    Tecknika 40" lcd tv blown psu still working

    Hello dear technicians .

    It was a sunny day outside and friend of mine came to me with this tv.
    like the sais the tv powers up but it made a freaking fume that made basement unworkable for 1 hour.

    So rather not spend some money and let the tv open untill the psu comes from ebay maybe someone can help me with some parts identification.

    The big ex red now bron cap and something ex brown with rt1 marking near.

    G0281d psu model v:0.0

    Even after one week the psu stinks omg

    Thank you

      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...

      HP X360 convertible battery blown fuse error, not charging
      by drscoot
      HP Modelnumber: 14-dh0061nb​
      This laptop had a shorted cap on a Vcore section. After replacement is works again. But there is still a battery issue.
      The battery is HT03XL and with the built-in component test from HP, in the Power section, I get an error: Logic State: Calibration required (20), Charge state: Blown Fuse (42)
      I have another same battery, also with error: Logic State: Very Weak (70), Charge state: Blown Fuse (42)
      And a third battery TF03XL (looks identical) with error: Logic State: OK (0), Charge state: Blown Fuse (42)
      All these 3 batteries are charging...

      Part selection for possible blown inductor on ASUS GX531-GW-AB76 laptop mobo
      by swerg
      Hey everyone,

      I'm a novice trying to repair my laptop. The LCD screen has an image, but no LED backlight for the image. It also produces an image when connected to an external monitor.
      I have found what I believe to be a blown inductor labeled "L4502" and "120 Ohm" in the schematics (zoomed in image, blue arrow to blown component). I have included an image of the general area of the mobo and an excerpt from the schematics as well.
      I am having trouble selecting a replacement component, which I believe to be a 120 Ohm ferrite bead, from the components...

      Blown fuses on Gigabyte GTX 980TI 6GB
      by MrzPdlch
      Hey everyone,

      I just went ahead and unscrewed a faulty GTX 980 TI from Gigabyte. What I found beneath the cooler was, as it seems, a common issue of that card. Two blown fuses on the bottom right corner of the card next to a MOSFET.
      Now my question would be if there is any schematics of that card available to figure out which are the blown components so I can try and replace them together with the mosfet if needed.

      Find some pictures of the actual GPU together with a picture of how it should look like.
      I also wonder whther it might be a problem that there...

      Samsung BN44-00262A H37F1-9SS power supply help finding blown value components!
      by cheeky2
      This Samsung combined power supply and inverter was replaced a while ago from a Samsung 37inch LE37B530P7W TV. However I would like to repair this one.
      I have replaced the Mosfets Q1820 and Q1821 ( FDPF7N50U) which were both blown and the fuse FM802S. The schematic for this power supply that is attached doesn't relate to this power supply as the driving transistors and diodes are D1830, D1831, D1832, D1833, Q1811 & Q1810 are nowhere on the schematic!
      Does anyone know what the components for D1830, D1831, D1832, D1833, Q1811 & Q1810 should be? I ask as I did change the Mosfets...
