    Sharp LC-32DH65S

    Sharp LC-32DH65S does not power on inverter (or fails to get it on)
    Owner reports it has taken longer and longer time to get it on.
    So, bad CCFL's or inverter? Looking for common stuff on these.

      Sharp Aquos LC-46E77UN inverter testing

      I picked this TV out of a trash pile. When I plug it in I can hear the relay on the power supply “click” almost immediately, and then 7 seconds later there is another “click” and the power/OPC LEDs start to flash: two pulses on the power LED, one on the OPC LED. I didn't notice any sign of life from the backlight, but more on that below.....

      The service manual () says this is a “DET_10V error: UR10V or A9V is not applied”, but after checking several voltages I believe the power unit is tripping off due to an overload as soon as the backlight tries to come on; this kills...

      Sharp LC-60LE633U Inverter output voltages
      by organman
      Greetings, I have a Sharp LC-60LE633U when powered up only the V light comes on. I have checked the LED strips and they all light up. When the LED's are plugged into the PS board I get an output voltage of 74v DC. If I unplug the LED's the output voltage on the PS is 184v DC. Does this indicate a weak PS?
      Thanks...

      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...
