Hey all,
Well I knew it was too good to be true. My Star Wars Trilogy projection tv/monitor developed the same problem it was said to have when I acquired it. Basically I get only a blue and green line horizontal lines across the screen. When I first got the chassis I touched up solder, specifically on the vertical deflection card and was able to get the monitor to work. My first thought is a vertical deflection failure, but being this is a different beast than what most of us work with, I may be wrong. I took a look at the 3 individual color tubes to see what was going on and noticed the green and blue were on, but not nearly as intense as you would normally see. The red tube didn't appear to be on at all. Seeing that made me wonder if it's really vertical deflection or something else. I think my blue and green might be a bit high still in terms of brightness because I had adjusted the brightness controls earlier in the week. The blue and green showed light retrace lines in test mode, but since I had already put the thing back together and accomplished the goal of getting the red turned down (it was definitely up too high) I didn't mess with it. I'm betting that's why I'm not seeing a red horizontal line. Anyway, I know these things are beasts and it may have been Cadillacman who was the only one to brave messing with these monitors because there is little to no info on them, but if anyone has any thoughts on this one I'd appreciate it. My first thought is that if it is a vertical deflection failure, I may shotgun replace that large STK chip that kinda clips onto the heat sink of the main chassis. I could also replace caps and triple check solder joints again. The only other question is what else, if anything on the chassis, controls vertical deflection? It would be really nice if it's all related to that vertical deflection card. Thanks all.
