Attention again even if an external monitor, the problem does not appear, it may still come from your graphics card.
Screen dark without light, in general it comes from the inverter and in very rare cases of the motherboard, but it can also come from the neon of the screen.
Color screen (Red in general) so this comes on the screen but sometimes the graphics card.
