    Westinghouse W3213 no backlights

    Very simple fix, fuse F5 (for the PWM IC) on the inverter board.
    The TV does have all the voltages but no backlights.
    Caps in the power supply should be replaced at the same time as well.

      the notorious Darfon boards!
      have succeeded many times in replacing the transformers (4003L, 4006A etc).
      cheers!

          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...

          Samsung UE48H6410 replaced Mainboard but backlights doesnt go on
          by max789
          Hello, I have a problem with my Samsung UE48H6410SSXZG with the main board BN41-02156A and the power board BN44-00709A. Everything seemed like this, the TV could no longer be switched on, the standby LED always flashed 5x2 times. Backlight was off and no sound from TV. Also made the flashlight test and there was no picture.

          I made the following tests:
          1. Disconnected the main board from Power Board = backlight works.
          2. Connected the main board and disconnected the T-Con = backlights does not work.

          So I ordered a main board from Ebay also BN41-02156A but from...

          VIZIO M557-G0: Backlights or ???
          by bpcannan
          'Morning,
          I get sound and picture when powering on the TV and its stays that EXCEPT that the left half of the screen will dim every few seconds then return to normal while the right side of the screen performs as designed.

          Did the soft and hard reset options pulling the plug, using the reet option in the vizio menu to no avail.

          I checked the mainboard - found some popped capacitors so replaced it - but that did not change the situation.

          I checked the t-con board. It is getting good power. Then I removed one ribbon cable to see if I could isolate...
