Please check LCD connector. If doesn't help you should flash complet ROM with SPFT and firmware upgrade option.You can test colours in testing mode, open calling dialer and type in *#*#33#*#*

Otherwise please talk to seller.

Please connect old screen and check.
If fault still existing, please disconnect battery and screen from motherboard for minimum one day. But I am still strongly recommending flash from full ROM with SPFT and firmware upgrade option.
