Television and Home Theater

My IC chips went bad recently and i replaced them but before i did that i tried to adjust the tv with the magnet adjustment knobs and all that...which i know i was wrong to do :).  How do i reset the original position of the CRTs.  The tv is watchable but i definatly cant play xbox on it because the top of the screen is blurry.  It is not too noticable but to me it is and it is killing me.

I live west of Atlanta, GA and am looking for someone who repairs tv's in house. My mothers tv picture is shaky and was wondering if anyone in the area does in home repairs on a RCA 52" P56720LV. Please email me if anyone could help me find a repair person West of Atlanta, most repair shops in this town want you to come in.

I own a mitsubishi VS-50605 and just recently my big screen went out on the blink. A few seconds after turning on the set it turns off. however if i repeatedly keep turning on the set I get a snowy yellow screen. no blue. My tech tested all voltage and it was good. Checked all the CRT boards and their values were all in tolerance. Any suggestion of what this problem my be.
