The lcd monitor has back panel illumination. It appears the segments in the bottom left corner went out. It is only slightly visible because of the surrounding light. Unfortunately there is no quick or inexpensive fix. Looks like a replacement monitor is the only solution. Lcd monitors have a shelf life like any TV monitor. I would call JJP and ask the cost for a replacement monitor. I'm sure it will be very expensive going through them but at least you know it will be plug and play. You could take a measurement of the back monitor and look on best buy or other online retailers sites for a replacement. Go to specifications and check the measurements to see if it will fit your game. Sorry I do not have better news. If you just bought the game the previous owner could have known about this issue. Perhaps he will split the cost with you. If you bought it recently I'm sure this game was not cheap. Good luck hope all works out. It's a great game.
