I have a Mitsubishi 55"

This set has a convergence problem. You should only need to replace the IC. Part is STK393-110. It sits on the middle board behind the large heatsink. Use a heat transfer compound to ensure repair lasts. If you have no experience soldering (or unsoldering) please use a professional for the work. The traces are fragile and I have fixed many mistakes local DIYers have committed. Goodluck.

Our tv is blury, double vision with whites going

There seems to be two problems with the unit. The first symptom indiates your convergence IC's needs to be replaced. The second symptom coud be a several things, 1. Bad connections on the Crt board of the green tube, 2. The 200v screen bias voltage supplied by the flyback could have bad connections on it. Seems you have intermittent cold solder joints. Check the D board around the Flyback area for bad connections, or old grey looking solder connections all should look shiny. 3. The Green Crt maybe going faulty, the lines going thru the picture are scan lines and indicates that the Screen controls are to high. But i know you have'nt adjusted these so i would suspect the Green Crt is Faulty. But check solutions 1&2 first, One way to find out if its bad is to unplug the green crt board from the tube and turn the set on if it stays on and does'nt shut down then it is faulty, also while turning on look at the crt's neck for sparks which indicates arching in the tupe and will need to be replaced. Replacing the Convergence IC's will solve the distorted pic issue.

Screen has too much green all of a sudden

Try balancing the tubes out, turn your color all the way down and the brightness in the middle, then find the focus block, it will be a block with 6 controls one row will say screen the other will say focus near the picture tubes, adjust the screen controls(one control for each color) until the picture has a good black and white look to it, then turn your color up and it should look fine. This is how i balance out the picture. But there is another method that allot of techs use, the other method is to adjust the brightness up until you see what is called retrace lines it is a jagged line going down the screen, once you see these lines back the adjustment down just until they disappear. Do this for all three colors. This method works but on an older set can throw the white balance off because of tube wear.

Sony 43 inch rear projection tv, I have lined up the convergence but still seeing red and green around edge of the tv on the images, seems fine in the middle of the screen though.

Always start at the vary center of the screen with Green. Position Red over Green, then Blue over what now will look yellow. If all is perfect except the outside, you will need to adjust "Mid-Size" until the middle is just as far off as the outside lines. Then adjust the main "Size" adustments to match. Go very slow or you can make a mess of it.

Problems with green arching lines

yes there is a small black box with 6 controls on it, take off the bottom front of the tv, behind that you should find a black piece of plastic you can remove by taking out 2 more screws. the black box should be in the upper i don't remember if the top 3 are the screen controls or the focus controls. the rows should be labled, you are looking for the screen control row. the green control is the middle one. you can try turning down the control till you no longer see the green lines. try adjusting in a dark room, it will be easier to see the lines & when they are gone. if you problem is not solved by trying this, then i agree with your tech & the green tube is bad. good luck.
