First, this is going to need a new display assembly. If that doesn't work, then it's the motherboard in the phone, or simply a defective replacement. Get another one if this is the case to confirm.

Should this be the motherboard, don't bother fixing it. The boards cost more then a phone and you have to be careful, since some of them are IMEI/ESN blocked. You can't verify a lot of these, since some sellers don't know or evade the question for obvious reason. I wouldn't bother.

They can also cost more then the phone is worth at times.

You need to know compoent level soldering, whicj is that tough

yup i will try with that . otherwise last option is to replace the logic board

like I said, you need to compare the cost and find the best deal, DO NOT buy used boards due to the IMEI block risk, only time you do is if you get a cracked 4 on craigslist and it is not stolen, and the IMEI is clean and checkable
