Screen Noise
« on: May 08, 2005, 02:49:55 pm »
When ever i run an app in magnified mode (like opie programs) i get a high pitched buzz.  Everything wokrs, and it has done it from day one.  I tried reflashing, thinking that it might help but it did not.  I am using the stock sharp rom, but i have tried the gpe rom and it had no trouble but I didnt see a way to change an apps resolution in it.  


Any ideas?

Thanks
Todd

Mine does the same thing.  Only in magnified mode.

Mine too... only when running apps in magnified mode (which I've only done to test this).  Though I can only hear the noise when I have the Z screen close to my ear, which I don't often do  

Now if someone could make a Z screen sound like a sea shell, that'd be cool

Besides the 5x00 series the Zs use fluorescent light.  The noise is probably the ballast, but I don't understand what about magnified mode would make it louder.

That noise probably comes from the DC-DC converter which is used to power LCD. I guess this should be harmless if no of extra heat produced.
