    Wharfdale 32" TV dead but fuse ok (Vestel PSU)

    Hi

    Given a dead one of these to play with and it has a Vestel 17pw15-9 PSU in it. With all the connections unplugged I could see 24v, which fades away to nothing when I plug back in the cable to the main board.

    I can see there is a repair kit that covers stuck in standby, but I wanted to be a little more sure of the fault before ordering.

    The 5v reg tests good, even with 120ohm resistor as the load. The two main culprit capacitors read as 15nf or thereabouts.

    Checked the electroytic caps with the Peak and nothing with a high ESR.

    Other threads suggested bringing the PSU out of standby, but not too sure how that happens.

    Any suggestions what to check next?

          Lenovo Thinkpad E15 Gen 2 NM-D011 - No display ? External , yes!

          Here is a pretty crazy one.

          Step 1.
          Laptop was brought to me as dead not working. Removed everything , cleared everything.
          Step 2.
          Some liquid damage close to the Type - C connector, and the connector even though it was cleaned wasn't charging the battery . Removed the Type-C port, and replaced it. Now the laptop turns on and charges battery. Shows external screen , not internal.
          Step 3.
          Took out the screen and checked it to a secondary Gen 2 i have, screen works like a charm.
          Step 4.
          Lets ,dive into the board. I see the edp cable on the...

          Samsung 55NU6900 - Heard a pop then tv is dead, burnt cap & dead fuse
          by Pwtzz
          Hi All,

          Before replacing what I know to be bad even with my novice experience. What I have checked at the moment is the fuse and the obvious burnt capacitor. I haven't bought any replacement parts yet.
          I still have no idea how this happened but could just be plain old turned bad. What other stuff should I consider buying as replacement? thanks in advance.

          Edit: I saw that a replacement board can be had for about $50. I would rather attempt to fix before just replacement the board.

          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)...
