    question bout the caps

    now my board just got hit by this bug i believe because there is 3 that i can visibly see that have blown up but my question is can that take ur CPU out with it also, because I just purchased an Asus Nforce2 board and those are too expensive to take chances of sticking a fried cpu into it already...then loosing my new board in the process.

    My board supposidally gets power due to the light on it but it wont work, im guessing thats the symptoms of the caps but anyways Do the bad caps fry ur cpu also? or just the board

    it depends on whether or not the vrm blew up due to the bad caps.
    often when the vrm fet dies it can pass +5 or +12 onto vcore which means bye bye cpu.check for fets shorted s-d or rectifiers shorted.
    if none are found the cpu most likely survived.

      well could u tell me how to tell because I have no idea what VRM is...As far as I see none of them exploded but some expanded so I dont think it went critical but it did enough to my board to make it shut itself off..as far as the cpu wouldnt my bios shut if off if something like that happened..

      I do have a bios with a safe shut off feature and I think that would probably stop it from going weird like that whether it died from heat or what not...but How could I test it to make sure?

      btw I have a AMD Athlon XP1800+ with a Gigabyte 7vrx rev2.0 mobo

      i was reading up on vrms and it seems those are on intel systems and not amd, so what could be wrong and if anything what can i use to test these VRM's and what do they look like

        Correct me if I'm wrong. VRM = voltage regulating MOSFET

        These are the small squarish chips that are usually lying flat on the board with 2 leads on one side, located in the general vicinity of the socket and the caps. They get HOT under normal conditions. If one of those blew, you'd probably be able to see where the board underneath was discolored. Like it was burned.

          Actually VRM is a term for older boards standing for 'voltage regulator module', which back then were modules that unplugged from the board and could be upgraded/replaced if needed. Nowadays, they're all onboard the mainboard, but the name never changed...

            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.

            Assuming...

            Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
            Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...

            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...

            Replacing all the caps on the BenQ SW2700pt's power board didn't help...
            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...
