Screen streaks. Anyone recognize it?

[Smelter]

The left hand half of my Nexus 7 held vertically has white streaks horizontal to lighter (especially text) areas.
The weather here has been exceptional for our area with temperatures in the high 20's. Don't laugh this is the north of England.
I could have sworn that it had 2 years warranty bought from Google Play, but they claim it has expired.
Can anyone pin down the problem hardware-wise so I can replace the right part.

Thanks in anticipation.

P.S. Photo won't upload. It is small enough but I get a server full error. I'll try again later.

Well I found someone with a similar problem here :-

but I am still no nearer knowing whether to replace the screen.
Any suggestions?

Well I am getting a bit closer. I have discovered that there is a way to do a screen grab and the resulting picture is error free which suggests that the screen memory is intact, so the streaking is purely in the glass. Looks like it might be a hardware failure/issue after all.

Well the screen problem just keeps getting worse. If I use the tablet in landscape format for a while, when I turn it back to portrait I can see a screen burn image in the streak area. So I have bitten the bullet and ordered a replacement screen. Good job their are teardown videos to hold my hand.

It could also be a bad connection? Try reseating the screen ribbon connector. Refer to ifixit teardown.

If its just a single line of pixels that are stuck there's an app that might fix it, or not.

[Q] Bad screen or damaged flex cable?

I was waiting to see a screenshot or better description. With the Tapatalk pro app I no longer have size restrictions on pics. The web host is limited with no way to completely delete old uploads and annoying pop_up ads.
