Screen is bowed (top and bottom) Color has a green and purple tint?

My JVC AV-56WP74 has the screen bowed on the top and bottom. The color has a green and purple tint. The picture on the top and bottom is doubled with green and purple, i can see the picture in the middle of the screen (not clear). Someone said that i have a convergence problem. I will have to replace or repair the ic to solve it. What is ic? Where do i get this part? Should i just have a repair store fix this problem or just buy a new tv?

    I also tried to adjust the color convergence (Auto and Manual) with no success. Adjusting manual will only allow me to change the red ( no other color).

Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from www.TvRepairKits.com and do the repair yourself. Its a fairly easy DIY fix.
Here is an example video

You need to replace both convergence ICs they are STK392-110 you may want to get the resistor kit as your model will usually have a couple open resistors. You can get replacement ICs and resistors at the following link and they provide free instructions with pictures so you can easially do the repair your self.
Heres the link.

Double vision on tv with purple and green colors


Hello,

This television set, as well as most rear-projections, is prone to convergence driver problems. There are two large chips (STK392-110's) in the TV that need to be replaced, as well as some resistors that are likely damaged as well. Any competent TV repair shops should be able to repair this TV for 200-300 dollars. It is important to note that if the back of the TV is taken off without the proper prep., the Digital input (DVI) will be disabled permanently.

Hope this helps you...

Now I have the red out of alignment ad even after I did a reset and multiple manual adjustmets it is still off at the top and bottom af my screen.

You may have a convergence problem that means, there may be convergence ic's bad or related components.
If you know something about tv's, try checking things out.
You can get a repair manual from websites to download.
If you do not normally fix tv's the best thing is to call a tv repair technician.

You have a convergence problem. Components are shorted out and must be replaced. Unless you're a technician, there's really nothing you can do at this point.
