    Rear projection has no factory settings to correct convergence. there would be few parts damaged in convergence section in tv and causing color line-up.

How do I fix the color on the tv?


If the model number is correct here look on the back of the set not for model number but chassis number---suspect that is PTK195.

If that one and convergence is skewed fairly bad--easy repairs--just need a meter to check a few parts to know. Set has a common problem where one of two diodes shorts and convergence only partly works.

Red distorted color near top of screen not having much luck with trying to converge the lines on the tv set form. already tried factory reset


Reset will not cure a convergence problem.

this model (ws-65711) uses a single convergence chip located on the middle circuit board (see photo).

If convergence is skewed and will not adjust in customer menu the chip needs to be replaced.

Good news: I have start to finish, step by step instructions for this repair in this set. They tell you everything you will need and exactly how to do the repair.

No two sets with convergence problems will look exactly the same but I will also attach a few photos of this kind of trouble.

If the photos or what I have told you told you something you did not know and you want the instructions (free) rate this solution as very helpful as I do this here for free.

It looks a great deal like watching a 3d movie without 3d glases. The convergence is not correct. I tried to correct with a convergence back to factory settings and a manual correction from the remote. Not...


Common convergence problems like this require the set to be repaired. Transistors are used to control convergence and they will go bad eventually and require replacement. Expect a repair cost in the 100 to 175 dollar range depending on who you can find to complete the repair.

Your convergence is bad. If after trying the Auto Convergence option on the TV it doesn't correct itself, you can try manually adjusting the convergence Here is a link to perform a manual convergence on your set. Good luck!

Auto Convergence not working


I'm assuming you were having picture quality problems prior to pressing the auto convergence button. If not then there could be a problem in that circuit. More likely I believe is a problem on the convergence board assembly or in the pincushion circuits. Also, check your owners manual to see if there is a manual convergence adjustment you can do.
