Well there is no yellow, there is only red, blue and green, Blue is the set line the other 2 need to be aligned to. If blue is bent or out of alignment then there is a problem with some internal chips that would require a good deal of soldering skill
Problem is going to be in the Green and Blue Tube ,you need to change the Coolant Fuild out and out in New,Philips is well known for having Bad Coolant fuild in the G/B Tubes.
With Back Off and TV on Look down inside of each Tube you should be able to see a Clear picture, in each Tube, If you do Not then you need to change out the coolant fuild.
You also have a Screen/Focus Control Block, it controls the Screen Drive and Focus to Each Tube R/G/B 3 controls on top and 3 below them. Top 3 should be for Focuse and Bottom 3 Screen Drive /Brightness to each Tube.
Now in order to aline for Correct Color you will need to adjust all 3 Tubes , Turn Color OFF in Menu then aline the Tubes untill you have a Black and white Picture ,Then go back to menu and turn Color on.
I'm not sure what you mean by: "out of the 6 x 5 are out of line" If you are referring to aligning the colors on the screen, the settings you are looking for are called "Convergence". There will usually be a red, blue, and green cross you will have to line up perfectly. the green is usually not moveable.
youre convergence ICs need to be replaced. You will need two STK392-120 ICs . You can get new ones here with online free support to help you do the repair, plus they send step by step instructions with pics on how to do the repair. Here is the link. http://servicemanuals.vstore.ca/

Did you try alignment of color convergence in setting up. Try this
1 Press MENU
2 Select SET UP
3 Select CONVERGENCE
4 Select screen mode ZOOM this accesses the center convergence adjustment.Press set/enter
5 Use arrow keys to aline the red cross to the white cross.Press set/enter
6 Use arrow keys to alingn the blue line in the same manner. Once adjustment is complete press MENU to turn the menu off.
I hope this helps if you cant move the red or blue lines you face the same problem I face. I still havent gotton any solutions to my post about being unable to adjust the red line.You could also call Pioneer's help line 800-421-1404.
