lcd screen flickering made in china

I have a nearly new Motorola Moto G 3rd Generation that I dropped and smashed the screen. It was fully functioning, but the front glass was shattered.

I bought a replacement screen / LCD / digitizer assembly from eBay and installed it. Initially, the screen appeared OK, but then started flickering at about 2 - 3 Hz. The screen appeared dull, but that is probably due to the flickering. It now consistently flickers, though is OK for a second or so on power up.

I contacted the seller, who recommended I clean the contacts and try to seat the screen cable again. I"ve tried this a few times but it hasn"t improved things.

I think the important clue might be that the LCD driver board"s OSD is also subject to these interferences, so it actually shouldn"t be the VGA signal that produces (most) of the noise because in that case the OSD should be unaffected as well!? I"ll see about some makeshift shielding (cardboard box+ aluminium foil?) for the board to test this hypothesis. I guess it could still be both the VGA signal and the board itself...

Could be an issue with the LCD driver or it"s PSU as well. If the caps are failing and the power provided is noisy, it"ll act up. The worse the input signal, the worse it gets. So getting the input signal to be as clean as possible is always a good thing (even if there were no other issues) but if a good quality cable is not fully fixing the problem then chances it"s not the only problem you have. Oh and same goes for video cards but if you can get a stable picture on other displays and not this one then obviously it"s the culprit.

I could rule out the PSU by getting a 12v 2a adapter... which I was holding off on because it"s exactly the opposite of what I was trying to do, running the LCD driver board off the PSU
