1 Answer

Blue and Green line thru center red shadow on both sides

most likely if the line is top to bottom you have no horizontal deflection
this could be caused by a number of things
but if you continue to turn it on it will score a burn mark on the face of the three crts
id call a service ctr in your area or you might try replaceing the deflection bd and see if this will resolve the problem

the problem could be a open yoke return cap but if you dont have the tools or knowledge this woulld be one better left to sme one more experianced with this

please let me know il be happy to try and assist you further
