[TechAssist] Re: Zenith Model SJ2735L keeps Blowing H.O.T

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...

Bob,
