point A on messiah 2 mod fit

[steve p]

thanks for your reply

i seem to think the ressistor that you solder onto (point A) sends some sort of signal to the cd/dvd controler
as i said earlyer this is the only mistake he made in chipping his station
i have had a realy good look around the board there are no bridges what so ever every thing is nice and neat what i would like to know are the possible components he may have damaged soldering the wire to the wrong side of the ressistor
i would be very thankfull for any info anybody can give to help retify his problem
thanks
