HCM780M Complaints & Reviews

I am using a HCL Computer with monitor HCM 780M . It has a problem related with the monitor . While working the monitor switches off automatically . After 8 or 10 hours its switches on . Again it goes off when working 1 or 2 hours and switches on after 8 or 10 hrs. Please help to solve this problem. Is the circuit of the monitor available. Who was the publisher of the circuit diagram? How to solve this problem. I request from monitor technicians....
