Re: 42LG50 no backlight
The black fuse was the issue. I studied this TV for a couple of weeks off and on overlooking that fuse. The voltage measurements going in and out of the master inverter was not enough for me to diagnose the problem area. I did replace the inverter caps as well and ended up using a pico axial fuse soldered carefully. It is still working great.

Re: 42LG50 no backlight
Having no schematics for inverter boards tends to flat-line my learning curve on LCD TVs. This forum helps so much to keep me enthusiastic while trouble shooting.Leave a comment:

Re: 42LG50 no backlight
Be sure to check the fuse that member rb0746 posted on the first page. I have a bad fuse on the master inverter as he described. I replaced the fuse and the TV works. Time will tell. All my voltages seemed correct but I had missed the fuse .75A/76V fuse F1 color black not white....Leave a comment:
