Can anyone help me with basic T.V. geometry?
Specifically- I'm looking for a good explanation or even a link to a website or post that can clarify what the different service menu controls are and how they work/interact. My direct view CRT has had a problem with bowed horizontal lines for some time now. I know to write down the default values in the service menu so I can bring it back up to original condition, but it seems that I should be able to correct this on my own. I'm happy with my grey scale, so spending several hundred dollars on a professional calibration only for the geometry seems necessary only if I can't fix it myself. I can live with the bowed lines for most sources, but on credits, or shots where there is a fixed horizontal line across the entire picture (think Lawrence of Arabia), it drives me nuts. I'd be happy to spend several hours tweaking it myself with a tape measure, but i need to know what to look for. Any advice? Thanks.
