i have the same problem but i'm just too lazy to fix it or replace it, from what i've researched it's usually because it's old the solder joints on the hud are weak, and you need to get them resolder'd or get the whole thing replaced, im not sure of the site but i remember like kaido sold a hud unit for 200 lol..expensive, i've found places that fix the hud online but they're all far away, i'm here in socal, kinda skeptical sending them my hud, dont' wanna drive the car around w/o a cluster
