When he did the '7 seconds off' test, the pic came in good at turn-on, stayed good briefly before the bars drifted back in.
Seems like if the fault were caused by a component other than a tube, the bars should be there instantly at turn-on.
Best WAG would be a gassy H out tube, 'specially since the width is affected also.
I honestly can't remember ever seeing a problem caused by a weak damper. All damper faults were either arcing or an open heater.
