Most likely this set has bad convergence amp ic's and some open resistors. This can be a very tricky repair.
Check:
resistors RK42, RK46,
RK50, RK54, RK58, RK62
Output STKs IK04, IK05.
Hopefully this will help. Thanks for using fixya.

Resistors " RK42 3.3ohms
RK46 1.8ohms RK50 2.7ohms RK54 1.5ohms RK58 3.9ohms RK62 2.2ohms After you replace all of them then enter convergence by pulling OFF bottom front panel there on front of convergence board is a small blue button press it and a convergence pattern will come up now aline each color red then blue.
Double check the numbers on the STK chips as most of these sets use STK-392-110 OR 392-150 CHIPS-----ONLY A FEW OTHER MODELS(MOST 43 INCH USE THE 120 CHIP.)

check ik04,ik05(stk392-110,if bad,replaced with stk392-150).resistors:rk46,rk54-1,5ohm.,rk42,rk50-2,2ohm.,rk58-3,3ohm.,rk62-1,8ohm.also check line fuses..
ok
upgard the stk392-110 to a stk392-150
note use flame proof resistors 1W
rk42=3.3ohm/rk46=1.8ohm/rk50=2.7ohm/rk54=1.5ohm/rk58=3.9ohm/rk62=2.2ohm

checked model it is correct 65xwx20b checked board looks like dp2x
