I'm still fairly novice - I can design basic electronics but not really a repair person yet. I want help fixing my TV, just as in references, guides and maybe interaction.
So far I changed some caps ... that were bad. First one, got 20 seconds of run time - the standby light was back. Turned TV on, after a while scrolling digital garbage. Then I changed the main high voltage smoothing cap in PSU 400v 120uF - and it ran for 3-4 hrs. Then same and now I'm back online looking for guides what to do next.

Process of elimination - possibly some more caps to change that seemed ok....
