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.

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..

Hi,connect the tv to a stablizer..dont connect it direct from power source and make sure you place it in a place where enough air can reach it.
