Question about Mitsubishi WS-65711 65" Rear Projection Television
This TV has been a gem! It has HD 1080i and was ahead of its time 5 years ago. The playoffs are around the bend and it just started to go into doubles on the left side of my screen in pink & yellow or green. Letters are in double and the outline of a figure on the left side of the screen has a wide yellow/ green/ pink line around the figure. On the right side of screen as you face it, the same lines are thinner. Tell me it is not over! Just please tell me it is doable in terms of a fix without another mortgage attached!
The convergence modules have gone bad Along with the new parts kit are fuses, diodes, and resistors that usually fry when these modules go bad. Depending on the model, there will be two and sometimes 3 of these modules that have to be replaced. Each module has 50 pins each that have to be soldered, so unless you have experience with complicated TV repairs, the cost to do that repair may be as much as a flat screen TV of the same screen size as yours.

What is happening is that your convergence amplifier modules are beginning to go bad. These amplifiers are what amplify the signals used for convergence (how the RGB lights line up on each other) when they go bad the RGB lights tend to bow towards the center of the TV and the colors begin to mis-align. There are many sites devoted to doing the changing of the amplifiers yourself,however although these sites are accurate in give the instructions on how to change the amplifiers they do very little for actual troubleshooting and finding the underlying cause of the problem. In most cases its just that the amp modules have gone bad, but sometimes there is an overheating problem that triggers the damage. I would suggest having a TV repair person come to your place to check the problem and to fix it. The repair should cost about $250.00

Your symptom sounds like a damaged convergence IC.
There are two and large IC’s that control the convergence in a big screen set. 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, and they are located on the signal board (on the left as you look into the back of the set).
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.
There are also two resistors on the front of the board located in the middle that are fusible link resistors, these should be checked for opens and replaced if they are found so.
I would suggest that you contact a service center in your area for a complete diagnosis and repair, as this type of repair can get a little tricky. But if you want to repair the set yourself, just remember to be careful. The capacitors and CRT’s can hold a charge and may shock you.
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.

No,need to diagnose.It a 100% convergence problems.Convergence problems very easy diagnose.The picture look like 3D,colors lines don't lines up.Fuzzy,out of focus.Convergence controls don't work to lines up any colors cross.The tech is cheating u if he said cost $125 to diagnose.If u know how to solders u could fix this convergence problems about $100.U can buy a convergence kit at Websites Tv repair World.com,Tvrepairkits.com.The shop everythings fix parts and labors only $300.
