The problem is the convergence IC's - the are located (from the back) on the left toward the front of the set - i always change bolth at the same time - there might also be an open resistor in front the the ic that fas gone (2.2ohm i think) it should look burnt - on another note do not adj any thing in side the set!!!! the controles silly girl is talking about are not in your set - if you can not solder please do not attempt - if there is any thing i can help you with let me know
thanks

Technically speaking, there is no such thing as "ghosting" on digital TV. Ghosting might visualy describe it, but if you're not watching analog then that's not the problem. The problem is most likely in the convergence. First thing first - If still under warranty or if you have no electronic repair experience you should take the set back to the shop or to a repair person. Some of the solutions described below can be dangerous, TV's are very hazardous to service. Even when plugged out, TV's can store very high voltages. If you don't have any repair experience my suggestions can only be usefull to get a repair estimate, or in order to get more familiar with these kind of problems, impress your local repair person etc... some common fixes: switch to test mode to check the red crosshair compared to the green or blue - if it seems out of focus, open the set and mark the position of the lense. Then adjust it to tighten the line. Find out why the Red has shiffted(pin trouble). look for bad solder joints on that board. Its also Possible that you have a failed component. Try resoldering the STK Output IC's very carefully. In a worst case scenario , you may need to change the STK that controls the Red Convergence . Yank out the convergence board(the one that has several controls) on it, then you will find a few contols that have RED PIN (whatever). on them. Adjust them untill you get it right. Good luck

This is a convergence output IC problem. convergence board (main Board) would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually charge between $200-$300

We are getting ghost images and the color is not correct


I have red concave lines going across the screen, plus wording appears double like a ghosting effect, this is ongoing from the time the tv is turned on until it is turned off. This started 3 days ago. Is it time for a new tv, its 9 or 10 yrs old now.

Convergance issue on one AV input only


This is not a convergence problem in the traditional sense as it would effect all inputs not just one. I would be looking at the video switching IC as the defective part. I'll look up your model to try to get you more details. Are you going to attempt the repair yourself?

Thanks,
Dan
