    Sylvania LC320SLX shutsdown quick

    This tv shutsdown to standby so fast the B/L wont flash nothing. I'm not familiar with this chassis. I checked mosfets on inverter and the 4 xformers are ok on the secondary. If I pull all the wires off the inverter and power up it stays green. IDK, I think I attached pics will see if they show up... Referring to pulling the wires I mean the ribbon going from main to inverter.

      I appreciate the pictures. This is an unusual design; I don't think I've ever seen anything like it. What I find most remarkable is the 'inverter' seems to be unusually complicated. Of course, it's got it's own power supply. But where is that ribbon cable at the bottom of the inverter going?

          Hi Bill, there is no per say T CON board on this tv. that ribbon you speak of goes to the screen as well as 1 from the hdmi to the right side.

                  I have the same tv here for repair,but there is no power at all. no 3.3 or 5volts. not sure were it comes from. anyone have a schematic on this LC 320SL ?
                  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...

                      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...

                      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 ...
