Sync was stable enough that it would display on an LCD. Left it on a demo loop overnight and color has improved a little but now has jailbars. turned it off and it cooled down and now it's back to not syncing on an LCD and looking about the same as it did last night. Issue is presumably composite sync (unstable picture and lack of green), anyone think since warmth makes it clear up somewhat that cap replacement would fix this? or is it likely to be a connector issue and need a reflow?
