Ticking smps , caused by failing hot side electro on the supply V for the
switching ic driver. Uprated and smps is stable putting out right sorts of
higher DC , according to the schematics.
But the LV 3.3V etc regulators seem to be waiting for a control signal.
No display, no fan , no button function and flow chart on e-service is in
Russian but I suspect like the error code page needs the display up and
running . Is there something very basic to do or mantra to say?

Broken land number 23 on the main ribbon meant 17V supply was going nowhere,
not me honest, I always wrap proper cloth tape around these ribbon ends , to
beef them up, before inserting them. Someone else had tried repairing this
one. All functions seem to be returned as far as not connected up to a
screen is concerned so far.
