turns on for a second and does not display any images.I've checked the main voltages, they are in place, the processor is heating up, what should I check next?

Very likely you have short in one of switched rails olike 3.3VS/5VS/1.8VS etc.
Just locate the dc-dc converter and measure resistance to gnd on 3VS/5VS side.
