Darrel,
We need more info to help you.. like voltages, did you check sweep
board for loose connections like at socket pins, regulators, current draw
running, leaky diodes...Most problems I have found on the 9-1074-01 sweep
board were leaky diodes {unsolder one end to test} and loose connections...
To Philips post, the bad picture tubes started on the SL and SM line.. 1
Year after the J line...In the J line when the tubes start going they get
very weak and don't {normally} short...
