17 Blue convergence wont move not IC chip
OK, I got a good one for you techies...

so I replaced the ICconvergence chips and my 12 resistors, theapparently my 6.8 ohmresistors were not the right type "not metalfilm?" or my solder job wasnot up to par, either way 2 burned up. Ireplace then and the ICs withall new chip this time the quality ones.the TV run stable the redadjusts fine

HOWEVER,

1. The Blue convergence with notmove up and down just left right.I've tripled checke the sodder evenredone them and checked the ohmsthey are good...

What else controls the the "Blue convergence up and down?"
Iread the part manual from on line but cant decide if those 3 prongTransistors effect the convergence control and if so which one?

2.the Green "non movable fixed color" has a warp/bend top centerscreenthe top two center mulit point convergence points warp left. seebelowcrued sketch, also most of the center multi points red/blue areright onBUT the outer ring red/blue + are pulled in away from green
IGNORE THE DOTS, I needed them to hold the space to keep the lines from moving to the edg of screen in drawing
