    HP DV5-1000US inverter or lcd

    Hello everyone.

    I need you value opinion on this.
    I have a dv5-1000 hp laptop with no backlight.

    My first was checking the inverter with my multimeter on ac mode
    suppose this need to generate some kind induction (voltage go up liitle bit), but, this doesn't work.
    So i bought used inverter but still nothing. (as023216300)
    i bought a second one , new, but still nothing.
    The second come in with different part number as0231701f3).

    The lcd backlight was tested in is good condition.
    The voltages come in into inverter are.
    1. 19.03v
    2. 14.25v
    3. 0.13v
    4. 16.17v

    two pictures are include.
    1. Lcd testing
    2. Screen very dim image

    any ideas.
    Thanks.

      19v to run the ccfl but 3v are missing on your inverter.without 3von off inverter can not starts

          From where can get the 3volts?

              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...

              A modified sine wave inverter + a grid tie inverter?
              by eccerr0r
              If I had a solar fed grid tie inverter (GTI), a modified sine wave inverter, and a power outage occurred, what would happen if you disconnected mains, backfed the modified sinewave inverter (MSI) into house power, and hooked up the GTI to the output of the MSI, would it work?

              Next thing is trying to charge the batteries using solar power, but that's another issue ...

              Sony KDL-46BX450 Inverter Troubleshoot Logic
              by caseyjay_48
              I am currently on a troubleshoot of 46” Sony KDL-46BX450 tv. I came back from Washington to Texas on medical emergency and had to leave all my tools up there. All I have is a couple of screwdrivers and a dvm. I wish to ask the community a troubleshooting question. Please forgive stupid questions as meds I am taking produce brain fog.
              I have well maintained Sony KDL-46BX450. It went black one day. After turn-on, I get solid green light and Sony logo in screen center for about 1-2 seconds, then black. No blinking LEDs, no hissing. Flashlight test shows screen characters dimly viewable,...
