Question about Mitsubishi WS48511 48" Rear Projection Television
Screen at the bottom is fine but the more you move up the TV the tv shows alot of lines and strong green color in lines you can visibly see. Can see strong red color in say words that might be on screen say on sports ticker or something, the letters are all there but A definite strong red letter of each first word is shown like the word done, there would be a red d the done is spelled out in normal white letters. anyone estimate cost or problem this might be!! TV is about 4 years old.

There is a screen the light shows through to project to the screen when this starts to fail the screen will have lines. it sits at the end of the light chamber. these are expensive to replace on some models.

Go into your service menu and try to adjust the convergence, if it does not adjust, the IC's ( chips) are bad in that circuit. Call a local factory authorized dealer to service your tv. The cost should run around $450.00. Good luck.

any repair shop can re converge the tv for you.id do some calling arond and get a few quotes to see what it would cost to have them come to you

Your symptom sounds like a damaged convergence IC.
While it is not a very hard repair, this repair can be a bit tricky. If you have a 45W soldering iron, solder, solder wick, and heat sink compound you can repair it yourself.
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.
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, 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.
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.

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.

What you might be experiencing based on your symptom sounds like a damaged convergence IC.
With any Projection Television that has a damaged convergence IC, 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.

I have attached some photos of really bad convergence problems; your picture may not be exactly as bad as these.

The conversion ics are probably going bad another common problem with this unit is fluid leakage on the convergence module this might be the problem also you must start out by seeing if that is the case both problems are repairable
