Respuesta a "No backlight, tried inverter, what now?"Hi to everybody! I had the same problem that you described: backlight on only for 1 sec when using the F1 and F2 keys. sometimes 30sec on, and then off. I tried to: -change the inverter- Nothing changed -change the inverter cable- Nothing changed I CHANGED THE LCD LAMP and now it's working fine! So the problem was just the LAMP.
