SnakeGrunger Posted September 14, 2018 Share Posted September 14, 2018 (edited) Hi everyone, I have a Vectrex of a friend of mine and asked me to do change all its capacitors, which I did, but one problem remained : uneven scanline distribution. Here's a video of the problem : As you can see, most lines (in text) and not evenly distributed, the corners on the startup screen logo don't touch either. Here's what I did : - Replace absolutely all the electrolytic capacitors on both the mainboard and power/video board. (and taking care of soldering on the top and bottom exposed holes that don't have copper going down the via) - Replace the 5 small styrene caps near the op-amp on the cpu board with film caps of equal capacity. - Replace all the single-wipe sockets with double-wipe. - Did the de-buzz audio mod which works very well. Does anyone have an idea of what may be wrong or which IC I should check more closely ? Thanks!
