Digitizer Replaced, Screen blinking

I replaced the digitizer and screen on my iPhone 4, it worked fine for 24 hours. Then the screen went blank, I could tell that the LCD was working, but no video. I took the phone apart to check all connections. Everything seemed fine, I reseated all the cables. Now it works, but blinks randomly. Any thoughts?

Hi, Sorry to be the bearer of bad news but it seems to me like there is a possible display issue (Obviously) If you can check on the board or on the display module cable you might see that one of the connector plate if not a few may be ever so slightly damaged. Check along the ribbon and look for snags or possible breaks too.

I checked it out and there is an ever so slight tear on the cable. Oh well, maybe Santa will deliver me a new one on New Years'.
