Hi there,
Installed my first backlight yesterday, and was playing through Gargoyle's Quest (big game from my childhood!) when the DMG random crashed to a blank screen with a single horizontal pixel line.
Product I installed was from Deadpan Robot: http://www.deadpanrobot.co.uk/en-gb/col oy-mods-uk
Now I'm aware that some people in the past have had trouble with installing resistors (or not), but these have resistors built in.
Could it be another issue that's causing this? I also had a problem with Pokemon Cock version pre-backlight, but since that's a hack and a chinese knock-off I put it down to that.
Ideas?
