I have a Toshiba model 19AV500U...recently it has decided to turn itself on and off..at various times day or night. Do I need an excorist or could it be the cable box or some other problem? ..
err i would recommend a exorcist o.o
but i think its what midi-magic suggested
edit: randomly at night? do you have any smart devices that run off schedules?
hmm your motherboard might be damaged
make sure your remote battery's are fully charged and check that theirs no schedule settings that someone like a friend or family might have set up as a joke might have set up
