Just picked up this 30 inch Samsung HDCRT (TXN3075WHF) for 25 bucks on Craigslist. I'm upgrading from a generic 17 inch JVC and thrilled to have component hookups now. Two things though, the TV makes a nasty buzzing for about 90 seconds after powering on but then goes away. Second, is there a way to adjust the screen size at all? In 16:9 mode on the Wii it is overscanning and my autism is having a hard time not having everyone on the screen the way it should be as it would be in 4:3. Doing a grid test with 240p suite the alignment is kind of fucked up but there are no menu options to fix this (unless there are options in a service mode menu?).
