Just replace the color wheel

most likely the two convergence Ics need to be replaced. They are STK392-110 you can get replacements at the following link with free instalation instructions with pictures.

if it is hooked up with component cables, the red blue and green one could be loose or bad. ouble check that. also bypass the box completely and hook the cable straight into the tv and see what the picture looks like. If its good then something is either wrong with the component cables, cable box or TV itself. If you have multiple component inputs on the tv, try a different one and see if the problem still exists. it is possible that the board on the tv is shot as well. Call the cable company and have them take a closer look.

Try updating the software first :)

If you try to adjust convergence with the flash focus, perfect focus, (depending on the make of your set) or by manual convergence and the lines will not line up or even move. What you might be experiencing based on this symptom sounds like a convergence IC problem. But if the set fixes itself you will need to have it repaired as soon as possible if you wait too long there are several components that will fail in due time. If you want to repair it yourself or know someone that can solder components on the circuit board, you will need to re-solder the convergence IC’s. All you will need is some solder wick, a good 45W soldering iron, Acid free solder and some solder wick (this is for the clean-up of solder joints and cleaning up solder bridges.
I have repaired hundreds of these sets, so if you have any questions after reading the following, please reply to this post and I will help you in any way that I can.
With any Projection Television that has a damaged or interment convergence problem, you do not want to continue the use of the set. If the IC’s continue to fail they will cause a short in the power supply and cause your television to not power up, and possibly damage the CRT’s in the set.
With that aside I have some support suggestions that I have put together that may help you make an informed decision.
You should be able to get a local service center to repair this at your house for between $350.00 - $450.00, If you want to repair this set yourself, I have some instructions below that will be a help to you.
While it is not a very hard repair, this repair can be a bit tricky
How do I tell if the IC’s are damaged?
When looking at the area around the convergence IC’s you see some resistors that have changed colors, or you test a resistor and it no longer reads the marked value. You will have to replace the IC’s and the supporting components.
When you remove the old IC's, please be sure to remove all of the old heat sink compound, as it can act as an insulation for the new IC's and cause them to overheat. I usually clean the heat sinks with alcohol and a small rag.
Where are the IC’s located and how do I find them?
There are two and large IC’s that control the convergence in a big screen set. Some of the newer sets only have one. If you only have one, it is right in the middle of the set on the center circuit board. They are secured to a very large aluminum heat sink. They will have a part number stamped on them that will start with an STKXXX-XXX, like STK392-110.
Along with the convergence IC’s there will also be some associated components that will need to be replaced as well. There are some resistors that are part of the convergence circuit that will be open and need to be replaced. Most likely these will appear charred in the center. If you have an Ohm Meter or a DVM, check all the resistors that are close to the IC’s and you should be looking for either ones that have opened or have changed values.
If one of the convergence IC’s are found to be bad, I would replace them both, if one has gone bad the other may go soon. I usually order my parts from Andrews Electronics in California, they will have the OEM components that you will need.
Their site is http://www.andrewselectronics.com/welcome.aspx
And their phone number is a 24-Hour Order Desk: (800) 274-4666
I recommend the phone order so you can talk to the person about the different types of IC’s that are available.
I would also advise that the convergence IC’s be OEM or better, just because they are cheap does not mean that they are a good deal. I have seen the cheap IC’s fail after a short time, even though they look exactly like the OEM IC’s. I think that the bottom line is that you will get what you pay for when it comes to the parts.
You can also try http://www.tvrepairkits.com/ , I have not tried them yet, but they do carry OEM or better parts.
I hope this information allows you to resolve this issue.
If you need further assistance please comment to this post and I will try to help you further.

I have attached some photos of really bad convergence problems; your picture may not be exactly as bad as these.
SOURCE: panasonic pt43lc14 no red color. picture is good.
This TV actually has 3 LCDs as part of the projector assembly. One Green one red and one blue I would guess. either the red LCD is out or the control board is faulty.

Hello Kevin,Please tell us what your current input device is and how it connects. Please try another input device to see if its your TV or the device producing the video.
