You put in the post in the wrong field, the title has a character limit. Does an external monitor work? You will not find any circuit diagrams outside of HP engineering department. Is there any display at all even very dim? Can you see if you shine a light on the screen.

an external monitor is not working,it showing no signal...it has no display at all but comes with blue screen at times.. but the temperature of the mother board heats up very fast and there is a particular i.c that is very hot even if it starts for just 2 minutes.
