    Sylvania LC220SS1 bad inverter

    Hi, my tv Sylvania LC220SS1 had standby red light on when try to turn it on
    the green light blinks 21 times and then the red stanby light.I replaced the
    power supply that also has the backlight inverter and the tv works normal.
    I want to know if somebody can guide me to repair the board if it is possible.
    I am not expert technician but I have repaired some tvs as a hobby.
    Thanks for any help.

      HV Transformers could be bad or the Inverter IC/circuitry....Most time with these TVs is if you can get a replacement board, say thank you and replace it. To repair a Uni-bd like that would be very frustrating and time consuming from my experience and to top it all off you say you are no expert. The thread will get very long and time WILL be wasted. Good luck on your replacement Bd.

          Thanks for your answer.I just wanted to know if there was an easy way to fix it
          but now I know its not that easy.

              For future reference:

              By the looks of the rusting RF section, this TV has been probably out in the trash and moisture definitely got to it for a while. Dont bother. Once you see rust or oxidation

                  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...

                  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 ...

                  Sony KDL-46BX450 Inverter Troubleshoot Logic
                  by caseyjay_48
                  I am currently on a troubleshoot of 46” Sony KDL-46BX450 tv. I came back from Washington to Texas on medical emergency and had to leave all my tools up there. All I have is a couple of screwdrivers and a dvm. I wish to ask the community a troubleshooting question. Please forgive stupid questions as meds I am taking produce brain fog.
                  I have well maintained Sony KDL-46BX450. It went black one day. After turn-on, I get solid green light and Sony logo in screen center for about 1-2 seconds, then black. No blinking LEDs, no hissing. Flashlight test shows screen characters dimly viewable,...
