Red tint on Hantarex Polo

[comatsu]

After working well for a while, my polo is now displaying everything with a harsh red tint (for example all yellows show as orange).
Could this be something that can be fixed by adjusting the red cutoff, or is it some other problem?

If it can be adjusted, where is the red cutoff on the polo 25", as I cant seem to find it.

red cut off is on neck card but polo suffered leaky colour drive transistors so its most likely that

If its a drive transistor issue how can it be fixed?

you replace it,it's T2 on the neck card(bf859 is the transistor part number)
