How can i fix a screen problem (pictures hickup) on my television?

hi,chances are your set is suffering from dry joints somewhere on the main printed circuit board,this is best dealt with by a qualified tv engineer,or someone with a sound electronics background as there will be some high voltages stored within some of the components.Dry joints occur when the original coating of solder cracks around the leg/pins of the component/s to the circuit board causing all sorts of intermittant symptoms as you describe.once resoldered,normal service is resumed,good luck.
