The power supply is not latching. This is common on those machines when they have bad capacitors. You can change the whole power supply out if you are versed in electronic disassembly.

It sounds like you have a power supply problem, this powers the inverter! Where you just replaced the inverter, we could assume it is good! Look for some bad caps (capacitors) on the power supply board. They will look bulged on the top an may be a little leaky (brownish stain). The power supply can fail on some output and be good on others. Was the back light inverter new? If all else fails, see if you can return the back light inverter and get another! I hope this is helpful!!

If your Tv is in warranty or you have a cover plan, you need to return the Tv for repair or replacement.Your Tv sounds like it has a power supply fault.

Check the lamps connectors on the backlight inverter board make sure they are not loose. You may be ahving failing inverter board itself.
