apologies for the lack of knowledge, but, what are we looking for here?
as far as I am to understand, crt's function differently than lcd (or other more modern display technology) in that they "draw" an image pixel by pixel moving left to right as signals are received through the inputs.
so the signals we are looking for are those currents directing the flow of electrons from the electron beam to the screen in order to illuminate each pixel correct?
what should this signal look like?
how does this work for pixels that are not lit?
this setup makes enough sense for a monochrome crt, but how do multicolor crt's work?
how does one rca cable carry video despite only having a voltage (analog to my understanding) and gnd pin, this makes enough sense to me for monochrome displays, but how does this work for multicolor video?
my home cooked guess is that the crt would be shifting between pixels at a constant rate, and the rca cable would merely dictate if the electron beam should be fired or not,
if this is the case, for color crts is there multiple tubes? and is each one awaiting a specific voltage through the rca?
and, continuing to assume this theory is correct, do all rca devices need to be outputting within what I would imagine to be is a very small tolerance for speed?
last question (apologies) is there any delay issues that could theoretically arise due to the distance necessary for the electron beam to travel to the screen?
apologies for all the questions,
but I believe its better to know how a solution works fully than to just fix it (if that makes sense)
hoping to go into either computer engineering or embedded circuitry design after highschool,
sadly I will not be able to work on ozzy until Monday, but will try to check a local market on Saturday for an osciloscope, there are often stalls selling misc old electronics with vendors who have no idea what they are selling
Thank you,
