Default Zen 8GB Display Brightness Issue

I saw a similar problem posted here with no solution so I thought I'd see if anything has come of it.

I dropped my Zen and the screen broke. I'm not sure how, because there was absolutely NO physical damage on the housing, but it broke. The screen still worked properly in regards to background brightness though. It went bright when using the controls and faded to dim when not using the controls. So I bought a new LCD for it and it and installed it myself. However, when I fired it up the display brightness wasn't 100%. I set the display brightness to 100% and it didn't change. BUT when I set it to 10%, the display got brighter. You can see it tries to go to full brightness when it's time to do so. The display flashes brighter for 1/2 a second and then stays dim. But when it's plugged into the PC, the display brightness works like it should. Also, when I plug the USB cable only partially in so that the plug-in shows up in the battery icon (but it's not connected to the PC), it works properly as well. So I thought maybe it was a battery issue. I hooked up a variable 20A power supply and set the voltage to 3.7V and slowly worked it up to 4V (with the battery disconnected) and still nothing. I thought maybe I had a faulty display, so I hooked up the old one. And it had the same issue even though the brightness worked before I took the player apart. I've tried EVERY firmware upgrade and downgrade that I could find and still nothing. Anyone know of any solutions to this? It would be greatly appreciated.
