Sometimes caused by bad wires or cable shorting. Check that all cables and connections are good and retry. If it doesn't clear you might have blown / shorted an output device in the amp section.

Display panel says protect as soon as switched on and can get no responce from any command


The protect message is an indication that a problem was found at the final stage of the amplifier. Typically, this is caused by defective output transistors. A confirmation of this can be made by removing the speaker wires and turning on the unit. If the protect message still appears, the problem is internal to the unit and it will require repair. The DAV series of units are not the easiest to work on and replacement parts are limited. I would suggest that you get a detailed repair estimate from an authorized Sony service center. Post the results here and we should be able to walk you throught the actual repair.

This is a common problem with sony it means unplug me or i will explode, it is a protection of the heat sync and usually means that a cooling fan has shorted out. If under gurentee return to Sony for repair if not under guranebntee as is generally the case check on the net for a replacement fan motor - as far as i know sony were sourcing thier fanns from Sunon there is a German based headquarters - just google sunon europe
