sd p5075 k convergence issue

[aarrgg!!!]

I recieved a free tv from a friend. One day after I recived it , I noticed that the convergence on the blue is off. How do I access the service menu to try and fix it if possible ?

if you cant align it with customer menu,i believe this one might use one ic located behind the front speaker grill,behind removeable panel.stk 4277,upgrades to 4279.if so change it WITH original pioneer part.
