Hi all - trying to get this Tron working - yesterday got no picture (but neck glow). Pulled the chassis, resoldered a few suspect joints. Monitor now shows a nice blue line straight down the middle.
I looked up the problem here and Modestsitt / Dokert had similar issue in the past - it was suggested to reflow points around large white resistors and shielded transistors on the chassis - just did that (they looked ok to start, but did them over again) and still an issue - blue line straight down the middle (game does 'play' though).
By the way - while re soldering the boards, TWICE around C702 (a cap i just put in) i get "sparks" which is strange isn't it?
Could this be purity / convergence rings out of adjustment by any chance - they were moved (unknowingly) and expect they need adjusting anyway.
Any advice on what to check next? Any help is appreciated.
