@letserherrera that is most likely a panel error. There is of course the slight possibility that this is caused by a overheating GPU on your main board but the way the picture fades, it's most common of a panel error. It is most likely a loss from teh LCD driver boards. You could try a Tape_off and see if that changes anything. Let's try something first. Remove the back panel. Then with the TV unplugged, remove one of the ribbon cables from the LCD driver boards. Now try and turn your TV on. Note exactly what your TV does. Then unplug the TV and reconnect the ribbon. Next disconnect the other ribbon, plug your TV in and restart. Let us know what you get with this.
