I recently bought a Panasonic CT27D12D and it seems to be a great regular tube (3-line digital filter looks great, and for $300 it was a good value). However, I have found two things that are quite annoying to me. I'm not sure if this is normal with tube tvs because my previous set was a Sony Wega. 1. The corners of the screen (very noticeable if the screen is pure white) are darkened. For some reason the upper right is a tan color while the other corners are black. It's not noticeable unless the screen is mostly white but it is always there I can tell. Not sure if I'm describing this well enough... sorry. 2. The set emits a buzz that overcomes the volume when watching TV. When using the component and s-video inputs I don't notice the buzz (it may still exist... I'll check that now). Thanks in advance for any help.
