[Q] G1 broken display problem - bad colours

Hello
I purchased G1 with broken display on eBay from other user, hoping I could fix it.
G1 works good, its rooted and running cyanogen rom. Digitizer works, display is readable but colors are upside down. For example in settings screen text is yellow, background is blue arrows are somewhat gold. App menu background is black text, blue, attached pictures should tell more, one is home screen and other one is flashlight app with half intensity.
I dissembled the phone, searching for any signs of damage or anything, everything seemed ok. I am not sure if I should buy new LCD screen or Flex Cable. Did anyone encountered similar problem?

[Q] Background ghosting

I have had my nexus 7 for around 3 months now and have noticed that there appears to be a frozen image of the white elements of my home scree that are slightly but permanently visible. It is quite faint but I have noticed that things like the digital clock, and the white notifications are always visible. Sometimes even with the chrome Web browser get stuck being visible on the home scree. Is this a problem that others have and is there a way to fix this?
Thanks
does it appear while taking a screenshot? if not, its the pixels burnt into the display if you left the screen on the same picture for too long.

[Q] Line Across Screen Of Inverted Pixels

Got this Nexus 7 as a gift yesterday from a relative who received it from their employer. Since hes a roughneck in the oil industry he doesn't really have time to play with fancy tech toys so I got a nice toy to play with myself.
There was an odd issue since the first time I turned the tablet on. There is one line of stuck or what I'd like to call inverted pixels right above the home bar on the device between the bar itself and the remainder of the display on the screen. Its like its separated by one line of pixels. If I rotate the device the line stays in its original position. I call these pixels inverted as they are black when the screen is white and white when the screen is black for example. Tried a couple of those stuck pixel apps. No dice.
Any ideas?

True Blacks are Grey (ish)

Hi guys,
I have noticed in the dark when using my note 3 in the settings menu the bottom portion of my screen seems to be grey not black. At first I thought maybe this was a software issue so I took a screen shot and zoomed in. When viewing the photo zoomed in the entire screen is grey ish with lines (normal lines had on all amoled screens) When moving the image the greyness does not move which to me says its the screen. However! When using a pixel tester and putting a pure black picture up the screen is perfectly black.
Ideas or thoughts?

That's the way Touchwiz and Gingerbread was originally designed and Samsung kept it this way. This is completely normal and is the software. It's not an issue. It is the same way on my Note 3,Note 2 and Galaxy S II.
