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.
