    I have been pressing the Magic focus. Sometimes it will do the red, then blue, then green pause for about 10 seconds go to a black screen and it gives me a 3 or a 4? I read in my operators guide that I have automatic Magic focus not manual?



    Does that help?

Colored lines at top and bottom when tv comes on and seeing double vision in different colors at all times
If your tv is not a DLP the problem is in the convergence, try to adjust it using your original remote control go to the setting menu then to the convergence section. Adjust the red and blue convergence. you should move the red and the blue in up, down and left, right if this color does not move far enough your convergence IC is already defective. Replacing this convergence IC will solve the problem. In locating this convergence IC you should remove the back cover of your unit but be sure to unplug it before doing this. This convergence IC is attached to a large aluminum plate, it is the heat sink, and it has a marking of stk- ### followed by numbers. You can try to pull it out using a soldering iron and soldering pump but be careful you may damage the board and cause much problem to your unit. Or you can contact a technician to do it for you and save you from stress good day and best regards.

My screen to my RCA 56" HD TV is messed up. The picture seems to be bowed inward and the colors are all mixed up. I tried to do the convergence but it is not on the menu and I remember it being there...
t is the problem of convergence setting or convergence IC.

My Akai projection tv the color has bad color and double vision. Why?
If you have an older model projection set then the Convergence Ic's have gone bad. This type of repair usually cost around $250.00 to repair and can be done in the home by a technician.

My tv looks like it has double screen....for example a picture of a tree....right next to it would be another tree....double vision...
This is not a LCD tv,It a DLP tv.This tv have a problems known as Convergence problems.The tv convergence board the 2 STK convergence ICS and some or all it resistors are dead.These parts on the convergence board must be change to fixes 3D pictures,shadows colors pictures and Green,Blue,Red colors misaligns,don't matches up to form a good picture.The shop will u $300-350 for parts and labors.

57HX81 projection tv,color is mostly red and picture is double.
This is a convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually charge between $200-$300

Screen plays double
It is called convergence out IC failure and you need to replace 2, ICs in convergence section of TV.

If you are familiar with TV repair or can solder electronics parts in circuit board then let me know exact model number of Panasonic TV to guide you more with technical info or call local TV repair shop for repair.

You have a convergence problem.
Maybe need change the IC of convergence, or the power supply of these parts.

Not sure if you fixed your problem already. But the answer is a color convergence problem. You can try adjusting manually via the remote and if that doesn't work it is most likely the two main IC chips that control the color convergeance. It is also possible that not only the IC chips have gone bad but also there are a couple of resistors that usually burn out with the ICs as well. They will need to be replaced. This isn't something that I would attempt on your own. Typically a TV technician will charge between 300 and 400 to fix at your house.

Double vision with a lot of yellow color
This looks like bad convergance. If only one color is affected it may be one of the convergance IC's. It is best to replace both IC's though. If you change the IC's then check the resistors next to the IC's. Use the exact part numbers. STK392-110 IC's can be upgraded to a STK392-180 for better heat strength. (That is why they blow, too much heat generated. Use a liberal amount of Silicone Heat sink compound.) A shorted IC will usually blow a resistor. If a bad resistor that isn't changed it will look like the new chip is bad. Make sure that you use the same wattage and the exact value (Ohms). Your convergance will not be right with an off value resistor. This info works for about any other brand Projo TV. Cheers, Lee http://www.crazycomputers.com
