Getting some little dots like the matrix coming from the top of the screen the dots are blue
The set will need some screen voltages adjusted on the power supply board, the VS voltage is marked on the panel inside the set, find the VS test point and the VS adjustment potentiometer. adjust the voltage down at least 10 volts, if your not an experienced person in electronics, get a person that is, there is a high voltage on that board that is dangerous
