    Digitrex CTF4071A

    I got this tv that wont come on, it has a red power led. When I took the cover off I checked fuses and noticed a fuse blown on the inverter board. I took out the board and found a scorch mark under a ic "ao6614n??" its a n and p channel fet package. looked up the datasheet to get the pin-out and both diodes were shorted. I found the same chip on another inverter board and swapped them over, changed the fuse. Crossed my fingers, switched on the power but it still wont turn on. I got a 5v supply but only 4.78v on the stby of the power supply.
    I'm thinking that this set might of had a power surge or something.
    Any ideas peeps

      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,...
