I looked at a similar board over and I see several places that are labeled fuses but I'll be damned if I can tell where they are, I know some will have a label but just not be included in a particular design.
ok, if you are sure you are getting a new mainboard, something you can try if that there is a cap and not a fuse, is just remove it with a soldering iron and try the tv, I have seen this work, that is removing a shorted cap and tv working with it removed.
This is everything related to the panel, backlight (leds), led driver, power led driver...
There is a problem with the panel or with the T-con, then the error would be "5".
I think it’s backlight related. Unplug the blue tabbed cable from the main board and plug the tv in. It will do a backlight test and if it the leds are good the leds will stay lit
