Hi there, I'm Tim and will be assisting you today. I have over 15 Years as an Engineer and have been with eBay, DoD and many others. I will do my VERY BEST to help you. If you like i can offer remote access and a call. In addition, with any positive rating I will support your question going forward for free.
These are pretty easy to diagnose, if the screen looks off to you and looks fine to me after i Remote in, we know its a hardware issue, if i remote in and i also see same tint, its software. Both will have different paths top resolve. I will need remote access to do this. Let me know when you are available.
