was just a...
