ws 65869 error 23

hello to all, maybe some will be able/willing to help me out.have a mitsu ws65869 thats giving me an error code 23 loss of loss of horizontal deflection.i have done the dm cap repair to this set before it was mine. i also changed out pc9a51 photo-coupler with TLP421 and ic9a51 ic error amp with NTE7215.worked for a week or so than started back with error 23.any ideas would be greatly appreciated.

well i went ahead and replaced the ic error amp and photo-coupler again in hopes that i had gotten some bum parts . now comes on for a few seconds before it shut down. screen jumped a little  then horizontal lines  mostly in the middle of the screen bofore it shut off...any ideas?
