How can I tell if an LCD inverter board is bad? Can I hook up direct power to the LCD panel to ensure that it's working fine (backlight). I just had someone purchase a used LCD that was guarenteed in good working condition to fix their problem with a dim display (because I was told it was a backlight issues and the backlight needed to be replaced). I wasn't about to try changing out a backlight. Needless to say, after putting in the new display, I get the same results.
My brother-in-law has some cold cathode ray tubes in his computer, can I use one of the inverters from those to test the backlight and see if it's the inverter? If the backlight works, how can I test to see if the inverter is even getting any juice?
