I have a Sony camcorder that has an issue with the LCD screen..it has a bluish tint to the pictures, and can only be seen when the screen is tilted at certain specific angles. But the touch screen is working fine. I believe the problem started off after a holiday and there was snow..perhaps some moisture. The problem should be with the screen cos the viewfinder shows that the image is normal.

I'm thinking of repairing myself by buying some replacement parts, but not sure which is the part that is spoilt (ribbon cable, LCD screen itself?). Any comments which part it may be based on the situation? Thanks
