SOURCE: T.V. Convergence
John, im sorry to have to tell you, you have the normal convergence break down, and any adjustment is not going to fix the problem. The Convergence ICs are bad in this set, and both should be replaced at once, as you do not want to pay another repair price 6 months down the road. In these sets there are no user replaceable parts, unless you know how to work on solid state printed circuit boards and understand about the TV safety factors involved. Good Luck Please do not forget to rate this thread.

It sounds like the convergence IC's are bad unless someone has got inside the set and tampered with some adjustments or the set has had a recent rough move. Other possibilities would include defective capacitors/resistors or connections in the convergence circuits or power supply area.

SOURCE: color convergence?
Can anyone give me the resistor values for location RK 42, RK 46 and RK 62? Hitachi 46F500 TV. Or can I be pointed to the location of a service manual?

hi..first check it out the brightness.It is available in the
menu button,available on the top of the tv.If it still doesnt
work Projection TVs have a high intensity lamp as the light
source. They wear out and gradually get dim.You probably
need to replace it.
check it out..
rate my response..

Would need model number to search properly. On some sets a capacitor "C2601" of Y-Drive assembly contacts the audio bracket and it is damaged, can cause a abnormal picture.
