Moniter Colour fault

I HAD a MAG DX15F and lost the whites and had a yellow screen. located a dry joint in the circuit board on the base of the tube and could with pressure get pic okay, finally got up courage to dissasemble screening etc. and resoldered but now the picstays yellow??. had a friend look at it with a scope and hey presto the big burn up he is as doddery as me!!. the outcome two cooked transistors .. the problem is we cannot get any info on these they do not cross match with anything we have down here.. located maginnovisions web site and thought hey no problems !! you guessed it been 2 weeks sent emails to all addresses in their contact section and no replies got one from the sales department and said do not sell out side USA????!!! great eh. and all i wanted was info and possibly a copy of the circuit diagram.

can any one help with some cross reference to these.

1.. C2910 T4H

2.. A1208 T4M

they are transistors Q414 & Q413 on circuit board DX15N-HC-SD-E1

The out come had to buy a new monitor you can bet it was not another MAG

thanks in advance
