Most projects in life are "easy",if you know how.Chassis will have to be pulled,convergence IC's replaced w/top quality parts to prevent recall.Some excellant soldering will be needed for prevent maintenance,for instance,the steel jumper wires feedig b+ to convergence IC's. RE-align in servicer mode==final step.
