    Lg 60pv250 zsus

    I recently picked up a LG 60" plasma. It had a blown power fuse on the ZSUS or E board. After I replace the fuse I decided to check the circuit to try to see why the fuse blew. I found a ground on the VS pins. Both VS pins are grounded as is both sides of the fuse. I can't seem to find the component thats causing the circuit to be grounded. Also after disconnecting the 6 lead power cable coming over from the PS board. I turn it on and saw these crazy looking black splotches. Have to admit I've never seen this before. I am thinking about buying the repair kit that Shop Jimmy sells for this board but don't want to waste the money if the panel may be bad. Any input is appreciated.
    Thanks.

      Well I think you've narrowed it to a bad Zsus. The image is just because you have no zsus board running so I'd see that as a good sign really the rest is ok.

      I would think if you went by that kit then you should be able to find other devices shorted if you say Vsus is shorted to ground.

      Those large transistors would be a start. Either way you need a zzsus or or hopefully repair it or find someone who can like PTS electronics INC

          Thank you. That helps assure me that I'm not wasting a kit on a bad screen. I have a very good Pace soldering station with some nice accessories. So i'm pretty good with the soldering part. Thanks for your input.

              That kit will do the trick and then some, however I would install all parts if you don't know the board very well. Make sure to screw in all screws back in tightly before testing the tv or you will blow the board again.
              Good luck

                  I have the 60PZ750, Nick just reworked the Zsus board for me and did a fine job. I re-flowed every device on a heat sink and then some on the Ysus board..tightened every screw on every board. Cleaned the standoffs with Alcohol and Qtips on both Z and Y boards and installed the screws tightly.
                  Beautiful pictures.

                  Thanks Nick!

                      Hi there everyone, I have the exact same problem with my zsus board. I was wondering where I can buy the repair kit for the board and also @dbier63, did you end up fixing your fault??? If so do you know what component was causing the circuit ground??
                      regards Bikie

                          A funny fuse story – Lumix LX100 II
                          by corrize
                          Hello, I disassembled this dead camera, and found this WTF… Two fuses soldered one above the other !
                          I was pretty sure nobody touched it before, but that can't be from factory. There is flux, and capacitor is probably missing.
                          The other weird thing : the fuses are « G » fuse : (0.75A – 8V), seems very low. The original fuse should be « O » : (32V 2,5A).
                          There is « O » mark beside. All fuses have the same mark letter on main board. So, I can deduce it's a « O » fuse.
                          And this correspond to the issus I saw : when I plug the battery, I measure the voltage dropping...

                          Samsung UE46ES8000 Blown fuse but no other signs of short
                          by jesterace
                          Hi I wonder if anyone might be able to steer me in the right direction. I have this Samsung UE46ES8000 TV and it went bang during use. The main fuse on the PSU board is open. I've checked every diode/mosfet/transistor I can see and nothing appears to be short to cause the fuse to go. The DC output of the bridge rectifier is not short either. I've seen online that some of these models are known for having their PFC mosfet or other mosfets shorting and blowing the fuse but i'm not seeing that here. If anyone aware of these models having any issues to cause this? I'm reluctant to just replace the...

                          Help replacing fuse on my Mimaki CJV300-160 vinyl printer
                          by jshhh
                          Hi guys,

                          I'm inexperienced with electronics repairs, I've done a little bit of soldering caps and whatnot, but i have a blown fuse on this mimaki printer I got which I have bought a replacement for.

                          How do I remove this type of fuse (see picture)...it kinda looks like it would pull out of that bracket but it didn't come at first pull and I didn't want to brute force it incase it's soldered on there like most of the rest of the components.

                          Anybody know how to remove this type of fuse?

                          (The fuse is toward the bottom of the image labeled F2)...

                          Argon SA1 audio amplifier power-supply - fuse blown after fixing the short?
                          by Babbar
                          I found a project in the electronics trash yesterday. A nice Argon SA1 audio amp with some electrical issue. Took it apart and saw that the 4A250V fuse was blown so started lifting components to find the short. Eventually got to two MOSFETs (model FTA14N50C) that are shorted and when i took them out the short was gone.

                          Now i didn't have any replacements of the same model of course but i found a couple with pretty similar spec i thought (K10A60D & K12A50D) and put them in. Also replaced the blown fuse with a 3.5A250V one. Checked another time for short circuit and plugged it in....

                          Matsui 175S microwave fuse replacement
                          by drykid
                          Hi,

                          I recently picked up a used Matsui 175S microwave that was powering up (starts, turntable rotates) but not heating. From looking online the most likely culprit was the fuse, but unfortunately in this one the fuse had heated up and fused with the (badly designed) fuse holder and couldn't be removed. I guess this might indicate further issues beyond the fuse itself but at this stage I just want to replace the fuse and see how I go from there.

                          Anyway since I couldn't get out the fuse itself the easiest fix was to replace the fuse holder assembly that runs between the...
