    LCD LG (LGP32-08H) repair

    ok i own this 32 inch lg
    after 10 years of use it just turned off
    after inspecting the pcb i found a bulged cap
    replaced it,but i still get no lights on the inverter
    while i put the flash on the screen i see an image
    after inspecting the 24v thats supposed to go on the inverter i only get 13
    and weird thing is that on the other side (that controls the mainboard voltage)
    i should get a 12 volt (which i read 7)
    and 16.5 volt (which i read 8)
    and its weird because it seems to function fine (because i get image)
    so what should i do about the inverter?
    and where should i look next?
    thanks in advance

      Please upload good clear pictures of the whole backside of the TV showing all the boards and then the pictures of the whole top and bottom side of the power supply board.
      What does your meter show when you test the Voltage of the 1.5V battery?

          i also checked the inverter pcb,it only has 2 caps on it which seems fine and all the other elements,btw when i turn the tv on a blue led lights up on the inverter board and it fades off soon

              12/24 volt compressor cooler box inverter capacitor failure
              by sam_sam_sam
              This is my son’s cooler for his semi truck for his drinks the other day it started short cycling ( running for a second or two then shutting down ) and restarting four or five times then going into an error power cycle the controller then it would do the same thing again

              Found a 47uf@63 volts double the ESR value of a new one
              The 220uf@16 volts same as a new but 220uf@35 volt replacement capacitor

              The main filtering capacitor was not replaced because I did not have that was not too tall

              Where the 220uf capacitor is some type of switching power...

              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...

              external hd Seagate, broken down the +12 volt and USB 3.0 SATA board
              by gabri2211
              Hi to all 😎
              I'm looking for any useful information to repair this interface (I have attached the image).
              On this board I read E3215-1215A_4D.
              This is the small plate inside the HD enclosure that allows to connect a 12 volt power supply, interface the disk with a USB 3.0 socket and is connected to the HD with the SATA connector.

              If any of you have found a burnt or short-circuited component in a circuit like mine​, if you have useful diagrams for the repair, or even better a description for the tests at the test points, I would be very grateful.
              in particular...
