problem with the monitor Display cable. it is damaged.
Normally monitor will receive 3 colors red, green, Blue signals from CPU. If one cable i.e Red wire connection is missing in display cable which is connected to monitor, Red color image on monitor wil be replaced with other fade color.
So, need the replace the display cable or display connector!
in 15pin connector of the monitor, red wire goes to pin No:1 green wire goes to pin no:2 blue wire goes to pin no:3 yellow wire goes to pin no:13 white wire goes to pin no:14 and black wire goes to 5&15. Now display will come!
