i have recently acquired a 61' samsung dlp. when i got it i was told it needed a new lamp. after replacing the lamp i determined the color wheel also needed to be replaced. so now with the new color wheel in my tv still dont work. when it has cable the screen has these gray lines going from top to bottom across the entire screen. the pip works . when my xbox is on the screen looks like its spinning but the color looks good. can anyone help ? or can anyone tell me what setting i need to change in the service menu to calibrate to the new wheel ?
