I have a Nikada LA1371 that when you power on only has a slight glow of the LCD with no visible image not even the menu screen.
I tried the flashlight test to see if it is simply a backlight issue but that didn't work. Anyone have any thoughts or suggestions ?

Sure it cab be fixed. but first of all do you see your image even without the light as the tube is not glowing? if yes then try to change it with all White LEDs as the white LEDs are available in form of strips now a days. You can uses this to make the LCD glow once applied power to the LEDs they workout cheap and also very less power consumption.
The screen has white glow and no images means that the LCD controller board (part of the LCD panel) is not getting the 5vdc power feeding it from the logic board through the ribbon cable, it is either the cable came lose or dirty contacts, or failed 5V switching transistor for the LCD controller is bad, or blown fuse on the LCD controller board.

Does the lcd screen have a glow to it ? Or is it really dim if u get real close to screen u can see images moving ?
it it has a glow to it you panel lighting is fine but you control board is bad. If you have a dark screen and see faint images you panel back lighting is out u can check the power with a meter at the connection to inverter board on panel.
