CNYMark;.... IF the convergence ICs are found to be bad , you NEVER change JUST ONE....(& they are bad).... IF you put 2 new tires on the front of the car & you drive on them for 1,000s of miles , they eventually will wear down , & will , with some people , go bald... You don't change just one tire , you change BOTH !!!! The same rule applies to convergence ICs... They BOTH wear out the same... Do you REALLY want to do this TWICE ????....SOON ??? The ICs are not that expensive..... Usually about $24 USD for BOTH... Post the "STK" numbers (I suspect STK392-110) & I'll find you GOOD replacements... OR you can use your own resources... I'm usually of the mind that the least amount of board soldering /mussing with, that fixes the problem is better than mucking up some ic pads on one that was working. IF you are that bad at soldering that you are worried about "mucking up some ic pads" , you best call a professional TV tech & let him "muck up some ic pads" & get paid for it....... But , on the other hand , IF you have some decent soldering experience (& it sounds like you do) , I'd give it a go.... IF you use a good desoldering braid with resin , desoldering should be relatively easy.... the red is now registered with the green, and the blue remains off. & Also the blue horizontal line , top and bottom are curved, rather than straight with the worst to the screen right and almost on, screen left. Confirmed , convergence ICs bad !!!!! Have fun......... Later...Ron.M........ Veteran & Retired TV technician
