    Westinghouse LCM-22w3

    DA-19M009 power supply to an A220Z1-Z01-H-S6 video board. Dead before and after replacing power supply caps, no power light at all. Checked big cap and has 168v, pulled one leg of glass fuse to see if it would give me the power light operation it did not so put leg of fuse back. This info was gleaned from an old post here. Looking to see if I could use others information to repair my monitor. Another post asked for the resistance of F1 which was 0.3 ohms, U6 voltages on the three legs which read 0v, 1.7v, and 2.7v. Finally U7 voltages which read 0v, 1.4v, and 2.4v. Any suggestions on what to do to revive this would be appreciated.

    What voltages do you have on:
    CE104 (should be +5v)
    CE101 (should be +19v)

    I believe U6 is a the 3.3v regulator (Panel_vcc), the input comes from the +5 volts from the power supply

      Didn't jump out on a Google search, can you tell me their location so I can test?

        Check on the plug between the power supply and the logic board, the voltages are marked. you should have 13.8v and 5v
        The capacitors, CE10x are marked on the power supply board

          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...

          Powersupply has all the voltages - Monitor still no power
          by Capacitorial
          Hello guys,

          I have a Philips 240B7QPJEB. The monitor seems completely dead.
          I opened it and measured the voltages of the powersupply. I found that a mosfet was dead and replaced it.
          On the connector, that goes to the TCON board, all voltages 15-19V and 5V are present.
          The small connector on the left of the PSU has two cables with 18V and all the other have 0.2V. It connects on this small connector on the left ontop of the panel. I guess the backlight? Seens fine I guess.
          The weird thing is, that the Power LED is powered over the TCON board.
          On The TCON...

          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....
