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 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.
