    Re: FLX-3202 Element made by poloroid

    I think the video board is bad too. Dunno how or where. The only other time I saw this type of thing was with a bad video board. I seem to get mostly hard-to-fix flat panel TVs... And I can't find the video board for this one.

        I had an flm32 polaroid with the same problem and it was not the inverter board to my surprize.
        I found the whole module on ebay for 22 dollars (working).
        I never had a chance to find out what really happened because I sold it as soon as I repaired it. (still works)
        I blamed it on the main board. The inverter board stays with the panel so I knew that was not the trouble.

        I did not try the flashlight test and I should have.

            I found a completely blown bad cap on the HD TV tuner board. Replaced it, but no difference; with the board in or out, the TV does the same thing. Removed the other tuner board and same thing. Also, I am fairly certain, due to the noise that was coming out of the transformers, that the inverter board is bad, because I have heard the same noise once before on an inverter circuit that tested fine but would fail after a few minutes. Drove me crazy figuring it out. It was part of the psu. Replaced it and that tv still works.

            I'm going to do the FL test now.

                Look for burnt/leaky ballast caps as shown here if it has the same LCD panel:

                    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...

                    Gigabyte H610M S2H V2 help to identify the element.
                    by flysky
                    There is a motherboard Gigabyte H610M S2H V2 (DDR5), I can't find boardview
                    Help to identify the element, marking on the element - C31PH. It stands next to the USB 3.0 and it looks like it is ESD Protect chip. We need a datasheet to this element. Maybe someone has already identified such an element. Help please.​

                    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...

                    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...
