Toshiba Satellite P25-S5092-display problems

Question

My screen on the left has a bright pink color all the time-approx. 2 inches wide. Could you tell me what causes this and can it be fixed? My laptop is almost 5 years old. Also, at certain times my fan on the bottom is very loud and I have to shake or move the laptop around to get it to stop, any suggestions on how to fix this.Thank you,Victoria
