Very common problems for DLP tvs,will get worst as times go by.Tv probally have a problems known as a convergence problems,it is dead.Tv have colors lines R,G,B unlevel on the pictures?Crooked pictures have mis colors alignments?Yes.There is no way manually to do an adjustment to fixed for this.Try push the tv remote button that said Magic Focus button.If the tv have data processing never completely done and have a error message and stop.Ur tv 100% have a dead tv convergence board,the tv convergence board must have it parts to be replaced like 2 STK convergence ICS and some or all of it resistors too.Than tv will be able to run the tv remote Magic Focus again to have a 100% data processing with no error message,tv to fixed this problems.The shop will cost u like $300-350 for parts and labors.
