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!!

It may be in safety shut down mode due to shorted circuits or power supply failure due to such thing as bad DC filter caps. You will need to do in-depth troubleshooting.
See www.shopjimmy.com if he has the picture of the boards.
