Customer brought in this dead Sony. I narrowed it down to a bad main. After replacing it, the front LED power light was flashing red and Green. When it stayed red, I turned it on and have no BL's but do have the music loop that will go up and down with remote but no BL's or osd.The power light is white but no picture. Why no BL's? And when I powered it off, there is no power light on the front.

Do you have picture but no BL? Did you take flashlight to screen when you hear the sound and turn it on? -
Does TCON have a direct connection with a backlight driver? If yes remember that MB must be paired to TCON..Comment

I tried the flashlight test but did not see any video. How can the main be paired to the TCON if you can't see the screen?Comment
-
Did you do an update with usb after changing main board?
it’s required most of the time to pair the tcon and main board.Comment

you can try this..
Download upgrade, rename it in same folder as "upgrade_loader.pkg", put it in pendrive and then in tv, plugging the power in when keep pressing ON button on the tv
brings to a state with blue led steady in standby position, releasing the button and pressing it again brings to a pulsating white led, wait pendrive led to stop after few
pulses, removed power, reinsert it, white led does 3 - pause - 7 pulses, then turn it on with normal key, tv turns on with backlight an maybe an image..Comment

I have a Lithonia Lighting 65-Watt Gray Hardwired Compact Fluorescent
I also have back when Light of America had these light bulbs available for yard lights
