What was "original" problem?

Model / Chassis Number could help.

Check electrolytic capacitors in same general area as IC (usually 100 to 220ufd).

finally got a chance to get back to the tv . i was checking around the caps close to the vertical ic and the largest one behind it i chose to try to resolder again as the more closely i looked , the solder joint looked suspect. even tho i had resoldered several joints in that area i may have overlooked this one. i took it out and put it back in . i did not check it first ,but after resoldering it i have no more lines on my screen . thanks for your patience . without your help i would just have a bunch of extra parts in a big black box. my grandaughter is going on 6 and she loves to watch clifford the big red dog on that set .thanks again for your help.
