I need to change my Note 4 as the touch is getting progressively more temperamental. I did look into regenerating OLED panelswith screen burn using recent discovery of molecule sensitivity in 593 and 1064nm (IR) direct laser scanning when in “black” mode *#0*# but the problem here is that you need the board connected for it to work and it takes weeks.

Intriguingly this also helps explain how the compensation cycles work on newer phones/TVs and why negative images sometimes appear for a while then go away as its the controller averaging out over many many frames.

Would this fix a bad charging situation? it worked before, won’t go over 3%, not the battery as checked this (and other things like connectors, etc). Also black screen can be bad backlight or (worse) motherboard fuse. I did find out that sometimes the screens are rejects and have good screen/touch but other problems.

I’ll just have to hope it isn’t the U2 or tiny missing SMD near the battery connector.

Hi, I found that a lot of the "bad" screens are fine but its the e2prom which is hosed.

Typically this happens when someone swaps out the cracked screen and does not do the two critical (that I discovered) modifications.

If anyone wants to know how email or tweet me, I am @darnstadium

Hi, similar problem here. It might benefit others to know that some phones are very fussy about the EM permeability of the touch screen; the reason for low signal could be that simple. I am working on a Z and using my idea would allow a screen replacement to be graded without ever opening the box so if substandard could be sent back unopened (most sellers refuse to refund if screen is used at all) the same method can also be verifiably used to evaluate non OEM batteries and compare to the original to see if they are genuine new, genuine used or counterfeit.
