Ming , the 2 Norcent I have worked on were in fact made by LG.
Hoping yours is also made by LG.
If you have a bright display it is sign that the neons are on, thus the ballast is ok.

you don't have pic but do you have OSD ??

no. picture, no any display but only the bright screen, with not thing on it.

You probably have a bad LCD Drive circuit board. Try unplugging the LVDS
cable while watching the screen. If no change, your LCD Drive (sometimes
called T-Con) circuit is bad. Many manufacturer's only supply this as part
of the LCD Panel Assembly. I don't know specifics about Norcent, as I have
not worked on their TVs, but I work on a lot of LCD TVs in general, and this
has proven to be a reliable troubleshooting technique for me.

You may have a defective inverter board try checking 24volt line going to
that panel also your power supply might not be fully operational
