Turns out I put it too high (above the little solder point) so I had to bridge the connection and cut lower. Working great now! Pics just for fun.

]]> https://chipmusic.org/Category 2014-10-09T10:19:05Z https://chipmusic.org/forums/post/218733/#p218733 I'm doing a backlight/bivert mod and I've run into some trouble. I've lost all shades of grey. Light grey is appearing as white, and dark grey is appearing as black. Other than that, the bivert seems to be working ok. I've checked for crossed wires and continuity with a multimeter and everything looks like it should be fine. However, it's just acting like the bit 0 wire isn't connected at all. In fact, the screen looks exactly the same whether I have that wire connected or not. I tried resoldering to rule out a bad connection but everything appears to be fine. Any tips on this?
