Answers :

Common reason for this kind of trouble is a faulty circuit, where a defective component cause electrostatic charges accumulating on capacitors.\015\012
\015\012When you keep clicking the start, or leave the monitor resting overnight, you drain power, and unit restarts.\015\012
\015\012Try leaving the monitor unplugged from main overnight and see if this can help.\015\012
\015\012Also test the monitor on a different computer, as a shorted video cable can cause similar problems.\015\012
\015\012Parts that can commonly given this kind of problem are the Power supply board and the Inverter board.\015\012Sometimes a faulty digital controller board can cause the same problem.\015\012
\015\012If the power adapter is external , this is easy to test using a multimeter to read DC voltages. Volts must be within halv volt difference from value stated on power adapter label.\015\012
\015\012An internal PSU is more difficult to test, and for safety reasons the job should be done by a tech.
\015\012
\015\012Test starts with a visual inspection, looking for bulged or leaking capacitors.\015\012If there is nothing at a glance next step is testing voltages out and then testing components.\015\012
\015\012Same operations must be done on the inverter.\015\012
\015\012Inverter and PSU are high voltage boards.\015\012
\015\012Regards.
