Have been working on this set off and on for about 2 months. After it came in stuck on standby I decided to immediately jump the power supply bypassing the mainboard. All voltages checked are spot on. However I noticed that the backlights would not turn on and if you were lucky you might get a sputter from one or more of the bulbs. Just to be sure I ordered more inverters from China as the originals were out of the 3 percent tolerance. Got the inverters and put them in finding 2 bad bulbs in the lower quadrant of the screen. I found this by using Bud's Cfl method. Have progressed to this point but cannot get the backlights to stay on even with all new cfl bulbs soldered to the inverters. Even tried to simulate the dim control with an AA battery to no avail. I will worry about the mainboard signals after I can get the backlights to stay on. Will definitely need some help on this. Thanks.
