    FN155 replacement

    Hi all, i have this toshiba tv that uses this transistor on the power supply. Its function is to feed the supply voltage to the STRF6268. I cannot get any clear info on it. Its apparently used in a Sony KV2167MT.

      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...

      Desoldering gun station modified to use a 18 volt @ 20 amp switching power supply
      by sam_sam_sam
      I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump

      One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy...

      Samsung pn59d530a3f no picture after power supply replacement
      by Goldenmonkey
      My samsung plasma pn59d530a3f recently had a loud pop and stopped working. after opening it up, I found a blown resistor and capacitor on the power supply board. The circuit board was damaged where the resistor connects so I opted to buy a replacement board.

      after installing the replacement power supply, the tv powers up but has no picture. The electronics store I bought the power supply from said the next likely culprit could be the Y Main board.

      Is there a way to test the Y Main board before just buying a replacement? Or if there are other areas I should check?

      Modification to a ZD-987 desoldering/soldering station using a external switching power supply
      by sam_sam_sam
      I have been working on this concept for quite some time now with limited success but recently I found a switching power supply that is setup for the voltage that this soldering station needs to operate at however it also needs part of the secondary circuit from the original switching power because you need several voltage rails

      I once tried to get a ZD-915 desoldering station to work on a 18 volt battery power supply but unfortunately things did not go well but I did find a work around but I might try this idea again but going at a little differently more about this another time...

      Dell 2209WA - power supply - Fusible Resistor replacement
      by jinu_j
      Hi

      I am trying to repair an ancient Dell 2209WA Monitor which suddenly shut off with a pop sound. On investigation found that one of the fusible resistors had blown. Further investigation identified multiple components as faulty because of which the fusible resistor blew. Please refer the attached circuit diagram showing the components that were found to be damaged.

      1. FR950 - blown fusible resistor - 0.2 Ohm 1W
      2. Q950 - shorted Q950 MOSFET - 650V 10A N Channel Mosfet
      3. R835 - Blown Resistor - 20KOhm SMD resistor
      4. D930 - Shorted Schottkey Diode...
