no problem. I've replaced quite a few that have done this... so much so, that i keep tubes of them handy and buy them in 5 and 10 packs...
the LM1269's and the LM1203's are bad for this...sometimes LM2421's
the LM1203's mainly cause the output transistors short and feed high voltage back into the chip and kill the output so if i'm replacing a shorted color drive transistor i don't even bother testing if it's just that, i do the chip too.
the 1269 used in the WG monitors is kinda a bad design i think having a user manipulated device go straight into an input without any kind of protection is asking for trouble. pull the plug and short the pins on the shield ground on the way out (or on the way in), and who knows.
in any case, I think that is going to be your most likely avenue of issue.
