    Forcing inverter to start

    Hi guys, i would like to force an inverter to work so i can test CCFLs with it, basically I got a 663l-0623 inverter from a broken TV set that i would like to convert to lamp tester.
    Its a 94V inverter with 24V, GND, ON/OFF, VBR-B, STATUS pins on its main connector. Any idea what pins to pull up/down for it to start.

    Inverter picture: (663l-0623A)



    Basically i was thinking of feeding him +24V and GND but it didn't produce any HV for lamps to work

      I just went through a similar issue, I was trying to replace the inverter in a TV with a generic chinese one. Turns out if I fed 5v to the Von/Off pin then the inverter came on ok.

      I would think that On/Off pin on yours would be the one

          Wellll, things cant be simple in life i suppose, i tried feeding 5V to the ON/OFF pin and inverter didn't turn on, instead when i feed 5V to IC directly than it turned on... Anyhow, Great success!

              You cannot force on the board when the command wires are still connected to the main board since then main board will keep the line LOW (Grounded through the switched Transistors), you have to disconnect the control line from the main board first, and if you jump the pin from STBY pin to the command line pins without the resistor and the connector is still in place then you can damaged the switched Transistor on the main board, ALWAYS use resistor.

                  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...

                  Looking for help with a Viewsonic VP230mb where the backlight comes on only momentarily
                  by lostone
                  Hello, I came here after finding some similar questions asked on other monitors and hope someone here can help me get an ancient Viewsonic VP230mp (23" 4:3 LCD) back to working condition.

                  First a little background, I have a background in computer and electrical engineering, and I'm smart enough to know I know nothing about LCD displays and how they work. For this topic I'm as green as they come.
                  When the display is turned on the viewsonic logo displays in the uppper left for 2 seconds then the screen goes black, the power LED is green (on) and when a computer is connected...

                  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 ...
