Had the two convergence circuits repplaced a few months ago. now i noticed that the tv was showing 3 colors of the tv ratings when changing channels . i think they were red /grn /blue. I went in to the convergence setting on the tv, tried to manualy adjust them with the remote. and i even hit factory reset. this did nothing. the rest of thepicture on the screen looked pretty good. i turned the tv off and when i turned it back on , i get sound , and three vertical lines in the middle of the screen , all of them faint. i cannot get any picture on the screen , so i am unable to navigate the menus.. is there a way to reset the tv? or is the convergence gona again..

Very common problems,through out the DLP tv life cycles could happen again again until end of the tv life itself.The tv have a problems known as a convergence picture problems,it is dead.Tv have any colors lines like R,G,B mis alignments,have colors shadow pictures or 3D pictures look alike?Yes?Than the tv convergence board it is dead.The tv convergence board must have it components parts replaced like 2 STK convergence ICS and some or all of it resistors too.To fixed the tv convergence board to solved the tv convergence picture problems.The Shop will cost u like $300-350 for parts and labors.
Yes,the tv problems it is the same,it is the tv convergence problems again,now it just color it is shaded in shadows pictures,instead of wavies mis colors R,G,B mis alignments.Yes.The tv convergence board it is the problems,must be repair again.
THIS HAS NOTHING TO DO WITH CONVERGENCE or any of the stk integrated circuits.There are few capacitors close to the vertical output ic, they are usually blue or red (could be 1000uf 50volts for e.g.)That where the problem is
the tv color circuit is off frequency change the color ic take a look on the crystal that gives the 4.8.mhz burst could be that it needs to be replace dont rule out the video IF change the two ICs you mention.good luck.from the look of your tv screen that is my conclusion.good luck.email me at email@example.com
