    Pin out help with ccfl inverter.

    Hello,

    I have a Samsung ccfl inverter that I'm trying to power on without the main board. The ic controller number is Mp1038ey and the motherboard serial number is BN44-00127D. I'VE been trying to figure this out for about 5 months so help would be very much appreciated!

    Re: Pin out help with ccfl inverter.

    Can we see the bottom side of the connector?
    It looks like:
    ADJ = DIM ADJUST
    O/F = BL-ON.

      HANNSG Hi221 -- 2 secs to black feat. CCFL flicker & "burn" marks on power board
      by ttmi100x
      Greetings everyone,


      I have a HANNSG Hi221 monitor that exhibits two seconds to black issues (backlight goes off, display is still on as confirmed by shining a flashlight on it) with some additional oddities...


      The monitor failed on me with a standard "2 seconds to black" some time ago prompting me to initially replace most of the electrolytic capacitors (some of them were bulging/leaking).
      Things kinda sorta worked for a night, then the problem returned along with some flickering and "buzzing" noises.

      Upon closer inspection...

      inverter H tree driver imbalance in an AC inverter
      by eccerr0r
      My cheap crappy 1KW grid tie inverter (GTI) seems to keep blowing IGBTs. When I first got it, it had two failed IGBTs. It used four 60N100's (TO264). I bought 5 from a dubious source (fleabay) and replaced just the two that were dead. The GTI worked for almost two years but recently one of the two that I replaced failed. Since I had three spares, I replaced the dead one. Then a few weeks later it failed again. Weird. Well since I bought dubious China-sourced IGBTs from fleabay it could very well just be a mixture of fakes. I replaced it, but then a day later it failed again! I put in the last...

      Vizio E55-E1 bad backlights or bad inverter?
      by x_orange90_x
      I just got this tv today and it appeared to have no backlight on. After taking off the rear cover and checking again in the dark I can see that MAYBE one quadrant is lit.. But still it's quite dim. I was going to check the LEDs with my tester, and I found LED 1 and LED 2 + pins on the wire from the inverter, but I couldn't identify a ground. Nonetheless I tried using a mounting screw on the inverter board and also the chassis as ground but regardless my tester reads 300 which is what it reads when there is no voltage draw.

      I don't know how exactly to test the inverter itself. Is it...

      APSINT3636VR 3600W APS INT Series 36V DC 230V AC Inverter/Charger schematic
      by Gentian
      I have a tripp-lite aspint 3636vr inverter charger which blow some of mosfet transistors. I replaced them repaired also the driver circuit and tested but the mosfets burn again.

      It work very well as inverter and also as charger if I let the rear switch in auto mode (inverter) and charger only(charging) but in auto when I connect the feed line 220V AC first time it pass ok to line and start charging the batteries but when I remove the feed line it pass to inverter mode and if I do it again the second time when passing from charging to inverter the Main transformer start making a...

      Insignia NS-LCD19-09 (PS OK, Inverter problem?)
      by valvashon
      For some reason I'm just not going to let this 19" TV defeat me. I guess because I have a schematic to work from I feel like I'm oh so close.

      History- while adding a turn-on circuit I let a small screw roll under the power board. Worked through all of that circuitry, probably replacing a MOSFET and PWM controller that were not bad but I was following the service manual. Finally figured out that the power supply is in working order when the inverter section (for the backlights) is disconnected. When the +12 supply to the inverter is disconnected the +12 and +5 will come up...
