[QUOTE="Switt23, post: 7529852, member: 559024"] Recently installed a Pioneer AVH-P4200DVD and when the unit powers on the screen is rather fuzzy for lack of better terms. It has vertical lines running top to bottom that do not move at all. They tend to get brighter and dimmer but i can't find a correlation to when it's brighter or not. I've double checked all the wiring and it's correct. Removed the ByPass module thinking I was getting some feedback off of it, but the screen remains the same. Originally I believed that the headunit was receiving too much power causing interference, but I have never seen interference this bad on a monitor. Can anyone shine some light on what they think this might be caused by?
