Re: T240 Monitor Backlighting Issue
So the backlights did come on for seconds and then black out? Then it may be bad lamps, bad MOSFET (the SMD with 5 legs on the bottom and big tab on top), bad inverter power supply section, bad BL_ON signal, ETC.
Can we see staright shot pictures of the top and bottom side of this Power supply-inverter board. It may be time to make two test lamps.
