    LG 42PC1D-EC with blown fuse and bad caps

    I have purchased an LG 42PC1D-EC that has 9 bulging caps on the power supply board and F2 250V 4A blown fuse on the ysus board. Could the bad caps be responsible for the blown fuse on the ysus board or should I be looking for something else?
    Any advice is greatly appreciated.

    The bad caps probably didn't cause the fuse to blow but it's likely that their high ESR over time killed something that caused the fuse to blow. It would help to post some high quality pictures

      It's possible that you have two separate issues. This PSU repair kit may correspond to your blown caps: http://www.ohmsupplies.co.uk/REPAIR-...-2300KEG002A-F

      I'd get the PSU running again then diagnose the Y-Sus.

        Thanks for the replies. I have caps ordered and hopefully here tomorrow. Once I have the PSU repaired should I replace the blown fuse and try again?

        I noticed another post with similar problems to mine here
        https://www.badcaps.net/forum/showthread.php?t=30613, is it highly probable that I have the same issue with the ysus?

          What is the part number of your Y-Sus? If it uses an IPM, then I'd say you have the same issue. Like I mentioned in that thread, there's also a possibility you have other damage on the Y-Sus.

              Ok, yes, I'd say you most likely have the same issue.

              There may better sources for replacement parts in UK, but here are a couple links:

              http://www.ebay.co.uk/sch/i.html?_tr...at=0&_from=R40

              http://www.ebay.co.uk/sch/i.html?_od...5-821&_sacat=0

              I've used startboy1010 on eBay numerous times.

                Many thanks for your advice, I'll check out your video on how to fit the part and weigh up my options.

                  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...

                  Asus UX490U laptop blown (caps?) on power board.
                  by odtech
                  Greetings friends.

                  I was given this nice little laptop and would like to revive it if possible but i'm stuck identifying blown components. I'm very new to the repair game so i'm proceeding very cautiously.

                  I don't know the history of this laptop and the donator didn't elaborate what happened but it seems some moisture got into the USB C charge port and the result was what looks like some blown caps. The tell is some gunk inside the USB C port and corrosion on the outside as well as what looks like corrosion around the blown components.

                  Any guidance...

                  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...

                  LG 47LB5DF blown power supply board
                  by cmlewis89
                  Hi folks,

                  I'm new to this forum. So my trusty 17-year-old LG 47" LCD recently died. As I was booting it up, I heard a hum followed by a loud bang, sounds of pieces flying around, and loss of power to the unit. Inspecting the PSU, I saw two obvious problems: a blown thermistor (bang + flung pieces) and a visibly bulging main cap. Inspecting as many components as I could with my Fluke MM, I diagnosed that the following components on the "hot side" of the board were also bad: one of the 2 main MOSFETs, main 8A fuse, small cap (25V 47uF) connected to main caps, and a blown...
