Thanks, good to know....

Re: Sharp LC-50LB370U PS or backlights?

Ended up removing the screen and checking the LEDs. There were a few out and a one in poor illumination compared to the rest. Turned it on to test the voltages with the screen off and getting 7 blinks, assuming that is because the screen is disconnected. Also, now no voltage on the LED connecter - side pin 4 and 9. New LEDs on order. Hopefully the 7 blinks I now have will go away with reassembly.

Hello all. Working on a sharp LC-50LB370U. A few days ago, I turned the tv on and immediately left the room, came back in and tv was black. Turned it off then on and all good (didnt think much of it at the time) for about a week. Did the same thing again but stayed black this time. When turning on, the word "sharp" is dimmer than normal I think then tv goes black. I do have sound and do have a display with the flashlight test. I trided unplugging and also holding in the power button for 30 sec, no change. I opened the back up and the backlights do turn on to some extent for a moment...
