You need to check first the power supply board whether the output supply 12-24vdc for the inverter board is stable and not flactuating..you can measure the output voltage with a multitester..you get a voltage output of 12-24 with the inverter board is connected or loaded to the system.be carefull of the high voltage at the inverter board..once the output is stable replace the inverter board or you can measure the output of the inverter be very carefull..the output range upto 500vac.be carefull..if the high voltage is stable replace the lamps...tnx and good luck..

My screen is flickering on and off on Vizio LCD TV? I was wondering if it was the main board or the T-Con board.


Flickering can be either with the fault to its back-light inverter or with its main power supply regulator board.

GV42L FHDTV10A CCFL & Inverter Board issue


Is the strobe light affect the entire screen? or just a part of the screen? I would say you either have a problem with the inverter circuit or power supply. You need to ensure that the inverters are being fed a clean 24vdc. If you are getting ripple voltages in the 24vdc power supply, your backlights will flicker. Also check the inverter boards and also the power supply capacitors for any bulging tops. I would also suggest you monitor the "backlight on" signal from the main board. It should be around 3.3 Vdc and again no ripple.

WE BOUGHT A VIZIO GV42L HDTV IN FEB.2007 AND IT JUST RECENTLY WONT TURN ON.THE "VIZIO" LIGHT IN FRONT OF THE TV TURNS ON BUT NOTHING ELSE.


The power supply may have failed, or it is in the safety shutdown mode due to short circuits in the power supply or in the backlight inverter board, you can try disconnecting the power cables to the backlight inverter board to see if you can get the TV to come on with sound but will not have picture.

FLICKERING BACK LIGHT


Sounds like you have an LCD tv with backlight problems. Check power board for domed capacitors and replace them. next check connections on the inverter boards. they are on the sides or just one side. Becareful there is high voltage output from these boards. If the cable from inverter board is not good to the screen you can get a strobing. the inverter boards may need replaced. or cales to screen may be bad. The panel also could be bad.

Vizio television screen flickers like a strobe light


lcd sets use florescent tubes to light the display and, a ballast to power the tubes just like the lights in an office ceiling.
the tubes are called cold cathodes and, the ballasts are called inverter boards. replace your inverter circuit board it connects by wires to the cold cathodes so; isn't hard to find.
